Pitbull - Highly tweakable Silicon Tone Bender

Tone Benders. Gotta love them. But just like the Fuzz Face name lends itself to two vastly different beasts, so must the TB. It's the law.

We all know and love the germanium-based TBs, but there's always room for some silicon action, and here it is.

Mic Tester's original SiTB circuit is the raw material for this tweak-fetishist's dream, with some all-important controls placed externally. As well as your normal Vol, Gain and Tone you have complete control over how fat the input cap is, the bias, and there's an optional starve control. Starve and Bias? Isn't that a bit of an overkill? Nope. Try it - you just might like it.

Huge, fat fuzz or splattery, gated dying battery fun - it's all there.

Designed for vertical board-mounted pots, or you can wire up 'normal' ones if you prefer. If you opt for the recommended vertical-mount pots remember they have round shafts, so you'll need knobs that fix with a set screw. Spacing is tight (18.5mm apart), so you'll need small 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.

Builds are only available with full kits including enclosures. Please choose appropriate knobs.

Difficulty: Medium

PCB size: 50 x 36mm

Great versatile fuzz, very well laid out, almost perfect! 4 product stars
"Well, I didn't know which Tone Bender was the best, and this one does it all! As with all the kits from Fuzz Dog, the PCB is terrific, and the component selection speeds up the process a great deal. (There was just a resistor with the wrong value, which was quickly solved with 0 02 at the local electronics shop). Everything else was ready to solder, and the painted and drilled Hammond box was spotless. The finished pedal looks flawless and sounds great. The "volts" knob is a nice addition. It allows the normal use of the pedal at full throttle, yet at lower supply voltages it enters the domain of lower levels of distortion and... oscillations! This one does some of the interesting sounds of the Fuzz Factory, which you can control with the guitar's tone and volume knobs. All this with a ton of usable fuzz and distortion tones. I couldn't have asked for more. Great design! The only drawback is that, if set to oscillate, the pedal will bleed the oscillation noise when in bypass. This may be a byproduct of the optical bypass, so I wouldn't advise anyone to get it, if you aim to use this for the crazy sounds." Manuel S - 09/07/2017
