Walrus Audio

Notes: Inspired by the vintage Bell and Howell 385 Filmosound projector that guitarists have modified and used as guitar amps, Walrus has created a dynamic and responsive overdrive modeled after the projector's tone.

The 385 was developed to have the same simple but effective tone control as it's older relative, but unlike the projector, the 385 breaks up the single tone control and integrates separate, boost and cut bass and treble, allowing the player to get more creative with mid-frequency scoops and bumps allowing for a much wider array of tones to be achieved.

The pedal is internally running at 18v, which helps us nail the same dynamic feel of the amp in a stomp box.

This means it is extremely sensitive to how hard you dig in - just like the amp.

Updated for 2023.

Controls:

Bypass: Soft touch, relay true-bypass. Press the switch to engage/disengage the pedal. LED indicates whether the circuit is engaged or not.

Notes: Sync all your time-based devices, seamlessly move through preset setlists, and simplify tempo matching with the Canvas Clock! Designed for any kind of rig you throw at it and deeply customizable, users can put their full trust in the Clock to be an all-in-one tempo solution for their board.

The Canvas Clock can interface to any device in your rig that accepts clock signal, whether MIDI, (via the 1/8 in or 5-pin MIDI ports) or analogue (via the 1/4 in jacks). Clock will send time signals for both MIDI and analogue devices, and will continue to do so as you move through your song list or manually adjust the tempo. As you edit, save, and recall songs in real-time or via the online editor at walrusaudio.io, Clock will send your specific settings for whichever song you are currently on out to all of the time-based devices you are connected to.

Customize your Clock

The four 1/4" in jacks aren't just for sending tempo. They can each be assigned one of four functions:

Tempo Out - Connect to any pedal or device that accepts external tap inputs or analogue time controls (ex: Walrus' Arp-87 Delay or Monument Tremolo). Canvas Clock can send analogue clock and MIDI clock at the same time. No more relying on your feet to keep perfect time.

CV (Control Voltage) Out - Control any device that accepts CV. Good for Analog Synths, Drum Machines, or similar devices.

Switch Input - Each jack can be configured to receive input from two external footswitch controls. The switches are connected to the Tip (left) and Ring (right) of the associated 1/4 in jack. These can be assigned to many functions available on the pedal with the ability to add more options via a software update.
Expression In - Connect an expression pedal, and use it to send a MIDI CC message out to a pedal connected to the Clock. The "Toe Down" and "Heel Down" values can be adjusted to fine-tune the controlled parameter range. Use this to adjust the mix of a reverb or the depth of a tremolo (via MIDI out).

Footswitches

Footswitches for the Clock are customizable. Eliminate the "bending over between songs to make adjustments portion of a set" by assigning one of the onboard functions to the A and/or B switches:

-Advance to the next song
-Go back to the previous song
-Advance to the next setlist
-Go back to the previous setlist
-Toggle the metronome start and stop
-Global tap tempo

Sync

The "Sync" jack found on top of the pedal can be set in two ways:
-Input - Great for accepting BPM from an external source.
-Output - Great for syncing external devices, such as a Eurorack device, a Roland Volca Synth, and many other devices.
Some external devices send/receive clock signals that are "double" the standard timing signals, so Walrus included the option to send/receive a 1x or 2x signal, depending on the specific device's needs. Users can also determine the subdivision of the BPM to send out.

Metronome


If active, the Clock metronome can be heard via the MET OUT port at the top of the pedal. This signal can be sent to a front of house console for live gigs or a monitor for practicing. Metronome type, volume, and accent note controls can all be edited in the Metronome Menu.

Songs

There are 128 "Song" slots available to users in the Canvas Clock. You can think of each song as an editable preset where you can adjust the song name, meter, BPM, MIDI Macros, and metronome start or stop. Once your song is edited to your liking, every time it is recalled it will operate just the way you set it!

Setlists

Keeping your songs organized is crucial for live sets, which is why with the Clock, songs can be grouped together and navigated through easily using the Setlist feature. Once you access setlist settings, you can select songs from your master song list to curate and reorder in the way you'd want them for a gig or practice. Once your setlist is saved and active, going through the setlist in real-time will recall these songs and all their settings in the order you curated them for that setlist.

MIDI Macros

For the MIDI-minded players who may want further control over their rig, there are standard MIDI commands that can be triggered when you recall songs with the Clock. MIDI Macros allow users to create one or a series of MIDI CC or PC messages that get sent out of the Canvas Clock when a specific song is recalled. Users have 128 adjustable Macros with 15 messages per MIDI Macro, which can be useful in further dictating how you want your MIDI devices to behave during certain songs, (ex: bypassing some pedals but engaging others).

Walrusaudio.io

While you can edit and customize your Canvas Clock settings using the menu on the pedal, users can also connect the pedal to a computer via the USB-C port and customize their Clock with the Canvas Clock Editor web-app. Quickly and easily set up songs, edit your Setlists, edit MIDI Macros, and more. Firmware updates will also be available via this site as well.

Notes: Canvas Power Supplies bring simplicity and modularity to powering your pedalboard. Delivering up to 500mA of silent, isolated, and clean 9V power to each output, these power supplies are perfect for the modern pedalboard. The Canvas Power series is built using modern switch mode supply architectures. This means each output is isolated, highly efficient, and heavily filtered ensuring they supply plenty of power with incredibly low noise.

Each model is available for purchase as a standalone power supply or as a linkable unit to another supply via 24v power link, allowing Canvas Power to grow with your power needs without adding another cable you need to plug into the wall.

