Tone Bender Pro MkII

All-time classic fuzz. Huge, smooth sounds available from this great circuit. Super-saturated lead tones, or great chord work with the guitar volume knocked back.

The choice of transistors will grow as more experimentation and fiddling goes on at FDHQ. There's plenty of room on the board to take the meatiest of vintage cans. Right now we're offering a combination of Russian germaniums and others we have in stock, Newmarket CV7007 (OC77), or you can have the kit without cans if you want to source your own.

You can even swap a couple of components and make yourself a Marshall Supa Fuzz (much fatter, bassier tone than stock) or a Vox Tone Bender MkII (slightly bassier, not a lot).

The circuit has board-mounted pots for minimal wiring and simple enclosure mounting.

Would qualify as easy but you need to adjust two trim pots to bias the transistors. A multimeter is recommended, though you can do it by ear.

Use in conjunction with a Power Pump or the charge-pumped daughterboard if you want to power the PNP version on your standard polarity daisy chain.


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.


Inspired by: Tone Bender MkII

Difficulty: Easy-Medium

PCB size: 50 x 22mm

Knobs required: 2

Enclosure: 1590B

Direct-Connect compatible (4-way)

A revelation 5 product stars
"Bought this on a whim, so I could brag that I've been through all numbers of transistors in a fuzz / vintage-style pedal (I've tried: Rangemaster (1 transistor), Fuzz Face (Si and Ge), Harmonic Percolator, Fuzzrite (so far just Si, also from FuzzDog) (2 transistors), and Big Muff variants (4 transistors)), but this is my first 3-transistor fuzz, and I love the sounds it makes. The transistors were carefully picked out by FuzzDog, proper hFE and all and nicely marked. I really didn't expect the pedal to sound so good. It even cleans up quite nicely with the guitar volume knob, not quite as well as a Ge Fuzz Face but still great with it's own character. Couldn't recommend this pedal more. Be careful of the positive ground thing though, I first went on autopilot and soldered the LED in the usual way, then had to replace it with another one in order to revert the legs (short leg goes to round pad this time)."

Greatest fuzz I ve ever heard 5 product stars
"The only caveat I ll make is that different transistors and different bias setting could yield different results. That said, this is the greatest fuzz pedal I ve ever used. With the knobs turned up, it s insanity. If I set them just right, I can get clean up from the volume knob with a very strong fuzz with the volume back up. Mind blowing stuff. Easy to build if not for having to take care with the wiring polarity. Read and re-read if like me you re a bit of a novice." Alex - 30 June 2020
Excellent fuzz! 5 product stars
"Built the TB MkII variant with Fuzz Dog's AC128 transistors - which were numbered for Q1,2, and 3. Built battery only for simplicity and mojo points. Biased the transistors for a smooth, full fuzz - rolling off the guitar's volume control gives more control of the fuzz than the attack knob, but even that has its use! A fantastic fuzzbox full of vintage tones. Thanks, Fuzz Dog!" Ian - 27 March 2019
TB Pro MkII Supa Fuzz. 5 product stars
"Bought the Supa Fuzz variant. Results as with other reviews are that this is a VERY good pedal. I would recommend this pedal type to anyone interested in getting 'that' sound without breaking the bank. My advice: follow all the tips from Fuzz Dog. If necessary, practice your soldering before hand. Use a good quality fine tip iron. Most important if your a bit rusty is don't rush. Double check the components as you go. Worked for me first time. Will be coming back for more at some stage." Steve - 19 November 2015
Gorgeouzzz 5 product stars
"Assembles very well, paying good attention to the hints in the instructions. For me it all worked at first attempts, both preliminary test connections and final mount. The pedal feels like "heavy duty" and the sound is simply gorgeous. A bit dry with my initial settings (90K for Q2 and 8.2K for Q3). I will leave it there for a while, since I just bought a Vox AC30 and I have to get familiarized with the amp too before fiddling with the Tone Bender." Mikael Berger - 11 February 2015
...victory, is mine (all mine) 5 product stars
"I haven't touched any of my other fuzz pedals since I built this kit...and I see no reason to. This is it. The sound is amazing and rich with harmonics. The kit is easy, and Lee is very helpful (for those times of "user error"). I'd be tempted to say that it's idiot proof. At least this idiot managed to pull it off, and is very happy as a result." Erik - 15 April 2012
