Radio(active) Fuzz

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.

  1. 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?

Germanium transistors are becoming more and more scarce and the ones that you do find aren't great options for the classic fuzz circuits...
