Earthquaker Devices Data Corrupter Modulated Monophonic Harmonizing PLL

Ditch the calculator and prepare for sonic chaos with the Data Corrupter, a monophonic analog harmonising PLL that transforms your input signal into a crushing square wave fuzz tone. This wild three-voice guitar synthesiser brutally amplifies your sound before multiplying, dividing and modulating it to create repeatable yet unpredictable results. The Master Oscillator serves as the central nervous system of this cyberpunk machine, featuring a three-position Root switch that feeds your input in its original octave (Unison), one octave down (-1) or two octaves down (-2) for optimal tracking compatibility with your instrument.

The Frequency Modulator adds pitch-bend modulation to the Master Oscillator with two distinct modes: Glide mode produces smooth portamento as notes slide into each other, while Vibrato mode creates that classic retro sci-fi laser effect with up-and-down pitch modulation. Meanwhile, the Subharmonic section assimilates your input signal into eight lower octave programs, ranging from one to three octaves below the original. Set the Subharmonic Root switch to Unison for stable lower octaves, or switch to Oscillator mode to unleash the cracked machine within — this creates sum and difference combinations of both oscillators with frequency modulation applied to upper and lower octaves.

The Square control on the Voice Mixer blends in a fuzzed-out square-wave version of your input in its original octave, while the Voice Mixer’s Oscillator and Subharmonic controls adjust the blend of each voice. Every Data Corrupter is hand-built one at a time in Akron, Ohio, ensuring each unit maintains the quality and character that makes this synthesiser a unique addition to any setup.
