Electro-Harmonix

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

Notes: The EHX Flatiron Fuzz is a classic op-amp powered fuzz/distortion. With its late '70s style circuit and symmetrical hard clipping, it's EHX's take on the RAT2 pedal.

The Flatiron Fuzz is extremely versatile. At lower drive settings it remains fairly clean and adds a pleasing mild distortion. As the drive is turned up it transports you to a world of arena rock and produces spectacular, thick, meaty tones.

The stellar sound of the Flatiron Fuzz is a result of its classic, late '70s style circuitry and the fact that it delivers symmetrical hard clipping. As a point of reference, you might refer to the old Rat pedal, but you'll prefer the Flatiron.

The Flatiron Fuzz features three controls: Volume, Drive and Filter. Volume sets the output level while Drive adjusts the amount of sustain and distortion. The unique Filter control is actually a low pass filter with a movable cut-off frequency. This is especially cool because it lets you dial in just the right amount of high-end... from dark to raunchy.

Electro-Harmonix trivia: The Flatiron Fuzz is named after the historic Flatiron Building in New York City. It's an iconic landmark located just down the block from EHX headquarters in the 1970s and it's the building pictured on the pedal.

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: 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: 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: 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: Get that late 1960's fuzzed out, octave up sound!

The EHX Octavix Octave Fuzz delivers the definitive late 1960's fuzzed out, octave up sound together with modern enhancements that update the classic concept. Housed in EHX's rugged nano package, the Octavix features Volume, Boost and Octave knobs. Volume regulates the output level of the pedal. Boost controls the amount of fuzztone and Octave adjusts the volume of the octave above. A mini-toggle lets the player select between 9 or 24 volt power rails and determines the power supply voltage for the entire circuit. At 9V the pedals behaves like the classic, saggy fuzz box. At 24V the Octavix delivers a tighter sound and a richer octave tone. True bypass ensures maximum signal path integrity.

A period-evocative, psychedelic design and blue LED contribute to the pedal's vintage vibe.

Notes: Bridging the worlds of overdrive, distortion, and fuzz in a sub-compact pico chassis!

The EHX Pico Triboro Bridge is a tri-mode drive box with a wide range of tonal possibilities. Featuring Overdrive, Distortion, and Fuzz modes, it bridges any gap in your gain. With a powerful EQ, input contouring, and a pico-sized footprint, the Triboro Bridge can be your tonal keystone or a welcome change from the routine drive.

Starting with Overdrive mode, the gain spectrum ranges from low to mid with an open voicing that can be used as a light always on drive or a solo boost. Engage the Triboro's Distortion mode for additional gain-staging for a tone from crunchy rhythms to fully saturated leads. Transform the pedal into something completely different with the Fuzz mode's over-the-top gain, Gate and Low Pass Filter.

The Triboro Bridge controls features Volume and Gain knobs to control the overall output and saturation of the tone. In Overdrive and Distortion modes, the Treble and Bass knobs act as a Baxandall EQ for simple yet effective tone shaping. In Fuzz mode the Treble knob is now the gate more, controlling the Fuzz's noise gate threshold, and the Bass knob controls a Low Pass Filter for extreme tonal variations. Additionally, the Triboro Bridge features an Input Contouring EQ which can be applied to your tone at the input, for a more modern, sculpted tone in all modes.

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: 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.
