Data Corrupter EarthQuaker Devices Pedal

The Data Corrupter is a monophonic analog harmonizing PLL with modulation. It takes your input signal and brutally amplifies it into a crushing square wave fuzz tone that is then multiplied, divided and modulated to create a wild, yet repeatable, three-voice guitar synthesizer.

The Master Oscillator is the central nervous system at the heart of the Data Corrupter’s cyberpunk hive mind. It feeds 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. Once you’ve chosen your input octave, then the Data Corrupter will perform its calculations and spit out an analog synthesized frequency, which can be pitch-bent for portamento or vibrato sounds by the Frequency Modulator! From there, you can blend in one of eight Subharmonic intervals up to three octaves below the input and mix in a square wave fuzz tone for maximum data corruption.

Data Corrupter EarthQuaker Devices Pedal Controls

• The Master Oscillator is the central nervous system at the heart of the Data Corrupter’s cyberpunk hive mind. The three-position switch on the Master Oscillator control panel labeled Root feeds your input to the 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.
• 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 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.
• If you think you’re brave enough, set the Subharmonic Root Switch to Oscillator and try experimenting with different Master Oscillator and Subharmonic programs to wind up the doomsday clock and inch ever closer to the Singularity. Adjust the Voice Mixer’s Subharmonic Control to set the lower octave volume.
• Finally, (or is it?) the Square control located top-left on the Voice Mixer blends in a fuzzed-out square-wave take of your input in its original octave. That’s it. These aren’t the droids we’re looking for. Move along.

Data Corrupter EarthQuaker Devices Pedal Design Notes

Data Corrupter EarthQuaker Devices Pedal Specs

• Dimensions: 5.65 x 4.75 x 2.25 in. (144 x 121 x 57 mm) with knobs
• Current Draw: 26 mA
• Input Impedance: 1 MΩ
• Output Impedance: <1 kΩ
• Flexi-Switch® Technology: This device features Flexi-Switch® Technology! This relay-based, true bypass switching style allows you to simultaneously use momentary and latching style switching.
• For standard latching operation, tap the footswitch once to activate the effect and then tap again to bypass.
• For momentary operation, hold the footswitch down for as long as you’d like to use the effect. Once you release the switch the effect will be bypassed.
• Since the switching is relay based, it requires power to pass signal.
• Power: This device takes a standard 9 volt DC power supply with a 2.1mm negative center barrel. We always recommend pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not filter dirty power as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES!
