Notes: Produces volume and reverse swells, backward tape sounds, artificially short staccato notes and bowed instrument effects!

The circa-1980 Electro-Harmonix Attack Decay is a sought after prize among vintage pedal aficionados. Originally called a Tape Reverse Simulator, it's known for producing volume and reverse swells, backward tape sounds, artificially short staccato notes and bowed instrument effects. The freshly designed EHX Attack Decay reinterprets the classic and keeps its cool factor, but adds some modern features for convenience and enhanced functionality.

It can produce a single volume envelope like the original, or, with Poly engaged, put separate volume envelopes on each note you play. The built-in Harmonix fuzz is now a fully controllable distortion with gain, tone and volume controls. The effects loop allows the musician or sound designer to place the volume envelope onto whatever signal is present at the Return jack. Expression pedal/CV input and three user presets give the user total control over their Attack Decay!

Volume envelope manipulation with adjustable Attack and Decay times
Mono mode: one volume envelope at a time, the envelope resets when you play a new note
Poly mode: gives each note you play its own envelope
Built-in, fully adjustable, Harmonix fuzz enhances the volume envelope effect and produces bowed instrument sounds
Built-in effects loop allows for your own pedals to be inserted onto the volume envelope
Expression pedal or CV control over every knob on the Attack Decay
Save and recall up to three presets

Notes: Get lush EHX vibrato and chorus in a compact, pedalboard friendly package with unique control options!

No one does bucket-brigade effects like Electro-Harmonix and with the Eddy you get lush EHX vibrato and chorus in a compact, pedalboard friendly package with unique control options.

The Eddy gives you envelope and expression pedal control over modulation rate and depth. That means you can control either with your playing dynamics. Plus, if you plug in an EXP pedal, you can use it to control the rate or depth at the same time.

The Eddy also features LFO shape warping which can transform the shape of the modulation from a standard sine wave to something totally asymmetric. Plus, the pedal's tone control lets you make the sound brighter or darker.

EHX Founder, Mike Matthews, says: EHX's long history in creating bucket-brigade based pedals goes all the way back to the Electric Mistress Flanger, the Memory Man Analog Delay and the Clone Theory Chorus/Vibrato. The new Eddy springboards off that rich heritage and adds modern control to classic sounds.

Notes: A modern fuzz with old school roots and pays homage to one of the ways that early, distorted guitar and bass sounds were made!

The Ripped Speaker is a modern fuzz with old school roots and pays homage to one of the ways that early, distorted guitar and bass sounds were made. At low fuzz settings the pedal emulates the lo-fi distortion sounds of yesteryear, the kinds of sounds created by a razor blade applied to a speaker cone, a loose tube or a faulty channel on a recording console. When you crank the fuzz up the sound is transformed. It's modern and monumental with a searing, fully saturated, fuzz tone.

The Ripped Speaker's RIP knob is a bias control which sets the amount of clipping at the top and bottom of the signal wave form. It adds a lot of versatility and lets you tailor the character of the fuzz. Noon is neutral, a position where the fuzz is perfectly biased... fat, with a great low end and top end bite without being harsh. As you turn the knob clockwise the pedal produces a hard gating effect and the signal sputters and chokes. It's great for creating a dying battery effect. Turning the knob CCW produces yet a different style of fuzz with a smoother gating effect where the signal fades out quickly.

The Ripped Speaker's TONE control is active and delivers a tilt-shift type EQ. That means at noon the EQ is flat. As you turn the knob counter-clockwise the frequency response gets darker with more pronounced lows and less highs. Going clockwise yields a brighter tone with more highs and rolled back lows.

The Ripped Speaker features true bypass switching, comes equipped with a 9 Volt battery and accepts a standard EHX 9 Volt power supply.

Notes: An ultra-compact workhorse that's perfect as part of a portable guitar rig, or as an emergency backup should your main amp break down.

The 15Watt Howitzer guitar amp/preamp is an ultra-compact workhorse that's perfect as part of a portable guitar rig, or as an emergency backup and gig saver should your main amp break down. It's super flexible, like a musical chameleon, and depending on the gear you use and your style, will fit in the broadest range of genres.

