Zonk II (Mojo) Rust

The Zonk II is a raw, aggressive British fuzz circuit that delivers everything from gritty overdrive to sizzling, harmonically rich fuzz with exceptional touch sensitivity. Built around a simple transistor design, it reacts beautifully to your guitar's volume control, cleaning up into articulate, jangly edge-of-breakup tones before exploding into snarling vintage fuzz when pushed. Compared to many heavier fuzz designs, the Zonk II retains remarkable note definition and clarity, making it equally at home with classic rock riffs, garage rock attitude, psychedelic textures, and modern boutique tones. Its dynamic response, cutting midrange presence, and unmistakably vintage character have made it one of the most sought-after and revered fuzz circuits ever produced.

The orange Sprague Pacer adds some extra mojo. Motorola 2n3904 and 2n5088 transistors were matched for this circuit. Carbon composition resistors throughout.
