The Data Corrupter is one of those pedals that might be quite hard to describe but easy to understand once you hear it. It crushes and mangles your guitar sound in a way that no other single pedal could because it amplifies your signal into a crushing square wave fuzz sound.

Once that signal is brutally destroyed, it’s multiplied and divided (and then modulated) to create an incredibly complex sound. It has the feeling of turning your guitar into some sort of synth pedal with octave up and octave down abilities too. But not in the traditional sense of pitch shift.

Wild!

This pedal is wild and definitely made for the more expressive and experimental guitar players out there. The frequency modulator will produce smooth pitch-shifting bends or glitchy, sci-fi effects if necessary.

Subharmonic

The Subharmonic switch will engage different harmonics and octaves to taste. As with all things EQD the trick is experiment until you find the formula that works for you.

Here’s what EarthQuaker Devices say about the Data Corrupter

A wild, yet repeatable three-voice Modulated Monophonic Phase-Locked Loop (PLL) Harmonizer, the Data Corrupter takes your input signal and brutally amplifies it into a crushing square wave fuzz tone. That signal is then multiplied, divided and modulated to create a harmonically complex, expressive and touch-responsive analog synth tone up to three octaves below (or above) the original signal, plus additional harmonies.

  • Wild Three-Voice Guitar Synthesizer w. Crushing Square Wave Fuzz
  • Frequency Modulator produces smooth portamento pitch-bends (Glide mode) or retro sci-fi laser effects (Vibrato mode)
  • Master Oscillator and Subharmonic dials allow for harmonies up to three octaves above and below your original signal
  • True Bypass
  • Silent relay-based switching
  • All-analog signal path
  • Top-mounted jacks – for effortless pedalboard implementation

The central nervous system at the heart of the Data Corrupter’s hive mind is the Master Oscillator. The Master Oscillator’s “Root” (the octave of which is selectable via a three-position rotary switch) adjusts the frequency range and tracking response of the input signal, which is then synthesized and harmonized by one of eight Master Oscillator programs, adjustable by an eight-way rotary switch. 

From there, the Frequency Modulator applies pitch-bend modulation to the Master Oscillator. In Glide mode, you’ll hear a smooth portamento as each note slides into the next. In Vibrato mode the pitch modulates up and down for a retro sci-fi laser effect.
 
The Subharmonic assimilates the input signal into one of eight lower octave programs between one and three octaves below the original. For a more stable lower octave, set the Subharmonic’s Root switch to the Unison position, which divides the Square Wave input signal, and removes the Frequency Modulator from the Subharmonic signal path.
 
To unleash the cracked machine lurking within the Data Corrupter mainframe, set the Subharmonic Root switch to Oscillator and try not to look away as the sonic malware you just installed mangles your input signal into the sum and difference of both the Master Oscillator and Subharmonic with the Frequency Modulator applied to the upper and lower octaves.

Each and every Data Corrupter is built one-at-a-time by a team of ensigns aboard the Starship Enterprise locked in orbit around the Borg Cube of Akron, Ohio, USA. Make it so. Engage.

Fuzz

A fuzz pedal is one of the earliest and most aggressive forms of distortion, turning your clean guitar signal into a thick, saturated wall of sound. It works by clipping the waveform almost flat, creating a compressed, gritty tone full of harmonic overtones. The result is raw, unruly, and unmistakable — from the sputtering breakup of vintage germanium circuits to the searing sustain of modern silicon designs. Fuzz pedals react strongly to your guitar’s volume and pickup choice, making them dynamic tools for expressive players.

Whether you’re chasing the classic tones of Hendrix and the Smashing Pumpkins or exploring heavy, experimental textures, fuzz remains a favourite for its personality and unpredictability. It can sound smooth and sustaining, or wild and velcro-like, depending on how it’s set up. A good fuzz pedal cuts through the mix while adding thickness and attitude, turning any riff or lead line into something bold and unmistakably alive.

Guitar Pedals

Your pedal is like a signature dish for your sound — a flavour-packed creation that transforms the bland ingredients of your guitar into something unforgettable. Each one adds its own seasoning, texture, and heat, turning a simple meal into a feast of tone.

These tasty little boxes sit in a row, like plates on a buffet, letting you mix and match flavours as you play. With one tap of your foot, you can swap sweet for spicy, subtle for smoky, and serve up something completely new. From the comfort food of warm overdrive to the fiery kick of fuzz, from smooth jazz sauce to heavy-metal spice, pedals give players a full menu of options to express their taste.  And just like with food, once you’ve tried one dish, you’ll want to sample them all.

Collecting, trading, and discovering new flavours soon becomes part of the joy of being a tone-loving gourmet geek with a guitar.

New

This is brand new, fresh in, and a UK warranty is included. New Gear always comes from trusted UK music retailers.

Octave

An octave pedal shifts your guitar signal up or down by one or more octaves, blending the altered pitch with your original sound to create a fuller, more complex tone. It can add a deep, bass-like layer underneath your playing or a shimmering high octave on top for lead lines and solos. Classic analogue octave pedals often produce slightly gritty, organic sounds, while modern digital versions track more precisely and can offer multiple octave ranges.

Octave pedals are great for thickening single-note riffs, creating synth-style textures, or even mimicking bass parts when playing alone. They pair well with fuzz or overdrive pedals for massive, harmonically rich tones. Whether you’re after vintage Hendrix-style octave fuzz or a modern polyphonic sound that tracks chords cleanly, an octave pedal opens up a world of creative possibilities and adds real weight and character to your tone.

Pitch

Pitch pedals alter the frequency of your guitar signal, changing the perceived note or adding harmony. They can shift notes up or down by fixed intervals, create harmonies, or produce dive-bomb and whammy-style effects without a tremolo arm. Pitch shifters and harmonisers are great for thickening solos, simulating multiple guitars, or experimenting with creative, otherworldly sounds that expand your tonal range.

Rotary

Rotary pedals recreate the swirling, moving sound of a rotating speaker cabinet, adding rich modulation and a sense of motion to guitar tones. They typically simulate the changing pitch and volume caused by spinning speakers, producing anything from subtle shimmer to deep, pulsating swirl. Rotary effects are often used for clean and lightly driven sounds to add depth, movement, and a classic, organ-inspired character.

Synth

A synth pedal transforms your guitar signal into rich, layered tones that mimic the sounds of a synthesiser. Using pitch tracking and waveform generation, it can produce everything from deep bass lines to shimmering pads and futuristic leads. Synth pedals open up a wide creative range, blending the expressiveness of guitar playing with electronic textures, making them ideal for experimental sounds, ambient music, or adding a modern edge to classic riffs.

Vibrato

Vibrato refers to a guitar pedal effect that modulates pitch slightly up and down, creating movement and a sense of wobble in the sound. Unlike tremolo, which changes volume, vibrato affects pitch only, producing anything from subtle shimmer to pronounced, warbling textures. It is often used to add character, depth, and vintage-style modulation to guitar tones.