The 15Watt Howitzer's Volume and Gain controls let you go as clean or as crunchy as you want while the Bass, Mid and Treble knobs provide plentiful tone shaping. Its FX Loop gives you the option of putting effects like reverb and delay after the preamp. Of course you can still run your guitar straight into pedals and then right into the 15Watt Howitzer's input jack.

EHX's Founder, Mike Matthews, said: Dig it! The sandwich-sized 15Watt Howitzer is perfect as part of a compact guitar rig or backup. But the thing I dig the most, is the tone that emanates from the Howitzer. It's super versatile and depending on what kind of setup you're running fits into any style that's your bag!

Notes: A sophisticated noise gate that can tame a single pedal or an entire effects loop! The Silencer's three-control layout provides precise fine-tuning to fit your system, axe and playing style. Threshold adjusts how much level is required to open the noise gate and allow a signal to pass thru. Reduction regulated the degree to which the gated signal is reduced and is variable between -70dB and +4dB. Release controls how long the gate remains open after the signal drops below the Threshold. Release time is variable between 8ms and 4 seconds.

I/O includes 1/4" Input, Output, Send and Return jacks. The footswitch selects whether The Silencer is engaged or in bypass mode; buffered bypass allows the effects loop to remain in your signal path when the gate is bypassed. A built-in AC jack accepts a standard power supply like the EHX 9.6DC unit (optional) and the pedal comes with a 9V battery.

Conquer noise with The Silencer!

Notes: The EHX Bass Mono Synth transforms your bass into eleven great sounding synthesizers... from vintage synth emulations to thick, stacked voices to deep pulsing sounds and more.

Its intuitive layout makes it easy to use and easy to dial in good sounds quickly. DRY controls the volume of your dry bass signal at the Synth Output. SYNTH controls the volume of the Synthesizer sound at the Synth Output. Used together they let you create just the right mix. The SENS control, short for sensitivity, adjusts how your playing dynamics trigger the synthesizer and allows you to fine tune the way the pedal responds to your bass rig and playing style.

With the CTRL knob you can adjust a key parameter for each of the eleven synth types. It varies depending on the preset and provides more tweakability for customizing your sound. There’s also an EXP input which lets you control an entirely different parameter in real-time with an expression pedal!

Using the built-in Preset footswitch, a user customizable preset for each of the eleven synth sounds can be created, saved and recalled. The factory presets are also easy to restore should you wish to.

From lush, warm sounds to sharp, percussive stabs, the Bass Mono Synth puts a collection of cool bass synths at your fingertips.

Notes: Analogue delay with extensive controls and tap tempo all in an affordable package!

The EHX Deluxe Memory Boy Analog Delay's Quality ICs deliver warm and organic analog tones while "tap tempo" allows you to always be in sync with the groove.

Notes: With 11 reverb types and a ton of "hidden" functionality, the Electro-Harmonix Oceans 11 reverb pedal could be your new go-to reverb pedal. You can tap into classic tones like hall, plate, and spring reverbs, including a brand-new spring reverb algorithm that sounds gloriously complex and rich - you can even double-tap the footswitch to "crash" the spring reverb. And you'll be able to cover a huge range of modern tones with a variety of modulated reverbs, shimmer reverb, reverse reverb, and more. A mode switch offers access to variations on many of the 11 reverb types. Complete with an infinite reverb mode for freeze-style effects, there is vast creative potential in the Electro-Harmonix Oceans 11 reverb pedal.

Reverb types:

Hall - rich and full sound of a grand concert hall
Spring - brand-new tube spring reverb emulation
Plate - lush and warm plate reverb
Reverse - each note fades in backwards
Echo - recirculates echoes through the plate reverb algorithm
Trem - hall reverb plus tremolo
Mod - modulated reverb
Dyna - swells, gates, and ducks in response to your playing dynamics
Auto-Inf - auto-infinite reverb, triggers a wash of reverb with each new note or strum
Shim - shimmer reverb with an octave-shifted wash that blooms behind your core tone
Poly - polyphonic reverb with two pitch shifts operating on your pre-reverb guitar tone

Notes: Buzz. Beep and bloop. Get high on the lo-fi sounds of "old-school" games, toys and terminals!

