This is a unique and interesting fuzz circuit I found deep in the depths of the aronnelson archival website. The main IC is an AM/FM Radio chip and is used/abused to make a wide range of fuzz tones. Full blown silicon, gated velcro, 8bit, bitcrusher, and just general noise. The original designer left the project unfinished and with a few different modifications, I started with his schematic on breadboard and just experimented from there with values and a few other mods. These chips are still available on ebay and there's also several others in the same family that more than likely have an equivalent pinout. I encourage some more modifications and experimenting.

Can you explain the station switching? Mainly, am I understanding correctly that you really only need, in theory, a 1P4T switch? In other words, only one pole is being used on the switch, yes?
