For #fuzzfriday, here’s an interesting take on the Fuzz Face circuit. It uses silicon PNP transistors, but is still a negative ground effect (so daisy chaining power supply is still ok). I guess Sean had a bunch of extra 2N3906s lying around. I took a few liberties with the power filtering and polarity protection, but nothing that will effect the original sound. The yellow/ceramic 100n cap going from 9v to ground is optional, as it’s not all that necessary, but is in the original. It’s setup for board mounted pots if you so desire.
You can find a 1590B drilling template for this effect here.