The Mainframe provides sample rate reduction ranging from 48kHz to 110Hz. A little background... the sample rate is the number of times per second that a sample or snapshot of an analogue signal is taken. For example, CDs (remember them?) had a sample rate of 44.1kHz which means that the original analogue signal is sampled 44,100 times per second.

The sample rate defines the frequency range that can be reproduced while maintaining good fidelity. When the sample rate is reduced the quality of the audio is degraded and aliasing occurs. Aliasing means audible artifacts created when higher frequencies are sampled at an inadequate rate and the result is distortion. The Mainframe's sample rate range is wide enough to take you from sounds that are quite pristine to sounds that are unrecognizable when compared to the input signal.

It also provides bit crushing ranging from 24-bit to 1-bit. What does that mean? Bit crushing is bit depth reduction. Back to the CD example... CDs used a 16-bit bit depth meaning that each of its samples was represented by 16-bits of information. Higher bit depths can accurately represent a greater dynamic range while bit crushing increases the number of sampling errors and creatively degrades the sound to bring us back to those nasty "old school" sounds we love.

The Mainframe's selectable High/Low/Band-Pass filter lets the user shape the artifacts of the bit crushing and sample rate. Another very cool feature is its Sample Rate Tuning Mode where the pedal analyses your input signal in real-time and sets the sample rate to match the pitch of your signal, or a set interval above your signal. This allows you to set the sample rate to match the key of a song, or it will continually adjust the sample rate based on what you play!"

Notes: 30 fully polyphonic pitch-shifting options under 15 square inches!

Offering a total of 30 pitch shift options and expanded controls, the Pico Pitch Fork is the next evolution in pitch shifting from Electro-Harmonix. The original Pitch Fork has garnered praise from all styles of player at every level and the Pico Pitch Fork brings even more features to the celebrated pedal in an impossibly small package.

The Pico Pitch Fork features 10 pitch shift intervals and three modes of pitch-shifting - Up, Down and Dual. Dual mode features specially paired pitch shift intervals to allow for more musical effects.

Controls on the Pico Pitch Fork are simple and effective. SHIFT selects the Pitch Shift interval. BLEND sets the wet/dry blend of the output mix while VOL adjusts the overall output volume. SWEEP controls pitch bend sweep time when toggling between bypass and effect and back to create automatic whammy effects. The Pico Pitch Fork's footswitch can operate in two modes: Latching and Momentary. Latching turns the effect on with one footswitch press and off with another while Momentary turns the effect on only when the footswitch is being held for instant bursts of pitch-shifting pandemonium.

Notes: Celebrating the classic, shimmering flanger sounds of Andy Summers, the EHX Walking on the Moon is a tribute to the tones Andy employed while carving his niche in the early days of playing with the Police. Liquid flange effects that hint toward chorus with extra depth and nuance make Andy's sound one of the most coveted in all of the guitar universe.

"This beautiful shimmering which sort of made the sound more bigger and more glamourous - became a sort of characteristic of my guitar sound - A big part of my guitar sound at that time in The Police was the flange sound which we have here today in this great new pedal." - Andy Summers

The Andy Summers Walking on the Moon is an analogue flanger with a simple but powerful control set of RATE, RANGE, and COLOR. RATE sets the speed of modulation which ranges from slow, smooth filter sweeps to jittering vibrato. RANGE controls how narrow or wide the effect sweeps into the bass frequency range. The COLOR control effects the intensity of the flanger effect from subtle chorusing effects to classic jet woosh sounds. These three controls interact to create a wide breath of modulation effects.

Additionally, the Walking on the Moon includes a FILTER MATRIX which disengages the LFO from the flanger circuit, freezing the flanger giving a fixed filter effect, which can add chime or metallic overtones to your sound without the movement of a traditional modulation pedal. A DRY output allows you to split your dry signal from the effected signal.

