1978 IC Big Fluff Pie V4-5

Hot! 1978 IC Big Fluff Pie V4-5

The daddy of thick, meaty fuzz. Everyone needs some Fluff in their life.

This circuit is the V4-5 (V5 was a V4 + tone bypass switch - you can make either). A 70's experiment in emulating the Big Fluff Pie tone using op-amps rather than transistors resulted in this babe. It came kinda close, and in the process became its own sought-after sound. Similar territory to what you'd expect from a BMP, but with a heavy, grungy tone.

Check out the characteristic sound of it on Smashing Pumpkins' Siamese Dream.

Pads included to make modifications suggested by AnalogGuru, which make it slightly crunchier, but it sounds great stock. Don't mess!

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

Optional tone-bypass switch is board-mounted for minimal wiring and easy enclosure mounting. The board is designed to take vertical-mount pots (round shafts, so you'll need knobs with set screw fitting), but you can wire in normal ones if you prefer.

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 only available 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.

Difficulty: Medium

PCB size: 50 x 40mm

Knobs required: 3

Enclosure: 1590B

Direct Connect compatible (4-way)

At last, a Big Muff for keeps! 5 product stars
"Had a couple of different versions of BM's previously and never really got on with them. Just didn't have that sound in my head that I was looking for. Well thats no longer the case! This version is awesome!! Sounds really nice and thick with chords without losing any definition (my main complaint about most Muffs)and sustains forever. I fitted the tone bypass switch but didn't bother with any other mods. The standard circuit sounds so good I don't know why you'd want to change it! Did I mention this pedal is awesome....thanks Poodle (again)." Simon - 20/05/2013