Note: to purchase a Canvas Power 5 Link select the Link option AND 24v Link Cable option together before adding to your cart.

The super slim design allows Canvas Power Supplies to fit under nearly any pedalboard, and the included universal mounting brackets mean you don't have to worry about your power supply staying put when you're hustling to your next gig.

The onboard LED power meter lets you clearly see how much power consumption is remaining, and each output has its own LED indicator letting you know when it's sending power.

Walrus Audio have also developed custom 2.1mm barrel cables with a 90-degree plug on one end, and the all-new super short straight plug on the other, giving you the maximum flexibility for fitting these power supplies into tight spaces. Of course, they all accept standard 2.1mm barrel cables as well, but they won't be nearly as cool.

Canvas Power 5 Details

The Canvas Power 5 has 5 isolated power outputs delivering up to 500mA of clean power at 9v. One of the outlets is variable voltage, letting you switch between 9v, 12v, and 18v for powering high-voltage pedals.

Notes: Consider this your clean slate. The Canvas Stereo is a Direct Box/LIne Isolator designed to remove any resistance between you and your audience by giving a pristine, sonic foundation to build your stereo masterpiece upon. From houses of worship to the dive bar downtown, Canvas Stereo is built to be the performance tool that goes wherever you are making your music.

Canvas Stereo is a Passive Line Isolator (LI) and Direct Injection (DI) device that converts your unbalanced signals into balanced signals for interfacing properly with your recording interface or mixer at front-of-house. If you're using an amp-in-a-box (DSP Guitar Rig), like our ACS1, keyboards, or any other instrument utilizing both left and right outputs, then the Canvas Stereo is your new bridge to the front-of-house. The Canvas Series DIs pack everything you need from a DI/LI into a standard pedal-sized enclosure designed to look great right on top of your board.

Direct Injection:
Use DI mode when connecting an unbalanced, high impedance source (Electric Guitar, Bass Guitar, etc). The signal will be reduced by -20dB (-35dB with pad engaged) and converted to a balanced signal via the transformer connected to the XLR output. Use the gain on your mixer or preamp to bring up to line level.

Line Isolator:
Use the LI when needing to connect your unbalanced, low impedance source (Amp + Cab Sim like the ACS1, keys, etc.). The signals will remain full volume and be converted to balanced signals via the transformer connected to the XLR output. Less preamp gain will be required in LI.

DI or LI?
When deciding between DI or LI, check with the manufacturer of your gear to find the output impedance of the device you are wanting to interface. For a general guide:High Impedance = anything above 1k = Use DILow Impedance = less than 1k = Use LI .

Troubleshooting:
This is a passive device, so you will not damage anything if connected improperly, but it could affect the signal level and frequency response if not connected properly. This is an easy thing to test since the LI/DI switch is built into Canvas. If you lose high-frequency information when using LI mode, then you should probably be in DI mode.

Notes: Delay and granular sampling combine to create unique ambience effects, creative reverbs and glitchy chaos. Hugely versatile pedal with five contrasting programs.

Supplier's Notes:
In the high woodlands of the north, undiscovered by most inhabitants, there ruled a clan of old, mystic Treefolk. On the first new moon of spring, these Treefolk could be heard grafting limbs to grow their young - splicing bits of branches from each generation to produce the next line of Treefolk. These new beings keep the lifeblood of all who came before in their new skin. These sounds are in part very old, but in part very new. They are referred to as... Fable.

Let your storybook adventure grows with the Fable Granular Soundscape Generator. The Fable gives you five all-new programs centered around sample and chop delay algorithms to create bizarrely beautiful networks of sampled and resampled sounds. The Fable uses a powerful dual DSP architecture to combine delay programs in series with granular sampling algorithms, each with its own analogue feedback path. Find unique soundscapes ranging from smooth, flowing ambience; to bizarre, organic reverberance; to chaotic, glitchy swarms.

So, what exactly is this granular effect and why is it a magical experience when combined with delay? Granular is a digital processing technique of micro-sampling, wherein short samples called grains are read from a delay buffer. In the Fable, players can adjust these grains by manipulating their sampling length, position, and buffer size from which they're read. They can be played at double or half speed for pitch shift and time stretching effects, play them in reverse, read from multiple positions, and more, in order to achieve different effects.

It's a powerful but complex technique and Walrus Audio created five streamlined programs in the Fable that explore different aspects of its sonic range.

Programs

I. Reverse Delay into Reverse Granular

Program 1 runs a reverse delay into a reverse granular algorithm, in which sampled grains are played backwards. Reversal and re-reversal build up in the feedback paths, creating a complex and organically shifting soundscape. Turn grain size down for long, smooth reversed transients, and grain size up for stuttering reverse glitch madness.

II. Forward Delay into Octave Up Granular

Program 2 runs a forward delay into an octave-up granular program, in which sampled grains are played at double speed. Swarms of double-speed grains build up in the feedback path for bright and airy cascades of sound.

III. Analogue Delay into Octave Down Granular

Program 3 runs a warm, dark analogue-style delay into an octave-down granular program, in which sampled grains are played back at half speed. Slowed down repeats combine with analogue-style processing to create deep, thunderous footfalls and thick, murky ambience.

IV. Multi-Tap Granular into Multi-Tap Granular (Grain-Verb)

Program 4 runs two multi-tap granular algorithms in series, in which multiple samples are played back from each granular buffer simultaneously. Multiple points of sampled sound build upon each other in the feedback paths to create glitchy clouds and unique organic reverberance. Time in this program controls time-stretching of both granular algorithms, changing both the length and tonal character of the granular effect.