Special Artist Edition graphics featuring Andy's signature adorn the chassis and a tribute Walking on the Moon poster with art by Laura Josephson is included with each pedal.

Notes: Electro-Harmonix has reissued their late-1970's era Op-Amp Big Muff Pi. Sometimes also referred to as the IC or V4 Big Muff, the original circuitry has been faithfully re-created while several practical enhancements have been added including a compact, die-cast chassis and true bypass switching.

According to Electro-Harmonix founder, Mike Matthews, "The Op-Amp Big Muff was popularized by the brilliant Billy Corgan who first used it on the Smashing Pumpkins' epic 1993 album Siamese Dream. After he was videotaped playing and talking about the reissue, Billy stated: "The magic's still in the box, I can still get what I'm looking for!"

The pedal relies on op-amps rather than transistors and three gain stages rather than four, to create its signature sound. It's a sound that's been described by noted Big Muff collector and historian, Kit Rae, as: "a huge, crushing Big Muff sound with more crunch...great for grungy, wall-of-sound distortion, heavy rhythm playing and heavy leads."

The Op-Amp Big Muff Pi features standard controls: Sustain, Tone and Volume, plus a Tone switch for bypassing the tone circuit. It comes equipped with a 9V battery or can be powered by an optional 9-volt AC adapter.

Notes: The Pitch Forkr+ features two independent pitch shifting engines with full control over each. Both will transpose your pitch up or down over a +/- three octave range and detune +/-99 cents. With rock solid tracking, an organic, musical tone and extensive control, it's your ultimate harmonizer.

Notes: The Mod 11 is packed with 11 different modulation effects that range from classic to exotic plus advanced functionality all in a compact pedal. It gives you access to powerful yet intuitive "hidden" parameters accessible through its Secondary Knob Mode which let you take even greater control over its effects.

The Mod 11's modulation effects are:

1. TREM: Tremolo modulates your signal's volume. Selectable modes allow your playing envelope to control modulation rate or depth.
2. HARM: Harmonic tremolo. The signal is split into high and low frequency bands and modulated between the two. Selectable modes allow your playing envelope to control modulation rate or depth.
3. VIBR: Vibrato modulates your instrument's pitch. Selectable modes allow your playing envelope to control modulation rate or depth.
4. UNI: pays homage to the classic Univiber. Includes "Chorus" and "Vibrato" modes plus added overdrive
5. CHORUS: Warbling, doubling, chorus effect like the EHX Small Clone. Extra modes include tri-chorus and bass chorus effects
6. ROTARY: Rotary speaker cabinet simulation. Extra functionality includes overdrive plus envelope control over rotation speed
7. FLANGE: Flanging with modes for both additive and subtractive flanger. Multiple LFO shapes, including envelope follower
8. TZF: Through Zero Flanger. A flanger effect that crosses through the "zero point" of the sweep where the modulated delayed signal meets back with the dry signal. Modes for both additive and subtractive flanger, plus barber-pole flanger
9. PHASE: Choose from 4, 6, or 8 stage phaser. Multiple LFO shapes including envelope follower
10. PITCH: Modulated pitch shifter. Select your main pitch shift and modulate around it. Extra functionality includes a dry blend and stepped pitch modes
11. FILT: Modulated filter effects like those on classic analogue synths. Low Pass, High Pass and Band Pass. Multiple LFO shapes available including a Q-Tron style envelope follower

The Mod 11's Momentary Mode lets you seamlessly switch in and out of effects mode for quick accents. It also features Tap Tempo controllable via the built-in footswitch or an external one. The Mod 11 is modulation with warp drive!

Notes: The EHX 5MM Guitar Power Amplifier is a pocket-sized power amp that’s a great alternative to a traditional guitar amplifier. It’s super portable and perfect in playing situations where a high-powered amp is not required… like when you’re mic’d on stage, in the studio or as a backup. It produces 2.5 watts so one of the cool things about it is that it doesn’t take much to start getting some nice drive and saturation. Plus, it can be connected directly to any 8 O – 16 O speaker cabinet.

