Thanks Wilkie1, that was exactly the problem. I missed the “T” on the board.
So I have a functional Fuzz now, but it’s not quite right. The attack doesn’t seem to do anything. It makes a very slight change in the sound, but it’s really subtle. The level seems really hot too (I’m 99% sure I didn’t get them reversed, I checked them with the multimeter before I mounted them). At about 1:00 on the level knob the pedal is roughly as loud as when playing in bypass.
Also, I get a lot of noise from the unplayed open strings. For example, fret the 6th string, play a note, release it, and there is a lot of buzzing (fuzzing?) from the other strings that weren’t played or fretted. If I dampen them it immediately stope. There isn’t any noise when the pedal is on.
The bias on Q3 is too hot too, with the trimmer all the way clockwise I still have -7.8 volts.
