Fuzzhead Fx Red Sun Fuzz
This one started as an attempt to improve an obscure old japanese germanium fuzz circuit from the late 60s called Sekova FA II Fuzz which suffered from quite low output and lack of sustain. After some experimenting I removed the clipping diodes, tweaked the bias and added another gain stage upfront which is borrowed from Roland Bee Baa but with a germanium transistor. For transistor selection I found that these with low leakage and a hfe around 100 sounds good but it is worth experimenting with others especially for Q2 and Q3.
