Hello, I was going to try modding the tone control on my [guinea-pig] J-Bass copy into a fuzz circuit. I know you can do it with certain components like the Stewart-Macdonald Black Ice, but I wanted to do it from the ground up... Anyway, I gather that fuzz results from having a square-edged sound wave. In fuzz pedals, is this acheived with a bistable multivibrator circuit (or whatever else), or is it just a cranked gain control, resulting in tons of clipping? Either way... how would you go about doing it? Any insight = much appreciated.
