Right. I think they actually are very important to the sound (there really isn't much else in the box). The sound of this pedal is pretty unique, it's the pedal Colin Greenwood of Radiohead uses on his bass in the songs "Exit Music (for a film)" and "Myxomatasis". It's super thick, sticky, grungy fuzz. It sounds like 60/70s biker film fuzz.
Lovekraft, I was wondering how you got the part number 2SC536F for the transistor, it seems like a couple places fairly nearby may have it. I do see that is says C536 F7G on the transistor itself, maybe you derived it from that?
Thanks for all the help so far guys, I truely appreciate it.
