Big Fluffy Pie Fuzz

Big Fluffy Pie Fuzz

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

The new MultiFluff version of the PCB has optional features above and beyond the standard Fluff circuit:

  • board-mounted toggle switch for alternative diode clipping on the third gain stage.
  • extra pot pads for alternative tone controls with mid-shift.

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

All the above come with the parts to do the tone modification that takes out the scooped mids if that's the kind of thing you'd like to do.

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.

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 versions are available as four-knob with AMZ Presence Control (version 1 or 2) instead of the standard tone circuit. For more info on those have a read of this.

If you want to get really tweaky with your fuzzing you can add the optional clipping diodes and switch. If you go for this option we'll include two each of 1N34A, 1n4001, BAT46 and red LEDs.

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

The PCB is designed for vertical-mount pots to slot straight in. Note: if you select vertical-mount pots these have a round shaft, so take that into consideration when buying knobs - you'll need some that fit with a grub-screw. You can of course wire up 'normal' pots with splined shafts.

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 50mm

Knobs required: 3/4

Enclosure: 1590B

Green Russian Fuzz wonder 5 product stars
"Short review. It's great. Secondly check out the feedback mod on Kitrae page. That is brilliant - but in using a pot to control feedback go for toggle switch and 100k pot - I went with 1M but only kicks in right at bottom of the sweep. Will be changing to 100k. Really love fuzz dog kits. Mark" Mark - 31/03/2018
Green Russian Big Fluff 5 product stars
"Ordered the Green Russian version of this circuit. An excellent song pedal with many useable tones throughout all ranges of the sustain and tone knobs. Although it has the usual mid cut, to my ears it's not as extreme as other pedals of this nature. It's main attraction is the amazing bottom end, but it still never sounds "woofy" or unusable. Cuts through nicely at gig volumes despite its humongous wall of sound! I highly recommend this pedal." Gareth - 11/03/2018

"I went with the Green Russian and it absolutely rocks, I'm already trying to decide on which one to go for next!" kd - 08/06/2017
Tall Font Green Russian 5 product stars
"Awesome! Just finished it, and this thing blows AWAY the Chicago Stompworks Civil War clone I bought last month (for 2x what this kit cost). What front end BOOST this thing has! What tone! You will NOT need a boost after this, it pushes for days! I fucking love this pedal!! Best BM clone I have EVER heard. And... I made it all my little bitty self. Yep. Sho' did." damnedcat777 - 15/04/2017
Big Muff in a Small Box 5 product stars
"The first of many pedalparts builds of mine. Being in love with the Big Muff Pi I was looking to replace my '02 BMP to something with a smaller footprint. While I was at it I was very curious about the Triangle version. Decided to grab the soldering iron a go for it, and what a great decision. The pedal is easy to build, it fits in a standard enclosure and what's most important... sounds absolutely great. Have replaced my original Pi on the pedalboard since then and I couldn't be happier every time I stomp on it." NiLace - 18/02/2017
This is the fuzz you're looking for... 5 product stars
"I'm very particular about bass fuzz sounds - so many that I've tried are too fizzy, or lose too much bottom end and/or definition. But after some careful deliberation, I built the Tall Font Green Russian version of this kit - and it does not disappoint. I can get some almost synth-like fuzz sounds out of it, and cranking it will strip the wallpaper! And most importantly, it'll handle the full range of a 6-string bass admirably without losing anything. If you're not sure which fuzz pedal to go for, buy this one. You will not regret it!"

EQD Hoof 5 product stars
"Bought 2 x NPN Hot Germanium for Big Muff from Small Bear and got 2 2n1306 Transistors with Hfe around 300. Sounds fantastic! A bit of leakage doesn't seem to bother this Circuit and it should take a fairly wide variety of NPN Germanium. If you are thinking of trying the Hoof on this PCB do it, Killer Sounds" JPM - 14/04/2016
Green Russian 5 product stars
"I built the Green Russian and it is a great kit, really nice quality gear. Sounds really cool, much better than I was expecting for the price. I will definitely be buying another kit in the future." Nick C - 29/06/2015
Great Pi 5 product stars
"This was my first build for a FuzzDog kit and I could not be more happy with it. I found the instructions straight forward and easy to follow. I went with the civil war variant and find it to be a very versatile pedal with great tone. I did hit one snag during the build but it was due to a faulty power adapter. So make sure you double check your adapter and polarities. Bottom line, this is a great pedal." Tom - 23/09/2014
A very little Big Muff 4 product stars
"I've built three of these now - A Civil War from the kit and two homebrews on the PedalParts PCB - A violet Ram's Head and a V6. The parts count is high, but it's a straightforward build. Nothing too fiddly and the PCB is well laid out. The finished board will just fit in a Hammond 1590B with room for a battery. Routing the wiring for the knobs is the fiddliest bit, and is easier if you use solid-core wire. The kit is comprehensive and uses high quality components. The resulting pedal sounds fantastic, and having a choice of build specs is really good - they do all sound quite different." John Roberts - 24/06/2013
Excellent muff kit 5 product stars
"This pedal sounds fantastic at a great price. Compared to other ridiculously priced vintage muff clones it's a steal." Big Eck - 19/03/2013