The 5MM is complete simplicity. It features a Volume control and a Bright switch which, when engaged, adds presence to the signal. Since it is a power amp, a preamp, overdrive pedal and, or an EQ in front of it will really let you dial in your tone, but it can be used by itself. The 5MM Power Amplifier also comes equipped with its own power supply.

Notes: Delivers overdrive and distortion with impact, and the modern player in mind!

The EHX OD Glove provides a rich, overtone laden sound that doesn't get muddy. Responsive controls that take you from sparkling, clean boost through brown crunch and all the way to thick, saturated hi-gain.

Notes: The Pitch Fork transposes an instrument's pitch over a +/- three octave range and features three modes which allow the pitch to be transposed up, down or both, simultaneously. The pitch shift amount can be set to a fixed interval or continuously varied by an expression pedal or control voltage.

The controls are straightforward and intuitive. An 11-position Shift switch selects the maximum transposition interval ranging from D (Detune), a shift of 17 cents, through Minor 2nd, Major 2nd, Major 3rd, Perfect 4th, Perfect 5th, Major 6th, Minor 7th, 1 Octave, 2 Octaves and 3 Octaves. A three position toggle switch controls whether the pitch is transposed up, down or both. In Dual mode, two pitch-shifted signals are output. One follows the shift knob as if in the Up position while the other creates a harmony. Dual Mode settings include M3 up + P5 up, P5 up + 1 Oct down, 1 Oct up + 1 Oct down and many others. A Blend knob controls the mix of the dry signal and the effected signal, and an EXP jack enables the player to control pitch and glissando with an expression pedal.

The Latch button selects Latch or Momentary mode which affects how the footswitch and EXP input behave. In Latch mode, the footswitch toggles between effect on and buffered bypass each time it's pressed and the EXP input continuously varies pitch. In Momentary mode the effect is only on while the footswitch is depressed and when it is released the Pitch Fork goes into bypass.

In Latch mode the EXP input controls pitch shift amount, ranging from unity to the interval set by the Shift knob, and pitch varies continuously throughout the expression pedal's range. In Momentary mode the EXP input controls glissando rate for the Pitch Fork's footswitch. When the bypass footswitch is pressed, the Pitch Fork jumps from bypass to the interval set by the Shift knob. The amount of time it takes to reach that new note is the glissando rate. When the footswitch is released the pitch will return to unity at the same rate. That glissando time can vary between 4 milliseconds to two seconds depending on the heel/toe position of the expression pedal. The default glissando rate is 60 milliseconds when nothing is plugged into the EXP input.

The Pitch Fork comes equipped with an EHX 9.6DC-200mA power supply and also runs on a 9Volt battery.

Notes: Compact multi-effect pedal combining the award-winning Soul Food Overdrive and Holy Grail Max Reverb!

The EHX Turnip Greens is a multi-effect pedal that combines the Soul Food Overdrive and Holy Grail Max Reverb.

The Soul Food delivers transparent sounds starting with clean boost and progressing all the way to intense overdrive. It's equally adept at adding punch to a player's tone, pushing an amp into saturation or in front of other dirt pedals driving them into new worlds of distortion.

The Holy Grail Max provides four carefully crafted reverbs: Spring, Hall, Plate and Reverse. A newly designed analog wet/dry control yields a constant volume curve as the Blend knob is turned from fully dry to fully wet, while also keeping the dry signal analog through the pedal.

A toggle effect-order switch, located in the middle of the Turnip Greens, selects whether the overdrive or reverb is first in the effects chain. Send and Return jacks let the player insert effects into the signal path between the two.

The Turnip Greens features an internal switch that lets the player select between true bypass or buffered bypass for the Soul Food section.

Notes: Designed in collaboration with JHS, the Lizard King is an octave fuzz pedal for bass which builds on the success of the guitar-focussed Lizard Queen. Dynamically responsive fixed gain fuzz can be blended from fully wet to dry, while octave tone can be blended separately.

