THE CORRUPTOR
Build Document last updated april 2018
for PCB version 3.0
The Corruptor is a brutal sounding and glitchy CMOS-based fuzz
and ring modulator. It turns your guitar signal into a square wave
and modulates it against an internal oscillator. The blend pot goes
from pure fuzz to pure ringmod-sounds or a mix of both.
This circuit works best with high output pickups. It's a gated circuit
by nature of the CMOS logic. If you are using single coils and need
more sustain, try a boost or compressor in front. Happy playing!

- Page 2 • CV input has been added! Now you can modulate the carrier frequency with an external Control Voltage device (such as the Parasit Studio CV Generator or a synthesizer with a CV output). General builds tips •...

- Page 4 Wave Oscillator (LFO) that will modulate the carrier frequency. So try connecting the LFO output from a synthesizer, modular system or the Parasit Studio New Wave CV Generator. CV jack Wiring To hook up the CV (control voltage) input jack, connect the CV pad on the PCB to the tip of a 3.5mm jack (or jack of your choice).
- Page 5 Possible mod – range switch C8 (220nF) sets the oscillator range. The stock value of 220nF will be fine for most uses, but when using the CV input it can be nice to be able to switch the oscillator range for different CV responses. You can change it to a lower value for higher frequencies and a higher value for lower frequencies, or why not use a switch to toggle between 3 different settings? :)
