edit 2016-04-26: Limited edition fully assembled pedals now avaliable!
Here's a new DIY project - the Xor'cist stutter fuzz and ringmod. It's now avaliable as a PCB and as a fully assembled pedal.
I have been wanting to do a CMOS based squarewave stutter fuzz (a choppy on/off type tremolo) for quite a while. I have also been thinking about doing an extended version of the Corruptor ringmod (without the over-the-top sequencer of the King Corruptor) so I decided to combine both these ideas into one circuit and this is the result. :)
It can do fuzz, ring modulation or a blend of both. With the stutter engaged it will do stuttering fuzz, stuttering ringmod or alternating between fuzz and ringmod (depending on the mix knob setting). The momentary stutter footswitch can be disengaged and the LFO can be off/on/gated.
The Xor'cist uses a CD4070 XOR chip (hence the name) to achieve both the ringmod and the stuttering effect. It's basically the bastard big brother of the Corruptor.