Supplier's Notes:
Octave Fuzz for bass and beyond!

Make way for the new heir to the octave fuzz throne, the Lizard King from Electro-Harmonix. Directly inspired by the EHX x JHS collaboration released in 2023, the Lizard King takes the gnarly and responsive octave fuzz circuit from the Lizard Queen and optimizes it for bass and beyond. With updated tone controls and a new Blend knob, the bass's fundamental tone and low-end is preserved while the top-end of the fuzz tone is shaped to fit or dominate any mix!

The EHX Lizard King is a fixed-gain fuzz that is dynamically responsive. Adjustments to your instruments volume affects the amount of fuzz. Lower instrument volumes create a clear, fuzzy overdrive, while full instrument volume sends the gain over the top for ripping riff and searing solo tones. The familiar VOLUME and OCTAVE knobs control overall output and octave blend volume respectively. New to the Lizard King, the BLEND knob sets the mix between your clean and fuzz tones to create the perfect balance of fuzz while retaining your bass's attack and low-end. The TONE knob is a low pass filter that rolls off the highs, while the SUN/SHADOW switch further enhances the tone of the octave fuzz and clean tones. SUN boosts the octave fuzz with a more driving midrange, and the clean tone accessed by the BLEND knob has more treble and bass frequencies. When the switch is set to SHADOW, the clean tone is unchanged, and fuzz tone is tighter.

Notes: The J Mascis Ram's Head Big Muff Pi fuzz pedal pays homage to the sonic centre of the alt-rock legend's iconic tone of equal parts thickness and clarity in a special edition white and violet finish.

"That's my sound. The Muff is always on," J says. "All distorted sounds begin with the Muff. That's what I grew up playing so it's kind of amazing to have my own signature one."

Based on the highly coveted 1973 Electro-Harmonix V2 Violet Ram's Head Big Muff, J's signature Big Muff produces the indulgent fuzz and exceptional sustain used as his sonic centre for decades.

The fuzz is sonically more articulate than other Big Muffs with excellent string separation and dynamics, which make it one of the most versatile Big Muffs. The pedal's response feels smooth and aggressive making your leads scream and chords thunder.

Feel the fuzz of a guitar giant: the J Mascis Ram's Head Big Muff Pi fuzz pedal from Electro-Harmonix.

Notes: The Nano Pulsar takes tremolo beyond the ordinary and mundane. Equipped with a collection of tremolo-modulating waveforms and the option of operating in Triangle or Square Wave modes, the Nano Pulsar is a tremolo/panner treasure chest. In mono, it's simply amazing, or, connect it in stereo to create shifting waves of sound that surround you and fill your space with weaving, pulsating energy.

For all its power, the Nano Pulsar's layout is intuitive and using it is easy. There's often a perceived volume drop with tremolo when the effect is engaged so we've included a Volume control. It allows a player to fine-tune their output level when the effect is on, and is a very useful addition.

The Nano Pulsar's Depth knob adjusts the amount of tremolo applied to the signal. Past maximum (around 1 o'clock) the modulation becomes asymmetric and warps the audio signal between positive and negative phase. This creates a unique style of tremolo which sounds great alone or can be used in combination with other effects like the Oceans 11's Shimmer patch to produce compelling synth-like sounds and textures.

The Rate knob provides a full range of speed adjustments for the tremolo or pan effect, and when you start to max out the Rate and Depth controls you enter ring modulation territory for a surreal sonic joyride!

Unlock a world of advanced sound shaping and control. Create tremolo and panning effects that go from sublimely beautiful to downright shocking. The compact Nano Pulsar will be your do-it-all, go to pedal for all things tremolo and panning.

