Z.Vex Fuzz Factory - Vexter
This is a five-knob fuzz using two new old-stock sixties germanium transistors. The circuit is not modeled after any classic fuzz design, but should have been around when Leary was still lucid.
Although the five knobs are named for the parameters over which they seem to have the most control, please don't hold me to it. They are controls for various operating levels and biases, and basically shape you a personalized fuzz.