V. Forward Delay into Randomized Pitch Granular

Program 5 runs a forward delay into a randomized pitch granular program, in which each grain is played back at a randomly selected speed and direction, varying between pitched up double speed, pitched down half speed, normal speed, plus forward and reversed playback from grain to grain. Pitch changes with each new grain, so play with the X knob in this program to control the rate of randomized pitch modulation.

Notes: For the Fundamental Series, Walrus Audio challenged themselves to design a set of pedals with the tonal integrity that's required to live on a professional's pedalboard, but with simplified controls friendly enough for even the newest effect pedal users. Each Fundamental pedal has three faders for tweaking the sound and a three-way switch for changing pedal modes. The result is a line of pedals that will keep you covered from your first band practice all the way to a sold-out arena. Designed and assembled at Walrus Audio headquarters in OKC, OK.

Because vast ambient sounds shouldn't just be for larger pedals with vast price points, the Fundamental Ambient brings expansive pillowy reverb to the Fundamental Series with three atmospheric modes in a compact size. The Fundamental Ambient offers a great entry point into ambient exploration with the tonal integrity to live on a professional's pedalboard but with simplified controls friendly enough for even the newest effect pedal users. With Ambient's three reverb algorithms, you can experiment with deep, dark pad-like sounds to AM Radio-like lo-fi sounds with the flip of a switch.

The Fundamental Ambient provides three different atmospheric reverb algorithms to explore beautifully vast and lush soundscapes with plenty of decay time for pillowy soft pad-like decay.

Modes:

Deep - A dark ambient reverb with an added low octave, perfect for creating murky, cavernous sustain or adding a touch of moody atmosphere.
Lush - A breathy, expansive reverb featuring ultra-long sustain. Perfect for generating silky pads and immersive soundscapes with every note.
Haze - A textured, lo-fi reverb featuring distortion, sample rate reduction, and a resonant bandpass tone control, great for vintage or experimental tones.
Decay: Control the amount of reverb decay time. Left is the minimum and right is the maximum amount of time.
Tone: Shapes the overall tonality of the reverb. On Deep and Lush this controls the cutoff of a synth-style lowpass filter. On Haze this controls the width of a resonant bandpass filter, filtering both high and low end at the right, and allowing more high and low to pass through at the left.
Mix: Control the mix of the effect and the original clean signal. All the way to the left outputs only the fully clean signal, and all the way to the right outputs only the affected Reverb signal.
Slide Switch - The slide switch allows you to change between three distinct Reverb algorithms.

Trails Mode - The Fundamental Ambient Reverb comes with trails mode active by default, to disengage trails mode hold down the bypass stomp switch when applying power to the pedal. Once the LED flashes it indicates that trails mode is turned off. To re-engage trails mode, repeat the process, and wait for the LED to turn dark, indicating that trails mode is back on. With trails mode active, your reverb decay will fade off naturally after turning the pedal off. With trails mode inactive, the decay abruptly cuts off when you turn off the pedal.

Notes: The Fundamental Delay provides you with the core sounds of repeated effects. With three delay algorithms, you can go from clean digital feedback to an analogue delay emulation, as well as reversing your trails.

Time slider controls the rate of the delayed repeats.

Feedback slider sets the number of repeats.

Mix controls the mix of the effect and the original clean signal. All the way to the left outputs a fully clean signal, and all the way to the right outputs only the delay repeats.

The slide switch allows you to change between three distinct delay algorithms:

Digital: add a clean rhythmic delay back into your signal, with transparent repeats.
Analogue: add a filtered and slightly distorted delay back into your signal, designed to replicate the characteristics of bucket brigade delay chips.
Reverse: add reversed trails back into your signal, create gentle melodies, or push into reverse feedback overload.
Tap Mode: To enter tap mode, hold down the bypass stompswitch until you see the LED flashing. Once it is flashing, tap mode is engaged and the stomp switch will only work as a tap tempo until tap mode is disengaged. While tap mode is engaged, adjusting the program Slide Switch will only change the division of the tap control, and not the delay program. To disengage tap mode, hold down bypass again until you see the LED turn back to solid white. The pedal will remember the tempo you have tapped in until adjusted again by either the time control or another tempo is tapped in.

Trails Modes: The Delay comes with trails mode active by default, to disengage trails mode hold down the bypass stomp switch when applying power to the pedal. Once the LED flashes it indicates that trails mode is turned off. To re-engage trails mode, repeat the process, and wait for the LED to turn dark, indicating that trails mode is back on. With trails mode active, your delay repeats will fade off naturally after turning the pedal off. With trails mode inactive, the decay abruptly cuts off when you turn off the pedal.

The result is a line of pedals that will keep you covered from your first band practice all the way to a sold-out arena. Designed and assembled at Walrus Audio headquarters in Oklahoma City, USA.

Notes: Reverb and reverse delay go to the next level with this "ambient creation machine". Two DSP circuits with analogue feedback allow you to create epic soundscapes, time-stretching effects and more.

Supplier's Notes:
Once upon a time, in a fairy tale world, there stood a hidden forest. On the eve of every full moon, magical and delicate sounds of light were heard bouncing and reverberating through the trees. These sounds carry artifacts of notes moving backward and stretching through time. They are referred to as... Lore.

