Based upon the German Schaller fuzz of the 60's. Updated to a hybrid germanium and silicon circuit. Lower noise floor and more temperature stability. Tons of low end and volume output on tap.
The "texture" knob changes the character of the fuzz from the original chewy compression of the original to a more refined sound, then to a gated sputter.
Features include N.O.S. NPN germanium and modern low noise silicon transistors, true bypass switching, 9V power jack, and led indicator.
Great for all styles of music.
