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. The almost infinitely variable settings can lead to frightening sqeals, undulating vibratory oscillations, duotone intermodulations, wacky fizzy fuzzes, severely overdriven ultrametal tones with snappy-tight gate action, shortwave whistles, octave up and octave down effects, squinty frying sizzles, ripping velcro fizzles, and pretty soft theremin pitches that can be gently controlled with your volume knob on your guitar. You may never sleep again.
