Does anyone have any experience with Fuzz Central's Axis Face Fuzz? I've never played a an ff style pedal and this one seems pretty legit. I know that ge has all the mojo, but I value the stability of si. Sorry not sorry.

I've worked up a turret layout, but I figured I'd fish for opinions before committing. Values you'd change? Alternatives for the transistors?

Sorry if this build has been discussed before, but the search didn't turn up much.

Sometimes there is a cool silicon ff but i mostly build germanium with the transistors, resistors, caps, battery, style of construction etc.. under careful consideration. Everything affects the sound of a ff. That being said, axis is not bad. Your own ears are your best tool. Keep it if you like it.

I just built one alongside a Harmonic Energizer in one pedal.

I used a P2N2369 for q1 and an AC127 germanium in q2. Sounds great.

I accidentally 'invented' my own 'bias' control one day when I miswired the gain pot. If you wire the 15uf cap to lug 3 of the attack pot instead of lug 2, and send 1 and 2 to ground, then it works as a bias control! No idea if this can be harmful to your semiconductor but so far so good on the 3 Fuzz Faces I've done this on. You might want to try strapping a resistor across the pot to lower the value as the nice starved tones are a bit bunched up.

I used a 20k trimmer for the q2 (regular) bias resistor.

I think the input attenuator pot works better than the original Fuzz Face gain/attack pot.

I'd say build one but use hole board or vero and stick in some sockets for the trannies and the input cap and experiment.

Thanks for the tip on the variable emitter resistor: I'll have to give it a try. It makes sense, but I hadn't thought of it.
