Earthquaker Devices Now Shipping the Data Corrupter

Earthquaker Devices Data Corrupter PedalEarthquaker Devices has released the Data Corrupter Modulated Monophonic PLL Harmonizer. The pedal features three voices starting with a square wave fuzz that is multiplied, divided, and modulated with a master oscillator.

“The Master Oscillator is the central nervous system at the heart of the Data Corrupter’s cyberpunk hive mind,” Earthquaker writes. “The three-position switch on the Master Oscillator control panel labeled Root feeds your input to the Data Corrupter’s signal harvester in its original octave (Unison), one octave down (-1) or two octaves down (-2). Use the Master Oscillator’s Root switch to fine tune the Data Corrupter’s tracking response for maximum compatibility with your preferred instrument and frequency register. Once you’ve chosen your input octave, the Data Corrupter will perform its calculations and spit out a synthesized frequency, the octave and/or interval of which may be selected via the Master Oscillator’s eight-position rotary switch. The Voice Mixer’s Oscillator control adjusts the Master Oscillator blend.”

A frequency modulator applies pitch-bend modulation to the master oscillator while the Subharmonic section of the pedal creates a sub octave of the Root. It’s then divided over three octaves that are selected by a rotary knob.

Words fail to describe how this pedal sounds, so it’s best to just hear it. Check out the company’s quick demo or go for a deep dive with Juan Alderete from

The Earthquaker Effects Data Corrupter is available now with a street price of $225.
