Tone Bender Mk III

The final chapter in the classic Tone Bender series, and by far the most versatile.

Whereas previous TBs had only Volume and Fuzz controls, the MkIII adds a Treble-Bass (Tone) knob to take you from crunchy bottom-rich fuzz to all-out cat-bothering treble filth.

As Tone Benders always work better with PNP transistors, this latest FuzzDog offering has the option of an onboard voltage-inverter so you can use these cans but still daisy-chain your power with standard negative-ground pedals. This is totally optional. You can build it in posi-ground format and use a battery or dedicated PSU if you like, or just go for NPN cans. Leaving out the inverter requires a single jumper wire on the PCB. Simple!

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 only supplying AC128 or you can have the kit without cans if you want to source your own.

There are also a few circuit variations on offer, with slight differences in specs. These will be added when parts arrive.

The PCB has been designed for board-mounted vertical pots for minimal wiring and simple enclosure mounting, but you can wire them if you like. Note: the vertical pots offered with the kit have round shafts, so consider that when ordering knobs - you'll need some with grub-screw fitting. Normal pots can be wired or mounted with header pins if you'd prefer splined shafts for push-fit knobs.


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.

Sweet, smooth and vintage. 5 product stars
"I've had quite a few originals and this clone is spot on. Goes from thick and sweet to trebly chainsaw fuzz without ever going splatty. It's tight enough to do 70'ies power chords as well as garage punk fuzz bombs. Tons of overtones. Mobile phone taster here: https://www.youtube.com/watch?v=Xqg6B_VMTjo" Tjærand - 14/11/2014
