Richter Original "Deluxe DistorFuzz" Circuit for Guitar

Richter Original "Deluxe DistorFuzz I" circuit for electric guitar or bass. Controls Include: Input Level, Bass, mid-Center, Treble, Drive, Intensity, Fuzz enable switch, Fuzz symmetry switches, Fuzz Depth, Gain, and master Volume. Uses discrete JFET input stage, slightly modified passive Baxandall tone controls, discrete BJT driver stage, and FET-input op-amps for Fuzz and Output Stages. High-gain circuit. Each stage can overdrive the next, depending on control settings, for a combination of discrete transistor and op-amp distortion. Fuzz is obtained from a shunt-type Schottky-diode array in which symmetry switches set the harmonic content of the fuzz sound. Frequency Range 12.6 Hz to 22.4 kHz with all controls at 50%, extending well beyond standard audio limits with controls at 100%. Suitable for 6/7/8-string guitar or 4/5/6-string bass. Maximum Gain = + 23.6 dBV @ 500 Hz with all controls at 50%, or + 53 dBV @ 1 kHz with all controls at 100%. Shown with a 12V battery. Circuit requires +12VDC @ >= 40 mA. Do not use any other supply voltage. Battery can be replaced by a regulated +12VDC power-supply. Rackmount implementation is recommended. And though simulator verified, treat the circuit as experimental. Thoroughly breadboard test before committing to a soldered build. House in a grounded metal enclosure.