Create the soundtrack to your storybook adventure with the Lore Reverse Soundscape Generator. Made up of five different programs, each utilizes different combinations of delay and reverb that feed into each other for time-warping ambient creations. Featuring two DSP chips running in series, each with their own analogue feedback path, the Lore takes you on an adventurous journey rich with themes of reversing, time-stretching, pitch-shifting, and vast ambiance.

Having two analogue feedback paths allows each program to incorporate a unique mix of affected and unaffected feedback. The two feedback paths interact and build off of each other organically, offering the user a wide array of sounds and behaviours to experiment with.

Programs:

I. Reverse Delay into Reverse Reverb: Program 1 combines reverse delay with reverse reverb with a focus on organically interacting feedback paths. Space and ambiance build as the signal is reversed, re-reversed, reverberated, and reversed again within the feedback network. Experiment with the X knob to control how reversed your delay trails are with left being least reversed and right being fully reversed. Lots of fun with big, eerie minor chords!

II. Reverse Delay into Octave Up Reverb: Program 2 is a "light reverb" that combines octave-up harmonic feedback with an expansive, airy, reverb tank to create a breathy, spacious ambiance. Use the Regen knob to introduce a playful shimmer into the reverb decay. Increase the X knob to control the decay of the reverb. It sounds especially great with delicate fingerpicking parts.

III. Reverse Delay into Octave Down Reverb. Program 3 is a "dark reverb" that combines octave down harmonic feedback with heavy filtering and harmonic distortion, to create a sound that is thick, rich, and murky. Use the Regen knob to bring a lower octave into the reverb decay. Increase the X knob to control the decay of the reverb. Add in some high gain or fuzz to alter the time-space continuum.

IV. Reverse Reverb into Forward Reverb. Program 4 is a dual reverb program, featuring reverse reverb into forward reverb, Dual harmonic feedback paths allow the user to dial in octave up and octave down, and time stretching allows for control of the size and character of the space. Perfect for instantly transforming guitar into rich ambient pads. Use the Feedback knob to add a lower octave to the reverse reverb. Conversely, use the Regen knob to add an octave up to the reverse reverb decay. Control the decay of the forward reverb with the X knob. To channel all things ambient, experiment with dynamic picking and strumming techniques with the mix fully wet for ethereal drones and pads.

V. Pitch Delay into Pitch Delay. Program 5 features two "duelling" pitch delays, which shift the input signal up and down in complementary or opposing directions, allowing the user to create intricate harmonic patterns in the feedback network. Behaves like a sequencer at higher delay times and like a harmonizer at lower delay times. Use Feedback and Regen knobs to control various amounts of pitched delay repeats. Use the X knob to change the order of the 4th, 5th, and octave intervals that the pitch delay steps through. Experiment with short staccato notes to create some very interesting rhythmic parts!

Dive / Rise - Holding down the tap tempo switch will momentarily shift the clock rate of the pedal down or up and will hold it at that rate for as long as the switch is pressed. The direction of the dive can be changed by simply pressing bypass and tap simultaneously. A green LED over tap will indicate rise is set and a blue LED will indicate that dive is set.

The Mod knob will control the amount of modulation applied to the wet signal. Holding down bypass and adjusting the Mod knob will adjust the modulation rate. The bypass LED will blink to show your set mod rate.

Notes: The [ACS1] is an amplifier and speaker cab simulator delivering the sound and feel of world-class amplifiers, complimentary speaker cabinet IRs created by Tone Factor and York Audio, and controllable room size. With the ACS1, players have expansive options to deliver their tone on stage, in the studio, or practicing at home. Simple controls, stereo in and out, onboard presets, and MIDI support make the ACS1 an essential tool in a guitarist's arsenal. Players can also load in their own IRs and update firmware.

The ACS1 contains six amplifier models based on fan-favourite amps, each with its place in music history, and twelve cab IRs (Impulse Responses) designed by world-class designers to give you the best tonal representation possible. The stock IRs for the Fullerton, London, and Dartford amp models were custom engineered by David Hislop and Kenyon Reed at Tone Factor, while the stock IRs for the Red, Citrus, and Tread amp models were designed by Justin York at York Audio.

Amplifiers

The ACS1 can mix and match stereo amp and cab combinations. Want to run an AC30-style amp on the left and an Orange-style amp on the right? Or perhaps a 5150 flavoured amp in both channels but with two different cabs for a wider stereo sound? When running the ACS1 in stereo, one amp can be used through both channels, or these combinations can be run independently left and right if you choose, leading to powerful, unique amp tones. Simply press down on the Middle encoder to choose individual settings for L, R, or L+R combined. Amps can be mixed and matched with no phase/polarity issues as well.

Onboard models include:

Three Vintage Amp Models

Fullerton - Inspired by the classically bright and clear Fenderr Deluxe Reverb. Crisp clean tones with loads of headroom that players have come to love over the years.
London - Inspired by a 1962 Marshallr Bluesbreaker with a harmonically rich, valve-driven breakup. Articulate and sensitive response.
Dartford - Inspired by the legendary jangly high-end tones from a 1960s Voxr AC30 with all the bite and chime from the British Invasion.

Three High Gain Amp Models

Red: Inspired by the distinctively raw and punchy Peaveyr 5150, producing heavy, aggressive modern metal and hard rock sounds. Powerful and saturated with a tight low end, strong midrange, and a bright, cutting high end.
Citrus: Inspired by the warm, rich, and harmonically complex Oranger Rockerverb. Classic British gain with a creamy midrange and punchy lows. Maintains clarity and definition across its entire tonal spectrum, even at high-gain settings.
Tread: Inspired by the world-famous Mesa Boogier Dual Rectifier with massive amounts of in-your-face gain. Versatile enough to be favoured by guitarists in genres from hard rock, punk, metal, and more, Tread offers up plenty of saturation that's heavy and ready to cut through the mix.

