The Black Keys Peach Fuzz

Released in 2026, the circuit uses NOS Fairchild 2N3565 transistors, germanium 1N34A diodes, carbon resistors, and film capacitors. Volume, Sustain, and Mellow-Brite Fuzz set the gain path; a dedicated Octave Sustain footswitch adds octave-up, with a toggle for momentary hold versus latching.

True bypass with mono 6.35 mm input and output. The enclosure measures 84 mm wide x 140 mm deep x 58 mm tall (3.3 x 5.5 x 2.3 in) and weighs 0.36 kg (0.8 lb).
