Space Fuzz!

Just finished this modified Fuzz Face. It's got a toggle to flip between germanium or silicon transistors, bass cut, pre gain and a bias pot on the outside for easy access. Very versatile!

I opted for no fuzz control since the fuzz face circuit only sounds good fully dimed anyway, and the functionality of the original fuzz control is kind of lame to be honest. The "Gain" feature is a way better option in my opinion. It basically works like the volume control on your guitar. When you roll it back it cleans up for some nice overdrive sounds. The "Body" pot is basically a bass cut. By blending between two caps(3.3uf and 10nF) you get very full or thinner sounding fuzz. The bias pot can also give you different shades of fuzz, and is a very usefull tone shaping tool. Especially cool are the sputtering effect that makes you sound like you're playing through a broken radio speaker!

Also added some power filtering and a protection diode to the circuit. There is also a couple of small caps on one of the transistors to reduce some high pitched noise in silicon mode.

Shielded cable, and a blue indicator LED in a fancy clear lens. Pulldown resistor on the switch for popless operation.

The transistors used are AC127 for the germaniums, and 2N2222/2N3904 combo for the silicons.

AC127 Q1=67hfe/0.08mA leakage
AC127 Q2=125hfe/0.15mA leakage

2N2222 Q1=120hfe
2N3904 Q2=150hfe
