From the post
I noticed we didn't have this one in the library yet. The circuit is rather interesting mash of different bits and pieces. TS-styled clipping amp with serious sag called "Volts", followed by two fuzz face style (with some features from the bazzfuss) circuits in series, which is followed by Big Muff-styled tone control. Not your standard Overdrive/Distortion/Fuzz, but i do find this interesting.
