One of the best fuzz circuits ever to be devised, courtesy of Spaceman Effects (who else?). This is a clone board of the Gemini III Dual Fuzz Generator. One half Germanium, one half Silicon, 100% blendable. Yes... you can blend however much germanium to silicon as you wish, making this an almost infinite fuzz tone generator. We call this the "Swiss Army knife" of fuzz circuits. To top things off, the tone control features a reversing switch, which reverses the tone on the germanium side only. Whatever amount of germanium you blend into the silicon side, you can set the germanium to a high tone, for more sing, or low tone for more meat. BRILLIANT!!
