From the vendor
Yet another box of gnarly 70's face-ripping fuzz. This lovely little beast's distortion control determines how much un-fuzzed signal gets through, which gives a huge range of tone, from thick-ass growl to cat-bothering fuzz. Each transistor gets its own biasing trim-pot for super-acurate setup. Board-mounted pots for minimal wiring and easy enclosure mounting. If you want the PCB without parts there's a link for that at the bottom of the page. Partial kit: PCB, all board-mounted components, pots. Full kit: As above, plus footswitch and appropriate daughterboard/components for your selected bypass type (see Downloads section for details of those), jack sockets, DC socket, battery snap, hook-up wire, LED. Enclosure (pre-drilled) is available as an option with full kits, and can take a battery if desired with footswitch positioned 22mm higher, closer to the controls. Knobs are not included. Inspired by: Square Wave Fuzz Difficulty: Medium PCB size: 50 x 22mm Knobs required: 2 Enclosure: 1590B Direct Connect compatible (4 way) Download INSTRUCTION PDF
