Gee-Wizz Muff

When is a Muff not a Muff? When it's been tweaked into a cranked Marshall kind of sounding vibe.

Fronted by a unity gain buffer, offering up a high impedence input, the Muff-based circuit is given some soft germanium clipping to lighten the mood, bringing it more into overdrive/distortion territory than the all out fuzz you might expect. Of course, if you want to go more traditionally fuzzy you can swap out the diodes for something that'll clip harder, such as 1N4148 which we'll include in the kit, but you'll lose the character the designer was after on the Gee.

Just to mix things up a bit you can now build a different pedal on the same board - let's call it the PeeWizz. Higher gain than the Gee, with tight silicon clipping in place of the softer germaniums on it's gentler sibling.

This circuit is only buffered when engaged - we haven't included the bypass buffer of the original.

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.
