For Fuzz Friday here's another cool design from Brian at Smallsound/Bigsound. It's a unique silicon/germanium hybrid fuzz box with all kinds of options. This was traced over on Freestompboxes and Brian was kind enough to chime in and shed a little light on the circuit. There have been a couple versions of this circuit with both PNP germaniums with a charge pump and this version with NPN germaniums. The dip switch is there to give the option of bypassing the input buffer. For the buffer to be on, switch 1 down and 2 and 3 up. To bypass the buffer, switch 1 up and 2 and 3 down. There are a couple question marks around the circuit still, specifically 2 diodes (which are probably schottkys) and one larger capacitor (probably 330nF), so socket things and experiment. It seems to be a very tweakable circuit, and it work well on guitar and bass.
