From the vendor

Yet another notch on the Big Muff Pi bedpost. We were asked to take a look at whether this one was doable on our existing Baxandall Big Muff PCBs, but alas the tone section is different. It's such a nice version it was worth doing a board to make it possible, so here we are. Based around a Triangle era circuit, but with that every so useful Bass ad Mids control. OK, yes - we know. It's actually a James tone stack since it's passive. Everyone calls it Baxandall. Live with it. It's a doozy. Lots of range in those two tone pots - screaming leads to doomy sludge. 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 only available 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. Inspired by: Fallout Cloud Difficulty: Medium PCB size: 50 x 50mm Knobs required: 4 Enclosure: 1590B Download the INSTRUCTION PDF