Cabinet IRs

The ACS1 includes six IRs custom-engineered by David Hislop and Kenyon Reed at Tone Factor and six by Justin York of York Audio. Each IR has been created with vintage and modern amps to deliver the best tonal representation possible.

Additional ACS1 Settings/Features:

Primary Controls

Volume, gain, and room make up the top three knobs. Volume and gain work together, as gain is increased and made louder, volume can be turned down to compensate.

Room The ACS1 has three different types of reverb effects:

Room - Simulates the size of the room that your amp and cabinet are in. At zero, it would resemble tracking your amp in an isolated environment with no reverb. At max would emulate a natural-sounding, large studio environment.

Hall - Simulates the acoustics of a large, live sound space.

Spring - Simulates spring reverb tanks found in tube amps.

Increase the room size or amount of reverb by adjusting the Room knob. The further clockwise you go, the bigger the room. Decay control can be adjusted for room in the Global Sound menu.

Bass/Mid/Treble EQ

Bass, mid, and treble control are adjustable on the home screen with the use of the encoder knobs. The left knob controls bass, the middle is mids, and the right is treble. This simple EQ control has clear visual feedback and can be used to adjust levels on the L, R, and L+R channels.

Noise Gate

A noise gate can be applied and adjusted within the navigation menu, which can be especially helpful when playing with the high-gain amp models.

Amp EQ

Presence and resonance controls are available within Amp EQ Settings in the menu, giving you even more control of your amp tone.

(Access the settings for noise gate, Amp EQ, and more by clicking the bottom left and middle encoder knobs simultaneously).

Bypass IRs or Amps

Cab IRs as well as amp models can both be bypassed with the ACS1, making it more flexible for ampless rigs that still have physical cabs, and vice versa.

Notes: The D1 MKII is a feature-packed, high-fidelity all-in-one delay pedal with six algorithms for players to choose from: Digital, Mod, Vintage, Dual, Reverse, and Grain. The D1 can create inspirational delay trails ranging from dreamlike and bizarre, to rhythmic and clear, to warm and analogue sounding.

Program Controls:
Each program can be fully customized to your taste and playing style with the left encoder knob, which controls six parameters on all programs of the D1: Depth, Rate, Shape, Age, Tone, and Spread.

The Right encoder knob adjusts BPM, Swell, and Tap Division. BPM can also be set via the tap tempo switch or MIDI. Some programs will have additional options. See the manual for details.

Programs:
Digital - The Digital delay program offers a clean and crystal-clear delay that is perfect for rhythmic guitar parts where ultra-defined echoes are desired.

Mod - The Mod delay program has unique modulation LFOs applied to random repeats and run at multiple rates to create unpredictable pitch modulation. This results in unique sounding repeats perfect for warping minds and scattering trains of thought.

Vintage - The Vintage program allows for analogue tape delay-inspired tones to be achieved with complex filtering applied to the repeats. Use the tone knob at low settings for darker filtering and at higher settings to roll off the low end.

Dual - The Dual program employs two delays, one in each channel and both with different repeat subdivisions. The user has complete control over these subdivisions for both the L and the R channel, and can also choose to run their channel feedback in parallel, ping pong, or series. This effect can leave some jaw dropping trails, especially in stereo.

Reverse - The Reverse program reads the delay memory backward creating a unique delay repeat character known as a reverse delay. Select whether your repeats stay always reversed, or follow an analogue reverse feedback system where the repeats flip flop.

Grain - The Grain program can be as smooth, choppy, glitchy, or flowy as you want it to be, and for users who may want to try their hand at experimenting a little, this will be the perfect program for them to explore. The grain trails can be adjusted to short staccato sounding glitches, or opened up for full immersion. It's a whole new world, but the player is still firmly in control.

Presets:
The D1 can save up to 128 onboard presets, which can be held in a preset bank made accessible by tapping down on the bottom left and bottom middle knobs simultaneously. Presets 0-9 are divided into Banks A, B, and C. Select a bank while in the preset menu. Bank A will cycle through presets 0-2, Bank B will cycle through presets 3-5, and Bank C will cycle through presets 6-9. Presets 10-128 can be accessed through manual selection or MIDI.

Notes: The M1 MKII is a stereo, all-in-one modulation pedal featuring six studio-grade programs based on fan-favourite modulation tones: Chorus, Phaser, Tremolo, Vibrato, Rotary, and Filter. A sound explorer's delight, the M1 features a dedicated lo-fi knob allowing you to mix various lo-fi parameters to every program. From the swirling, lush sounds of the 80's to more subtle applications that give your tone a distinct flair, this is a hallmark for all kinds of modulation fans, offering limitless creative potential.


Program Controls
Each program can be fully customized to your taste and playing style with the left encoder knob for features like effect type, BPM, wave shape, and more. Refer to the manual for program-specific features.

Programs
Chorus - From subtle chorus to vibrant and lush tri-chorus that will instantly teleport you to the 80s. Type I is a traditional chorus great for tight smooth chorus tones. Type II finds its roots in the classic tri-chorus effect running three chorus units in parallel for a lush multi-dimensional chorus. Type III transforms into a sweeping, vintage-style flanger, a welcome addition for modulation fans.

