From the vendor
This fruity little number is a lovely tweaked take on the op-amp Big Muff Pi, and not rotten at all. Usual Fuzz, Tone and Vol controls are joined by a very useful three-way toggle switch. This alters the tone section for full, flat or scooped mids - you could lose hours with the tonal possibilities. We've tweaked it ourselves, as the trace has the fuzz pot as linear taper - no way. It needs to be reverse log to be any use at all, so that's what you'll get as we care. The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs. 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 will not take a battery. Knobs are not included. Builds are only available with full kits including enclosures. Please choose appropriate knobs.
