Next Parasit project, this one is a pretty special kind of noise maker.
Subspace Transmission Fuzz.
Of course, there is a fuzz in there, a pretty cool "comparator based fuzz" as they put it. The star of the circuit is a ISD1820 lo-fi record/playback chip that lets you record up to 20 seconds. The playback can be pitched up and down - and it can be repeated (toggle switch) but it's not a real looper, as the chip resets after each play. Nonetheless this "reset procedure" can be accounted for when producing a clip so that it becomes a rhythmic element - or sort of.
You can also stretch/condense a recorded phrase with the Pitch knob to the "right length". Or, you can record something without input and that produces some white noise type of sound that - pitched down - becomes some evil rumbling drone.
The BLEND knob pans between the Fuzz and the playback. TONE is after that and is applied to the mix of fuzz and playback.
Fun stuff, indeed!
I used momentary foot switches for PLAY and RECORD, because this was meant to be a pedal, not a table top device. Sure, it's great on a table top, but also on the floor. Putting the PITCH on a expression pedal could be fun too.
And again, I changed the layout a bit, all knobs are wired, because top jacks.
