The Corruptor is a very brutal sounding CMOS-based ring modulator pedal. It turns your guitarsignal into a squarewave and modulates it against an internal oscillator. The idea behind this circuit comes from the Korg MS20 synth that uses a CD4011 to produce pseudo ringmod effects.

This circuit works best with high output pickups. It is 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. To improve tracking of the octave down, use your neck pickup with the tone rolled off.

This kit is a creation by in cooperation with If you have any problem with the content of the kits like mising or wrong parts, please contact Musikding (Klaus) at For any technical problem relating to building this project, please contact Fredrik at

5 from 5 Great kit, no problems, insane sound.

First time building a kit, but no problems whatsoever. The DC jack is quite large, so make sure to drill the hole with some distance to the main PCB. The sound is completely insane, which is exactly what is was going for. Great kit, great customer service. Thank you!

5 from 5 Awesome sound

First time building a Parasit Studio kit. And it was a blast. This is version three. Easy to solder parts and a clear documentation are a recipe for a fun build. Always wanted to have a ring mod and this has a nasty fuzz also! Great for my tastes. Would recommend to anyone.
