pnp fuzz face with contour (like fulltone 69), and bias on the front. the bias is just Q2 bias. I have the correct bias closer to the full ccw so as you turn it cw you get starved Q2. its a 5k1 resistor in series with a 5k pot. my volume pot is 100ka with 100k resistor on the outer lugs. its weird how different fuzz faces work better on different vol knobs. transistors are japanese germanium TCG102 or TCG1024 or something. I really like it but I would have used a 4k resistor in series with a 8k pot if I knew I could have starved it more. and also the bias is slightly out of range with the contour turned all the way up. I think I should have used all 3 lugs for the contour instead of just 2.

Talk about color coordination... black not just on the enclosure & the pcb... but the battery too!  ;)
Nice job

The color coordination is sweet, I dig the big black knobs too.
