Easy Face with input cap blendVerified
Based on the Easy Face with input cap blend
From the post
Joe Gagan's Easy Face hybrid Fuzz Face with input cap blend control - as requested. You should get away with almost any PNP germanium as there's 2N3096 driving it. Documentation states that the trimmer should be used to get ~4.5V on Q2 collector - I suggest you tune it by ear :) This one uses positive ground, so check your wiring or use a voltage inverter like this.
