Richter Original "SuperZog" Real-Tube Fuzz for Guitar

Richter Original "SuperZog" real-tube fuzz circuit for electric guitar. Controls Include: Input Level, Fuzz enable switch, Fuzz symmetry switches, Fuzz Depth, Drive, Intensity, Bright switch, Bass, Mid, Treble, Stack Sum, and Volume. Uses 3 different tubes; one 12U7 dual triode (not 12AU7), one 12AL8 triode plus tetrode, and one 12DZ6 pentode. Circuitry is based on highly modified versions of the Garnet "Herzog" distortion unit and the Supro Model 1606 guitar amplifier, together with a shunt-type diode-clipping array (using Schottky diodes, for fuzz) and a 3-band Fender-style tone-stack. Not intended to provide much gain but to get fuzz and distortion using real tubes with an expected sound like that of an American-made boutique all-tube guitar amplifier. Experimental circuitry. Untested design. No simulation available. Frequency response and overall gain must be determined during breadboard testing. Power-supply not shown. All tubes work with a single +12VDC supply voltage (originally a car battery) on plates AND heaters. The tubes are available from The Tube Store. https://www.thetubestore.com . Example Supply: 12V DC 1000 mA Regulated Switching Power Adapter, Product ID: 798. $8.95 each. From AdaFruit website. https://www.adafruit.com
