From the vendor

The daddy of thick, meaty fuzz. Everyone needs some Fluff in their life, but not everyone is a fan of the scooped tone control. Yes, we offer kits with AMZ presence control tone sections with mid-shift, but here's another flavour - a Baxandall tone stack. OK, yes - we know. It's actually a James tone stack since it's passive, but no-one is going to search for that. Live with it. There are no hard and fast rules about values in this tone set up. One person will love something the next hates, so after some experimentation we've decided on the values from the discontinued Catalinbread Manx Loaghtan with a slight tweak. Feel free to substitute your own values to suit. Kits available for the following versions of this classic: • 70's (3rd) version • Green Russian • Black Russian • Civil War Russian • Tall Font Green Russian • Ram's Head • Triangle • Violet Ram's Head • V3 79#2 (Mascis) • Creamy Dreamer • Stoned cleric • Elk Sustainer (NPN Version) Mascis model doesn't have the tone bypass that was on the original, but why you wanna bypass the tone? Creamy Dreamer doesn't include the ludicrous power filtering of the original. What's the difference in the above versions? That's a website all to itself, and whaddayaknow? There IS a fantastic resource on all things Big Muff. Check out Kit Rae's Big Muff Pie page. 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: Lots of Big Muff Pi variants Difficulty: Medium PCB size: 50 x 46mm Knobs required: 4 Enclosure: 1590B Download the INSTRUCTION PDF
