How to build an effects pedal for fuzz with non-selective frequency tripler.
The Contortionist II kit is an all analog, high octane fuzz box. It produces fuzz with layered octave
overtones similar to those produced by an electronic-bow. The frequency multiplier circuitry creates
harmonics that swell and recede depending on gain setting, pick attack, neck position and pickup. This is a
high gain circuit that can put out up to 2 volts and will provide ample amounts of sustain.
Added features to the original contortionist circuit include a tone control and LED.