Phaser - Classic 70s phaser sounds we all know and love, with added features that you wouldn't expect. Similar to the Lillian, Type I is a 2-stage Phaser that produces a single notch to the classic mild phaser. Type II is a 4-stage model producing 2 notches for a stronger effect. Type III is a phaser modelled after the unique tuning and LFO shape found in a Uni-Vibe.

Tremolo - This program emulates a tremolo with three algorithms containing all the bells, whistles, and stereo spread options. Type I is excellent for traditional sounds similar to optical and bias tremolos that raise and lower the entire frequency range - similar to the Monument in standard mode. Type II is a warm and cozy harmonic tremolo - similar to the Monument in harmonic mode. This unique sound is formed by raising and lowering your high and low frequencies opposite each other. Type III offers several predefined patterns for rhythmic sequenced pulsing tremolo.

Vibrato - Make good parts great with detuned, warbly, and vintage sounds that harken back to the 60s. Type I "Traditional" focuses on standard vibrato sounds. Old record players inspire Type II "Vinyl" with classic RPMs on the rate knob and some noise character you'd find in your dad's old dusty Foreigner LPs. The rate knob can select 33rpm, 45rpm, and 78rpm speeds in this mode. Type III "Tape" is our take on the wow and flutter pitch characters found in old tape players. Warm and charming with a hint of nostalgia.

Rotary - Because you can't fit a Leslie speaker on your pedalboard, Type I aims for that traditional watery sound of a well-oiled Leslie speaker. Type II only spins the horn but still plays the sound out of the drum. Type III only spins the drum but still plays sound from the horn. Further fine-tune the drum sounds by experimenting with mic distance in the program controls.

Filter - Add tone-shaping movement to your signal with different modulated filters. Type I is a lowpass filter good for modulated darker tones. Type II is a highpass filter used to creatively modulate your low frequencies. Type III is a bandpass filter forming a sliding "window" of frequencies.

Resonance, envelope speed, and release can all be adjusted on Filter mode, the result being dynamic sweeping sounds and an expressive touch, commonly heard in blues or funk. This program can be easily run as an Envelope Follower type filter.

Lo-Fi Controls:
The M1 Features 6 Lo-Fi-type global controls to make your High-Fidelity modulation machine sound...not so High-Fidelity. Using the Right encoder knob, take your signal back in time and degrade it to sound like tech of yesteryear then use the Lo-Fi knob to adjust in the overall mix.

Env: Envelope allows you to dynamically open the tone based on how hard you play.
Drive: Drive offers a crunchy analogue-style drive to be added to your signal simulating the warm sound of overdriven analogue circuitry.
Space: Space allows you to add some reverb to your modulation chain. Turn to minimum to disengage and turn up to increase mix and decay.
Age: Age engages a complex set of filters used to simulate the limited bandwidth of vintage audio players and recording equipment. From modern, full-frequency at minimum to subtle low-fidelity tones in lower positions and old, thin AM radio sounds in higher positions.
Noise: Noise adds lo-fi analogue inspired noise to your signal.
Warble: Warble manipulates the main LFO wave shape causing it to deform making interesting and less predictable modulation.

Presets
The M1 can save up to 128 onboard presets, which can be held in a preset bank made accessible by tapping down on the bottom left and bottom middle knobs simultaneously. Presets 0-9 are divided into Banks A, B, and C. Select a bank while in the preset menu. Bank A will cycle through presets 0-2, Bank B will cycle through presets 3-5, and Bank C will cycle through presets 6-9. Presets 10-128 can be accessed through manual selection or MIDI.

Notes: The R1 MKII is an extremely powerful and versatile multi-function reverb that can go from intimate, small-room type subtle reverbs to huge, experimental euphoria. With six distinct programs based on fan-favourite reverb sounds that have been built from the ground up, players of all styles and genres will be able to find eternal inspiration with the R1.

Program Controls

Each program can be fully customized to your taste and playing style with the left encoder knob for features like modulation rate, ducking, and more. Refer to the manual for program specific features.

The R1 MKII includes a unique Ducking/Swelling control that modifies the reverb's behavior. Higher settings increase the swelling effect, making it more prominent, while lower settings enhance the ducking effect, helping to maintain a clear and focused mix.

The Right encoder knob adjusts parameters like reverb EQ and room size. See the manual for details.

Programs:
Spring: The Spring program emulates an excited spring reverb commonly found in tube amps with loads of transducing drip. Easily go from subtle to full-on surf rock. Experiment with the decay knob to get more than average amounts of reverb not found in traditional amp spring reverb tanks.
Hall: The Hall program provides the acoustics of large live sound spaces like concert halls to arenas. Longer decays result in a massive wash of ambiance.
Plate: The Plate program emulates a smooth analogue plate reverb with nice even diffusion for the classic plate sound that you know and love.
BFR: BFR is a no holds barred, big, f____, reverb. This is more than a giant arena reverb. It's a hall-esque reverb with rich and lush decay in a vast cavern filled with choirs of angels.
Refract: The RFRCT program allows for lovely, charming, and glitch-like textures hovering over a controllable amount of diffusion. The Rate controls on RFRCT set how often new grains trigger, while Depth controls the amount of modulation applied to the grains. The Time control sets the delay time of the grains, and the size control sets the size of the grains being pulled from the buffer. The diffuse control allows you to take the grains from super dry and stuttery to washed out in a reverb mix.
Air: The Air program offers a larger diffused reverb with a shimmer, as well as a distinct clarity to its decay. Adjust the shimmer control to really lean into that high-octave sound that ambient style artists have come to love over the decades. Explore slow-building complimentary sounds that don't get in the way of your playing.

