Based upon the fuzz circuit found in the Vox UL730 and 7120 amplifiers used by The Beatles to record the Revolver and Sgt. Pepper's Lonely Hearts Club Band. A high gain, spitty fuzz with adjustable midrange filter. Surprisingly suitable for more aggressive music too. Features include N.O.S. hand selected silicon transistors, true bypass switching, 9v power jack, led indicator, and internal trimpot to adjust the amount of gating in the fuzz. Great for nailing those Beatles fuzz sounds.
