Teaching Machines FuzzBillion Distortion Device Pedal

Description

If you’ve ever wished your gain pedal had more buttons to twiddle, more tones to unleash and more sheer madness to explore, you’ll love the Teaching Machines FuzzBillion. This beast is a distortion playground for guitar, bass and synths — packed with numerical switches that let you sculpt gain far beyond anything a “normal” distortion box could ever dream of. Simply spin the numbers to jump from subtle low‑gain overdrive to full‑on screaming distortion and fuzz.
Totally analogue, totally bonkers!
Inside the FuzzBillion lives a zoo of clipping components (germanium, silicon, LEDs) all feeding through a left‑to‑right signal path that’s designed for deep, tweakable chaos. Change something early in the chain? It’ll reshape everything that comes after it.
Billions of combinations
This pedal isn’t just versatile — it literally has billions of possible settings. And don’t panic about changing up your fave, meticulously crafted tone. That’s because each sound corresponds to a physical number, so you can just jot down the combination or snap a pic with your phone and get your exact tone anytime. There’s even a dedicated space in the manual to store your favourite discoveries.
What does each control wheel do?
Here’s your guided tour of the FuzzBillion’s eleven numerical tone-shapers, from left to right. Each wheel turns using those delightfully clicky little plungers:
Wheel 1 (gain boost)

Positions 1–4 give you clean(ish) op‑amp boost tones.
Positions 5–8 unleash a gnarlier, gated transistor fuzz.
Setting 9 is an even more extreme version of positions 5-8, adding a second transistor in series.
0 is bypass.

Wheels 2, 3 & 4 (clipping amplifiers)
These three wheels shape the main clipping amplifier. Together, they transform the texture of the distortion in wonderfully weird ways:

Wheel 2 = more gain.
Wheel 3 = affects negative clipping (top of the waveform).
Wheel 4 = affects positive clipping (bottom of the waveform).

Wheel 5 (tone)

0 is the darkest and most bass-heavy.
1-8 increases in brightness.
9 removes the EQ entirely and gives you a passive level boost.

Wheels 6 & 7 (octave fuzz)
Octave fuzz works by flipping the lower half of the waveform, giving you that screaming octave-up effect.

Wheel 6 = octave fuzz drive.
Wheel 7 = blend amount.

Note: Wheel 6 only becomes audible when Wheel 7 is above 0.
Wheel 8 (PLL)
The phase‑locked loop is basically an oscillator trying desperately to follow your pitch. Different settings change how fast and how accurately it “locks on.” Expect glitchy, robotic, bizarre noises (but it needs a strong, high‑gain signal — otherwise it might do nothing at all).
Wheel 9 (bias offset)
This shifts the waveform up and down, causing intentional asymmetric clipping. It can sound chopped, broken, splattery or magically musical. Just give the circuit a few seconds to stabilise after changing the setting. 0 is the cleanest, most neutral bias point.
Wheel 10 (output clip)
Near the end of the signal path, this wheel adds a more traditional diode‑based clipping stage. It can reduce perceived gain while giving you longer sustain and smoother fuzz textures. It also interacts with everything that came before it — sometimes beautifully, sometimes brutally!
Wheel 11 (output tone)
A simple low‑pass filter:

0 = bypass (maximum treble).
1–9 = progressively darker.

Dial it back to taste depending on how feral things have gotten upstream. And that big red dial on the right of the pedal? That’s your master volume.Key Features
