Big Fluffy Pie - Bass Blender

From the vendor

Our contribution to the happiness of bass players everywhere... a Big Fluff circuit with an on-board clean blend, optional mids control and optional first-stage diode lift switch.

The same circuit variations as our standard Big Fluffy Pie kit are available as a starting point. The clean blend is FET-based, the same our our Blender kit.

You have four options for the Tone section:

• standard with no mids control

• standard (3n9 cap) with mids pot

• AMZ Presence mods V1

• AMZ Presence mods V2

For more details on the two AMZ versions have a read of this.

Lifting the first set of diodes gives a much more open, less compressed sound. Particularly useful for bass.

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. Creamy Dreamer doesn't include the ludicrous power filtering of the original. If you select Hoof/Cloven Hoof then please select Mids - None option as we'll supply those with their individual parts.

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-Muff. Kit Rae's Big Muff Page is a great read.

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.

Pot spacing is tight, so you'll need small knobs - 17mm or less diameter - if you're including the mids pot.

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.
