Earthquaker Devices - Data Corrupter

Fuzz & synth-like tones!The Earthquaker Devices Data Corrupter is a monophonic analogue harmonizing PLL with modulation. It takes your input signal and drastically amplifies it into a crushing square wave fuzz tone that is then multiplied, divided and modulated to create an exotic, yet repeatable, three-voice guitar synthesizer.
The Master Oscillator is at the core of the Data Corrupter’s cyberpunk hive mind, feeding your input to the signal harvester in its original octave (Unison), one octave down (-1) or two octaves down (-2) for maximum compatibility with your preferred instrument and frequency register.
When you’ve chosen your input octave, then the Data Corrupter will perform its calculations and generate an analogue synthesized frequency, which can be pitch-bent for portamento or vibrato sounds by the Frequency Modulator! You can then blend in one of eight Subharmonic intervals up to three octaves below the input and mix in a square wave fuzz tone for ultimate data corruption.
at a glance
• 3-voice synth/fuzz effects pedal for guitar and keyboard
• Subharmonic generator can play one, two, or three octaves below original note
• Master Oscillator voice can play one, two, or three octaves above original note
• Add harmony effects with major thirds, fifths, minor sevenths, and more
• Vibrato setting adds frequency modulation for extra character
• Glide mode for synth-like portamento sounds

Nerd TalkThe core of this pedal is based around a CMOS Phase Locked Loop (PLL) IC. Put simply, the PLL takes your input signal and compares its phase and frequency against an oscillator, generates an output proportional to their difference then feeds it back to the oscillator.
This then causes the oscillator to lock onto the input signal and generate a synthesized frequency. This synthesized frequency is known as the Master Oscillator on the Data Corrupter.
Expressive & Accurate

immersive soundsThis device is inspired by the Electrax Synthax and the “Basic Frequency Synthesizer” by Ray Marston. Neither of these were really intended to be guitar effect pedals and a lot of work went into creating the Data Corrupter to provide incredible tracking and long sustain.
It's likely you will find it more expressive and accurate than practically any other PLL based effect pedal around.