Presets
The R1 can save up to 128 onboard presets, which can be held in a preset bank made accessible by tapping down on the bottom left and bottom middle knobs simultaneously. Presets 0-9 are divided into Banks A, B, and C. Select a bank while in the preset menu. Bank A will cycle through presets 0-2, Bank B will cycle through presets 3-5, and Bank C will cycle through presets 6-9. Presets 10-128 can be accessed through manual selection or MIDI.

Notes: Distortion and reverb meet in this unique pedal, sporting a joystick to tweak the sound and the option to flip the order of the two effects in the signal chain. Simple, quirky and effective.

Supplier's Notes:
Walrus Audio give you the two most quintessential effects that yield unruly amounts of power and influence to an instrumentalist: reverb and distortion. They have been harnessed and woven together for an eternity of ethereal power with The Melee: Wall of Noise. The Melee unapologetically uses a joystick to meld reverb and distortion into one massive blaze of sound. With the flip of the order switch, run the distortion into the reverb or reverb into distortion; signal chain is your call now. For the explorer, the Melee can run one of three different reverb programs Ambient, Octave, and Reverse.

In a less is more approach, Walrus Audio have intentionally decided on controls that are fun to use and will inspire a wealth of creative output. Use the joystick to control the amount of distortion by moving it up and down. Moving the joystick left and right will adjust your reverb mix. The tone and decay toggles have low, medium, and high settings. Modulation can be added to the wet signal by holding down the bypass switch and moving the decay toggle. The left position is no modulation, the middle is a slight modulation, and the right is a high modulation.

Algorithms

The Melee is equipped with three different reverb programs, which can be changed by simultaneously pressing the bypass and sustain stomp switches. Experiment with the order toggle switch to hear how differently these all react in front and after the distortion!

Ambient Reverb (Pink LED) - Huge reverb capable of massive trails and engulfing your chords into an angry wash of sound. Great for soaring melodic lines or shoegaze-driven chord progressions.
Octave Down Reverb (Yellow LED) - Similar to the Dark mode in the Slo, you'll find an eerie lower octave hovering in the reverb trail for a nice and dark atmospheric touch.
Reverse Reverb with Feedback (Blue LED) - Add reversed reverb trails back into your signal, create gentle melodies or push into reverse feedback overload. Big, slow, and sad chords love to hang out here.

Momentary

Press and hold the sustain switch to ramp up the reverb trails. Release and the trails will ramp back down to where the decay switch is currently set. The sustain switch can also latch in all three programs. Press and release the Sustain switch to capture and sustain the current reverb decay for long pad-like sounds in your wet mix. Press again to release the latch, and the reverb trail will taper off based on the position of the decay knob.

Specs

The Melee comes coated in a glossy neon pink enclosure with white, yellow, and green inks with art by
David Huttner.
The die-cast enclosure's exact size is 3.62" x 4.79" x 3.14" (including joystick height).
Three bypass modes, DSP, DSP + True, True Bypass
Power requirements are 9VDC, centre negative (200mA minimum).

Like the Iguana that's malleable to its environment, blending into its surroundings for harmonious balance or standing out with vibrant confidence, the Polychrome Flanger is a uniquely colourful tool for adding modulated textures to songs.

The Polychrome Flanger is a true bypass, all analogue Flanger pulling in familiar layout controls from the Julia and Lillian.
Dial in a wealth of colourful flange with the D-F-V blend knob and the shape and voice switches.
The Shape Switch lets you select from sine, triangle, or random LFO wave to modulate the delay line

The Voice Switch lets you select between two voices for the flanging effect.
In the down position, the flanger is more traditional and full frequency.
In the up position, you get a more complex and notched flange effect with less low end.

Like the other members of the Walrus Audio modulation family, the Polychrome has a blend knob. The D-F-V (Dry, Flange, Vibrato) knob lets you blend the dry and delayed signal from full dry at minimum (no effect), to traditional flange at noon to full pitch vibrato at maximum. Don't sleep on the vibrato sounds in the Polychrome.
Set the D-F-V knob to maximum, feedback to a minimum, and the voice switch up for some unique pitch vibrato.

Top mounted input, output, and power jacks as well as soft switch relay bypassing make the Polychrome fit well on your board and ensure smooth operation for years to come.

Global Controls


Space Knob: Space adds a delightfully charming reverb to your affected signal. Use this knob to modify the mix and decay of the reverb. Go from smaller room sounds to a huge, diffused ambient reverb at maximum settings. It's lush and complimentary, and adding it in with the other effects will put you squarely in dreamscape territory.


Tone Knob: The Tone parameter controls the cutoff of a synth-style resonant low pass filter, allowing you to shape the tone of the effect output.


Series and Parallel: In series, effects will feed into each other in the order of Chorus > Delay > Grain > Output.


In parallel, all of the effect outputs on Chorus, Delay, and Grain are summed together and do not feed into each other. The top row of knobs will act as level controls, and the user can control the level of each effect.


The Mix/Dry parameter controls the mix of wet and dry signal in series mode and dry level in parallel mode.

Grain Controls


The featured Grain effect features two 'flavours' of operation:


Grain Cloud: This mode triggers small samples (grains) randomly from your playing, which gives you unpredictable, yet charming glitchy texture for your sound. The X knob controls the length of time between grains, so you can go from dense clusters to sparse accents.


