Affectronix 4uzz. My original concept 15 years ago I built 4 variations from the “Multi-face” article, no footswitch and in a plastic RadioShack enclosure. Decided to improve upon the concept as I get back to building again.

The 4-in-1 classic fuzz box. And first UV print job from Tayda (used Affinity Designer). 4 PedalPCB boards, switch between with a rotary 3P4T. Messed around with a lot of my Ge and Si transistors in pretty much all the circuits the get the best sounds.

1. Fuzz face with Ge (two un-named) vs. Si (BC108B & BC108C) switch
2. Analogman Sunface (BC108C & un-labeled NPN Ge)
3. Big Muff Pi - Rams head
4. Harmonic Percolator - Albini mods with NTE102 Ge and 2N3565 Si

Being my first enclosure printing order and first PedalPCB circuits, I messed up the orientation of the Fuzz/Vol controls on all the circuits and had to wire them up individually. Fortunately other than that it came together nicely.

I switched the location of the Vol and Fuzz controls on the enclosure art so I had to free wire those. And the input hole was blocked by the Big Muff board so I had to turn that 180 degrees. In the end it all worked out though! Lessons for next time.
