More Bad Muff

From the vendor

Boutique Big Muff-based box of bad-ass.

Using NOS BC184C transistors apparently gives this extra mojo, so we've sourced exactly those for you.

This circuit covers a lot of tonal ground. It cleans up really well with the sustain and heat dialled back, giving light crunch through to Muffy fuzz. Wind up the heat control to bias Q1 to within an inch of its life and you have full-on fuzz fun with your Muff tone stack shaping the results.

The back end is a FET boost rather than the typical gain recovery stage, giving you 'nuff output.

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 and vertical-mount pots. Please choose appropriate knobs.
