Yellowcake Il Brutto



Yellowcake (about the v1)

A germanium fuzz, consisting of two socketed NTE 103 germanium transistors.

The bleed control knob limits the amount of input signal. The choke trim knob which also doubles as the yellow LED indicator, controls the amount of break-up from the pedal.

The level controls the overall output volume and the fuzz control adjusts, well, fuzz.

All Aluminum enclosures are etched by me, and its rare that they come looking the same. Some may look a little "cleaner" and some a little "rougher". The sound however will be consistent. The etching process is a bit of labor from start to finish, but I feel it to be neccessary that these are to be made this way... All the while keeping this pedal affordable.
