Fuzz Face with inverter

All-time classic fuzz heard on a zillion classic recordings. The bedrock of many a classic tone.

The PCB with this kit accommodates a voltage inverter, so you can power your posi-ground, PNP builds with a standard negative ground, daisy-chainable supply. If you want to build a version with NPN transistors, or you're happy to have your PNP circuit powered on an isolated supply or battery only, there's our Basic Fuzz Face which will be a simpler build for you.

Versions available with this board are:

  • Newmarket CV7007 (OC77) (PNP Germanium)
  • Combination of Russian and others cans we have in stock (PNP Germanium)
  • JoBo (PNP Germanium - Russian)
  • No cans please - I have some sweet action of my own.

The basic circuit comes in two flavours: Original and Roger Mayer Hendrix Modded. Mayer has slightly higher output level - recommended for germanium versions which tend to max out at below-unity gain.

We've included the option to go for a Reverse Log (C) taper pot for the fuzz control on all versions. It's just better - fact.

The board also includes extra spots so you can make JB or EJ versions, but you'll have to source your own parts for the EJ until the FuzzDog spies come across the right stuff.


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 can take a battery if desired with footswitch positioned 22mm higher, closer to the controls. Knobs are not included.

Perfect 5 product stars
"Bought this kit to build an Eric Johnson spec fuzz, imagining I would have to fudge the extra components in. Not so! The board had the extra places already! 30 minutes later, and I have a monster fuzz on my hands. I substituted the 6k resistor with a 2k7, which gave a better sweep of Q2's biasing. This thing is a beast. Thankyou, Fuzzdog!" Ian - 18 April 2021
Another BC108 5 product stars
"A nice and easy build. I socketed the cans and the smoothing caps so I can interchange if required. I wanted to get a DSOTM vibe and boy, am I not disappointed. I paired it with the POW boost, (Coloursound powerboost clone) and barring my fingers screwing up, I can get "Time" just about tonally perfect. The FF cleans up lovely with a drop in guitar volume and interacts beautifully with my other pedals and amp (Mesa Lonestar Special set to as clean as possible, just before break up). Very impressive delivery as usual." Dave - 07 January 2020
BC108 5 product stars
"I got the BC108 version (same as Hendrix signature), built two in a few days. it just sounds incredibly good! very versatile, especially if you want to play with the bias, good amount of volume too! will probably get another one...there's still some space under the pedalboard after all."

