Zonk Machine

I've probably put more hours into testing the Zonk Machine than any other circuit! It seems to have its own rules with assoociated voodoo that I simply will not go into. Anyway, here's a version I did to sell (to make up for the hours of research and development I've put into getting this circuit sounding remotely good), 9 months since I started working on it, but it sounded so cool at our last Windscale rehearsal that I think I'm going to be keeping it.

Russian Booster

A booster based around the Russian GT308 germanium transistor, more info here. Supposed to be for Bass guitar but sounds good on guitar also. Cuts bass frequencies, and boosts some high frequencies. Some frequency info from the linked thread above - 10 Hz: +2dB, 63 Hz: 0 dB, 100 Hz: -1,6 dB, 200 Hz: -8,5 dB, 350 Hz: -25 dB (notch), 500 Hz: -14 dB, 1000 Hz: -6 dB, 1500 Hz: -3,5 dB, 3000 Hz: -1,5 dB.

Fuzz Face

Fuzz Face for Adrian in the USA. Larger capacitors for more bass, and a bias control for tonal variety.
