It’s december already!
From Dylan159’s Unreleased circuits on FSB:
I’m not done with fuzz faces it seems. This one’s goal is to keep all the classic cranked gain tones while making the ill-treated gain knob more useful. This is accomplished by moving the gain control to the first stage. When maxed, you have a classic, low input impedance, high gain fuzz face, because the emitter is effectively grounded. At low gain, the input impedance rises to something close to 200k or more, hopefully giving an interesting sound without the usual dulling that happens. Last but not least, this one doesn’t need trimming! the emitter resistor assures predictable bias even with widely differing beta. You can still make it adjustable if you like to mess with it. Care has been taken to avoid blocking, since we’re adding capacitors. With these values, blocking is roughly the same as with the original.
Update: Oops. There was a cut missing from the fuzz 3 + 100µ cap.. 8.12.2022, now fixed… and verified.