Notes: Originally designed by Josh Scott of JHS Pedals and graphic designer, Daniel Danger as a homage to Electro-Harmonix in what Josh and Daniel consider the company's design heyday of the 1970s, the EHX Lizard Queen Octave Fuzz is a nano-sized version of the pedal brought to life by the engineers at Electro-Harmonix that has all of the tones and vibes of the original circuit design by Josh. The tone is inspired by EHX's fuzz pedigree with a unique analog octave up circuit that has all the vibe of the original design first featured on the JHS Show in 2022. This creates a completely new and unique EHX fuzz sound we've never heard before. To further tell the tale, the pedal is adorned with vintage EHX-inspired graphics designed by Daniel.

Housed in EHX's Nano-sized chassis, the EHX Lizard Queen is a fixed gain fuzz pedal which features Volume, Octave, and Balance knobs. Volume controls the overall output volume level. The Octave control adjusts the level of the octave-up signal from zero to full octave chaos. Perfect for dialing in a crushing rhythm sound or a chimey, clanging lead sound. The Balance knob sets the tone balance between the smoother Shadow setting and the raspy, biting Sun setting. The effect of the Balance control is especially apparent with the octave set high.

Notes: Classic fuzz reimagined and redefined!

Expanding on Electro Harmonix's first homage to the tone that launched a thousand riffs, the EHX Satisfaction Plus delivers a wide palette of tones from classic '60s snarl to creamy lead tone to thick, earth-shaking sludge!

Where the original Satisfaction Fuzz circuit was a focused tribute, the Satisfaction Plus Fuzz treats the classic tone to a modern control set that includes a FAT/NORM mode switch, Bias control, and Tone knob. The added FAT mode features a tone that is bigger and warmer than the NORM mode for woolly leads and giant wall-of-thunder riffs. The Tone control is an active tilt-shift EQ that inversely controls both the treble and bass of the fuzz for broad tonal shifting. Set the Bias control to dial in the fuzz character from balanced and open to gated and snarly.

Notes: The MOD REX is a kinetic tour-de-force that lets you weave compelling, shifting, musical tapestries. Whether you are a guitarist, synthesist or electronic musician you will find it inspires your creativity and stretches your musical boundaries.

Four independent modulation sections:

The heart of the pedal is its four, independent modulation sections synced in time, they are:

MOD features great sounding EHX Vibrato, Flanger, Chorus or Phaser. The Depth knob lets you set the amount of the effect while Feedback controls the resonance of the Flanger and Phaser.

TREM delivers tremolo, an effect that modulates the volume of your signal. The Depth control sets tremolo intensity.

PAN modulates between left and right in stereo operation. In mono operation the PAN section acts as another tremolo section, but with the wave shapes all inverted!

FILTER offers a choice of a modulated LPF, HPF or BPF. In LPF (low pass filter) frequencies above a modulated cut-off point are cut. In HPF (high pass filter) frequencies below a modulated cut-off point are cut, and in BPF (band pass filter) frequencies above and below a modulated centre point are cut.

Each section also features a choice of four LFO shape options: rising sawtooth, triangle, falling sawtooth or square wave. They affect the way the modulation transitions and provide advanced creative control over the specific section as well as the way they interact with each other.

Tempo control that's flexible and powerful:

The MOD REX delivers virtually limitless polyrhythmic possibilities.

Its TEMPO component gives you nine note-length choices for each of the four modulation sections. They are independently selectable in increments starting at a whole note and ranging thru subdivisions that go up to a 16th note. In addition, any of the sections can be bypassed.

The MOD REX's tempo (displayed as beats per minute or BPM) is adjustable with the Tempo knob, Tap Tempo footswitch or by using an expression pedal into its EXP input. It can also be synced to an external device with MIDI Clock or an external pulse clock.

MIDI and the MOD REX:

The pedal's robust MIDI implementation enables you to sync devices quickly and easily as well as automate functions and changes so they occur precisely when and where you want them whether you are working at home, in a studio or live.

The MOD REX accepts MIDI to enable it to tempo sync the modulation rate with an external device, to recall presets via MIDI Program Change messages and to control any parameter on the MOD REX via Control Change messages.

Extras:

The MOD REX lets you save and recall up to 100 presets. It comes from the factory with 20 great programs.

The pedal features full stereo input and output.

An external foot controller input makes banking up and down thru presets quick and easy.
