Electro-Harmonix

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: With its take on the cult-classic, chainsaw distortion pedal, the EHX Hell Melter takes distortion to its extremes. The Hell Melter features expanded controls and tonal capabilities, allowing the already in-your-face sound of the pedal to broaden by switching to more open clipping options and boosting the internal voltage for increased headroom, less compression, and more attack.

Originally designed as the ultimate in high-gain tone, this world-famous distortion circuit is known for the death metal sounds of Sweden's Entombed and the shoegaze wash of My Bloody Valentine. It's even found a home in the rig of David Gilmour!

The EHX Hell Melter's expanded control set includes Gain and Level controls, and a powerful active EQ featuring with parametric mids for improved versatility. The Dry level control allows for blending your input signal for improved low-end when used with a bass or even blending in other distorted tones.

Boost Footswitch engages an input gain boost and volume boost which is internally adjustable. The Normal/Burn switch toggles between the classic chainsaw sound and the more open clipping option.

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: 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.

Notes: Expanded Freeze in a lowball-sized package!

Meeting between the original Freeze and Superego pedals is the Pico Deep Freeze Sound Retainer. With the ability to freeze a moment in sound, the Deep Freeze can act as a sustain pedal for holding chords and notes as backing for your playing or as a platform to manipulate your tone into new sounds impossible with a normal guitar. In addition to the original Freeze's abilities, the Deep Freeze features layering, adjustable attack/decay speeds, glissando, dedicated volume controls, and 3 modes: Latch, Moment, and Auto, making it powerful pedal punching well above its weight.

The Deep Freeze allows for instant sound freezing in three modes of operation. Latch freezes sound each time the footswitch is pressed until the effect is bypassed, while Moment mode freezes sound only while the footswitch is held down. Auto mode captured sound automatically each time it senses signal above its threshold for virtually foot-free freezes. These three modes make it easy to operate the Deep Freeze in a way that fits any playing style.

Controls on the Deep Freeze let you further tailor the operation of the effect. Separate DRY and EFFECT volume controls let you blend signals from subtle backing to 100% effect experimentation. GLISS adjusts the morph time between freeze sounds creating otherworldly soundscapes. The SPEED/LAYER knob adjusts either the attack/decay time of the effect in Moment and Auto modes, or the amount of layering possible in Latch mode which makes playing impossible chords possible!

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.