Fuzzzzzzz 5 product stars
"Liked it so much i made another. This one I put a input cap blend pot for versatility and made the bias external. Really love the pedal as a 4 knobber. I can get a lot of usable fuzz and OD with the different settings! Super easy build!" Bill - 13 November 2017
Quality pedal kit and A customer service 5 product stars
"My first pedal kit, always wanted a fuzz face but never wanted the price tag that went with an official one. One of the transistors that came with the kit had a broken wire/leg but fuzzdog was extremely helpful and immediately sent me a new one for free. Soldering main circuit was simple enough but I did find connecting all the components inside the enclosure to be a bit of a hassle but nothing I couldn't do, the free daughterboard that came with it made it a lot simpler. Couldn't be happier with the pedal. Will be buying another kit in the future!" Daniel Cain - 31 January 2017
'A Game of Clones' more addictive than a box set. 5 product stars
"This is my second build, the first being the Tonebender MkII (Marshall Supa Fuzz). I now have 'clones' of two iconic pedals and valuable building experience too. For this pedal I used a pair of BC183L's with the bias set at 5v. I installed ic sockets for the trannies so I can try other ones for comparison. I popped in a smoothing cap on Q1 (marked 47) to help take out most of the fizz and the result is sonic awesomeness in an innocent little casing for which the family and neighbours are extremely grateful. Whether by accident or design the pedal makers in the sixties got the mix just right in these two pedals as did the guys a decade before that with the Strat and the LP. We owe them a lot and we owe Fuzz Dogs huge thanks for keeping things affordable and fun." Steve - 17 April 2016
this is a really well thought out kit,great for peeps who are new to pedal building! ! 5 product stars
"I went for the npn ac176 germanium build with roger m mods kit and it was a lot of fun putting together such a well thought out kit, the pcb is a two sided pro standred board that made soldering so easy,..the downloadable pdf instuctions tell you everything you need to know about the build you chose weather it be a npn or pnp build you chose..I couldnt recommend this enough for frist time pedal builders as you have the fun or putting it together and understanding how the circuit works plues at the end you have a vintage voiced fuzz...high quality parts,matched transistor (my kit had marked transistors for Q1 & Q2)...all I can say is I cant wait to order the shin ei fy - 6 kit :-)" Daniel Allan - 05 April 2015
Awesomely fuzzy pedal 5 product stars
"Went with the germanium neg ground version to go with my recently bought crybaby - fabulously dirty sound, absolutely amazing pedal - thanks again!!!" Penny - 31 March 2014
Everyone should have one of these. 5 product stars
"I went for the 'Hendrix / Mayer' version with 2n404 transistors and it took about half an hour to build, including the biasing which was simple. It sounds great - thick and plenty of bass response. It cleans up well from the guitar's volume control, allowing some nice Hendrixy rhythm sounds, although the pedal itself sounds best with the gain control all the way up. Surprisingly, it handles chords without turning too mushy. One important point though - it doesn't like being behind a buffer as it messes with the input impedance." John Roberts - 08 December 2013
Fuzz face 1st build 5 product stars
"Always wanted a fuzz face pedal? Me too! want to pay 100? NO WAY! Have I built a pedal before or do I have any experience in soldering circuit boards etc? NO! So, if, like me, you want to achieve fuzzy nirvana, then buy one of these kits, go search you tube etc to find out about soldering, buy yourself a decent soldering iron, not a cheap 5 one off the market stalls, take a deep breath and take your time to assemble what is a very good,easy to assemble, solid, well thought out kit at a fantastically decent price. I am now the proud owner of an authentic sounding fuzz face pedal.If you get stuck, use the contact section to send a message and you will get all the info you need. If you get stuck on resister values, there are lots of apps out there for iphone etc, so go look. So many thanks to poodle for such a great web site and range of products. I'll be back!" alan hodges - 26 May 2013
Fuzz Face 5 product stars
"I purchased one of these kits as my first attempt at building my own FX pedal, it arrived swiftly and well packaged. Built it today in a little under 4 hours and it sounds great, needs a little tweaking and a paint job, but other than that it will be used at my next gig in a few days time. Many thanks to Lee for the great service, I've got the bug now so I'll be ordering more kits from Poodle's Pedal Parts in the future" Rik Stewart - 17 February 2013
Fuzz-a-licious 5 product stars
"I play Hendrix, Cream etc. Wanted Germanium. Didn't want to pay stupid. This pedal sounds AWESOME (and yes, CAPS LOCK is cruise control for cool). Easy build, great quality materials. Highly recommended." Rob - 23 January 2013
Unbeatable 5 product stars
"I went for the 2n404 option and modded mine slightly with a surface mount bias pot (which I highly recommend and for more than just glitchiness). I was truly surprised at how good what I'd just built sounded . I've built a Big Muff and a Super Fuzz before and this is my favourite of the 3 by far. Neutrik jacks, alpha pots, good trannies.....for the price these are unbeatable." Ben - 14 April 2012
Fuzz Face Kit - Clone 5 product stars
"If you're reading this you're obviously interested, so let me make this real easy... This is a superb clone kit with authentic tone reproduction; I bought the full ensemble, real quality components, professionally packaged and next day delivery from a reliable seller who cares enough to back it all up with first class after-sales service. Go on, not only will you enjoy the build, there's the added pleasure of great tones from a hand wired piece of kit..." Greg - 04 January 2012
Fuzz Face DIY kit 4 product stars
"Good fuzz kit, ALPHA Pots, good quality jacks. The fuzz was a little weak with classic combo AC 128 and also with 2N404 even combo, maybe my choice should have been for hotter trans! The 2 mini-caps could have been larger ones, there's enaugh room for better ones. Altogether a good quality kit for starters as I am; excellent instructions!" Daniel - 13 December 2011
