Big Muff Pi - 3-Band Tone

The daddy of thick, meaty fuzz. Everyone needs some Muff in their life. But sometimes it's nice to try something new...

All the fuzzy fun of your favourite BMP variant but with a three-band tone stack in place of your usual single knobbed scooped mids affair. It opens up a whole new world of sonic possibilities.

We're also offering a clipping switch that swaps out both sets of diodes for yet more tonal variation. Go for this option and we'll include red LEDs and BAT46, the latter doing a very nice job of replicating germanium characteristics without the price premium.

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
• Hoof
• Cloven Hoof
• Elk Sustainer (NPN Version)

Mascis model doesn't have the tone bypass that was on the original, but the whole point of this is that stack. 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.

All this fuzzy fun in a 1590B enclosure. Fat muff in a skinny body. Sweet.

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.
