Vintage-Sound Overdrive Circuit with Distortion and Fuzz

RS-Timbre "VintODist Fuzz". Vintage-sound Overdrive circuit with Distortion and Fuzz. Controls Include: Input Gain, Bass, Center, Treble, Direct Level, Distortion Drive, Fuzz Enable switch, Fuzz symmetry switches, Fuzz Depth, Distortion Gain, Distortion Level, and Volume. Frequency range is from 10 Hz to 30 kHz with all controls at 50%. Suitable for 6/7/8-string guitar or 4/5/6-string bass. Example gains per frequency with all controls at 50% are; +28.9 dBV @ 40 Hz, +31.9 dBV @ 100 Hz, +31.3 dBV @ 400 Hz, +26.8 dBV @ 1 kHz, +15.8 dBV @ 4 kHz, +7.9 dBV @ 10 kHz, and 0 dBV @ 25 kHz. Caution! Very high gain circuit. The tone controls affect only the Direct signal, and the Fuzz affects only the Distortion signal, while these two signal-paths are mixed in the Output Stage. The Fuzz can be enabled or disabled and comes from Schottky diodes in a shunt-type array, while the Distortion is constant, but mixable, and is from an overdriven LM380 low wattage audio power-amplifier IC. The circuit can be used for a stomp-box or rackmount project. The battery can be replaced by a regulated single-polarity DC supply providing +9VDC or +12VDC or +15VDC at >= 80 mA of current. And though simulator verified, treat the circuit as experimental. Breadboard test before committing to a soldered build.
