Would anyone who owns a Hoof Fuzz be so kind as to take two quick measurements? I just want to know how Q2 and Q3 are biased. I would love to know the voltage reading on the collector leg of Q2 and Q3.
Please and thank you.
Please and thank you.

Okay, hmmm, maybe my Germanium transistors are too low gain? 148 and 178 is what I'm working with. I made the 390 ohm biasing resistors into 500 ohm trimpots but I'm only able to get 3.5v or so on the collector of each. That's the max I can achieve but it sounds pretty good...

Ahhh yes - good call. That would have made way more sense since they're 12K and the emitter resistors are just 390 ohms... DUH! haha I'm a jackass sometimes. Thanks!

When I adjusted the bias up from 3.5v to 4.5v on Q2 and Q3?
It seemed to sound better. It seemed to sound more full/hot/fuzzy. It was still doing its thang at 3.5v and sounded like a muff that was running too low on battery maybe? But didn't sound awful. Just wasn't "wow-ing" me. Something seemed dull/off.
I still haven't fixed the tone knob issue though. But I haven't tried to either so that may be why. Heh. I had my folks in town this weekend and we went out of state to visit family. I'll get on top of it this weekend and see if it ain't just a cold joint somewhere.
