FuzzPup Big Muff Pi

From the vendor

This is part of our FuzzPup range of circuits designed for 1590A builds. Please read the general build doc available here and ensure you're happy with what's involved. They're not especially difficult, but working in a confined space can be fiddly. Take heed. This kit is especially tight so you must be absolutely 100% happy with tight work to take it on.

Of course there's nothing stopping you using these PCBs for 'standard' builds. They're Direct Connect compatible.

A different PCB is available for 'standard' 1590B builds - see the related products listed below.

The daddy of thick, meaty fuzz. Everyone needs some Fluff in their life. Now you can have it in a teeny 1590A package.

Kits available for the following versions of this classic, with more to be added soon:

• 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)

Mascis model doesn't have the tone bypass that was on the original, but a Muff without Muff tone is no Muff at all. Creamy Dreamer doesn't include the ludicrous power filtering of the original.

NOTE: Kits are supplied with 0.125W resistors, which are tiny. Any of the kits that require 1uf capacitors will be supplied with multi-layer ceramic as film caps are too deep.

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-Fluff. Kit Rae's Page is a great resource.

All this fuzzy fun in a 1590A enclosure.

Comes with a separate daughterboard to easily mount the pots to the main PCB.

Pots have round shafts so you'll need set-screw fitting knobs. Pot spacing is 18mm.

Note: Images showing completed PCBs with pots attached and in-situ in the enclosure are general FuzzPup pics so you can see how they fit together.

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.

Inspired by: Lots of Big Muff Pi variants

Difficulty: Hard/Very Fiddly

PCB size: 30 x 50mm

Knobs required: 3
