Got one of these for giggles since I'm not much of a fuzz guy. I'm not really impressed. I know the octave sound isn't easy to get but it's really hard with this unit. Hopefully it's not defective. I'll try to get the tranny numbers before I put it back together.

Notice that the diodes are zener diodes

I really have a very hard time believing these diodes are what your schematic states: Twenty volt zeners....
Sorry. Plain out of planes.