Phrase Sample: This mode triggers grains rhythmically from your playing. Initial peaks in your playing are detected and grains are played back starting at these peaks, creating a rhythmic and intentional effect. The X knob controls the tempo at which the samples will be played back. Turning the X knob to the minimum position will sync the Phrase Sample time to the Delay time so that repeated grains are in time with the Delay repeats.


The Grain effect also features 5 playback modes that dictate different ways the grain samples are projected.


x1: Normal
x2: Double-speed and +1 octave
x.5: Half-speed and -1 octave
REV: Reverse playback
RNDM: Randomized combination of the previous four modes.


Delay Controls

The delay effect is a full, clean digital delay that offers repeats for up to two seconds. Use the time knob to control the time between delays as well as the feedback knob to control the amount of delays. The TAP/OSC switch on the bottom right of the pedal can also be used to control the delay effect via tap tempo, or when held down will ramp up the feedback and cause the delay to oscillate.

Subdivisions

Delay trails can be projected in three subdivision modes:

Quarter Note
Dotted Eighth Note
Eighth Note

Chorus Controls

The Chorus effect offers two modes:
Tri Chorus: A multi-dimensional chorus favourite. Lush, complex, modulated sounds combining three voices for a full, vibrant sound.

Stereo Chorus: This mode is a classic chorus effect but with the modulation of the chorus being offset 180 degrees to the right channel to achieve the stereo width effect.


Other Features

Three on-board presets (red, green, blue) plus a live mode (white).
TRS MIDI 1/8" in and thru ports for MIDI control.
USB-C port included for future firmware updates.

Notes: Unearth the Walrus Audio Silt Harmonic Fuzz, a collaborative creation with tube expert Jim Hagerman.

Wielding an internal pre-amp tube, the Silt is a two-in-one fuzz that creates massively rich fuzz tones perfect for chords and rhythmic parts or with the press of a switch, adds uniquely harmonic overtones to the signal before hitting the tube. Crafted specifically for those seeking a harmonically rich fuzz experience, the Silt boasts an analogue circuit with the distinctive warmth of a 12AU7 tube as its drive section, letting you explore a unique and wild sonic landscape.

Main Features:

1. 12AU7 Tube Drive

The Silt's 12AU7 tube section drives the warm, bone-rattling fuzz. We unearthed this sonic fossil to encase your sound in an amber warmth, while still providing the grit, growl, and harmonically complex textures that only a tube-driven fuzz can provide.

2. Harmonic Mode

Harmonic Mode acts as a frequency doubler before the drive section of the pedal. This produces crispy, octave-like sounds, lending a unique edge to your lead tones. Try this with your guitar tone knob rolled off.

3. Contour Control for Precision Tone Sculpting

Refine your fuzz tones with the precision of the Contour control to achieve a wide spectrum of timbres.

Toggle between highpass, flat, and lowpass curves in the pre-tube EQ stage, like uncovering layers of sonic strata. Especially helpful when switching between different styles of pickups. Whether you're chasing searing leads or wooley rhythm, the Silt adapts to your style with roaring precision.

4. Designed for Operation at 9v-12v for Plenty of Gain

Supercharge your fuzz experience by operating the Silt anywhere between 9v and 12v. Running the pedal at 12v will give you an extra gain boost, letting you push the primal boundaries of fuzz to deliver the searing tones you've been searching for.

5. True Bypass Circuit

Maintain the integrity of your original tone with the relay bypass circuit. When disengaged, the Silt ensures your signal remains pure, allowing your guitar's natural voice to shine through undisturbed.

Controls:

Volume: Control the output volume level of the pedal.
Tone: Sculpt your output tone with a lowpass/highpass tilt tone control.
Gain: Control the input gain into the fuzz circuit, from subtle, distortion-like crunch to full-throttle fuzz.
Contour: Toggle between highpass, flat, and lowpass curves in the pre-tube EQ stage.
Bypass Switch: Enable or disable the effect with the relay bypass switch, preserving your original signal when the Silt is not in use.
Harmonic Switch: Activate or deactivate the frequency doubler circuit before the clipping stages, infusing your sounds with octave-like textures for a unique sonic edge.

Notes: The Voyager MKII is a mid-focused overdrive/preamp that contains all the mythical magic from the original Voyager and adds a wealth of features not seen before in a Klon-style pedal.

From its lowest to highest settings, the Voyager provides a uniquely superb amount of clarity to any playing style. At lower gain settings, it brightens the signal and adds clarity to each note. With the gain turned up, the Voyager transforms into a thick overdrive, providing depth to chorded playing while retaining the clarity needed to break through solos.

The Voyager MKII breaks out of the traditional Centaur three-knob topography by adding a foot-switchable parametric mid-frequency EQ with a boost/cut range of +/-12dB. The Freq (Frequency) knob then controls the centre frequency of where the Mid knob is set, giving a range of 250Hz-2kHz. Great for accommodating any guitar and pickup combination and tailoring your tone to your own style of playing.

Further customize the Voyager's sound with the five-way rotary switch:
1. Classic 1N34A Germanium Diodes (most compressed). This is the original Voyager sound.
2. Classic 1N34A Germanium Diodes with bass boost (trust us).
3. Symmetric Silicon Diodes (more open and dynamic).
4. Asymmetric Silicon Diodes (least compressed, open & driven).
5. Asymmetric Silicon Diodes with bass boost (least compressed, open & driven with a bass boost.)

Think of each position as a different "flavour" of the pedal. Fine-tune each of these modes with the Mid/Freq EQ for a near-infinite supply of gain options.
