2-Voice Diode Fuzz w. 2-Band Tone V2 PUBLIC

2-Voiced Diode Fuzz Circuit with 2-Band Tone, Version 2.

2-voice diode fuzz circuit with 2-band active tone-control, version 2. The Fuzz voices are; standard fuzz from silicon diodes in a feedback array, and germanium-like fuzz from Schottky diodes in a shunt-type array. Controls Include: Input Level, Gain, Drive, Fuzz 1 enable switch, Fuzz 1 symmetry switches, Fuzz 1 Depth, Intensity, Fuzz 2 enable switch, Fuzz 2 symmetry switches, Fuzz 2 Depth, Bass, Treble, and Volume. Note: Symmetry switches set harmonic content of fuzz (symmetry between the two legs of an array emphasizes odd-order harmonics, while asymmetry emphasizes even-order harmonics). Frequency range is from 25 Hz to 25 kHz with all controls at 50%. Suitable for 6/7/8-string guitar or 4/5/6-string bass. Maximum gain = +30.7 dBV @ 1.6 kHz with all controls at 50%, or +80.7 dBV @ 16 kHz with all controls at 100%. Power-supply not shown. Requires a regulated dual-polarity DC supply providing +-9VDC or +-12VDC or +-15VDC at >= 40 mA of current. And while simulator verified, treat the circuit as experimental. Breadboard test it before committing to a soldered build. House in a grounded metal enclosure.
