Bigfoot Engineering King Fuzz

The Bigfoot Engineering King Fuzz is a high gain guitar pedal that covers a range of fuzz and distortion tones in one box. Bigfoot designed it to sound and respond exactly like a cranked up vintage tube amp, covering everything from medium gain blues to fully saturated rock and everything in between¹.

The design brief came from a specific player's sound: RockBoard's PedalPedia says the pedal is inspired by the organic guitar tones of Dan Auerbach of The Black Keys¹. Auerbach has a documented history with fuzz pedals; British Pedal Company lists him as a "Classic Fuzz Collector" who picked up one of their Shatterbox pedals², and in 2026 Warm Audio released a Dan Auerbach signature Peach Fuzz pedal³.

A cranked-up tube amp in a pedal

The idea behind the King Fuzz is amp-like behavior rather than a fixed fuzz character. RockBoard's PedalPedia describes it as a high gain pedal that covers a multitude of fuzz and distortion tones, designed to sound and respond exactly like a cranked up vintage tube amp, from medium gain blues to fully saturated rock¹.

That amp-like responsiveness is what reviewers picked up on. MusicRadar's Michael Astley-Brown found the pedal reacts to the instrument itself rather than sitting on top of it⁵:

In practice, that means rolling back your guitar's volume knob cleans the pedal up, and your guitar's tone control shapes the top end, the way a tube amp would respond⁵.

Controls: two knobs, no tone control

The King Fuzz keeps its panel minimal. MusicRadar notes the pedal has only two controls, gain and volume, but with a huge range on both dials⁵.

There is no tone knob. MusicRadar's reviewer did not miss one, finding the pedal voiced just right and highly responsive to the tone and volume adjustments on the guitar itself⁵. If you like shaping fuzz from the instrument rather than the pedal, that suits the design; if you want onboard EQ, you would need to look elsewhere.

Power, bypass and build

The King Fuzz is true bypass, so your clean signal passes through untouched when the pedal is off, and it accepts battery or adaptor power⁵. The maker's specifications list 9V DC center negative and a 5mA current draw¹, which is light enough that it will not strain most pedalboard power supplies.

The pedal is made in Britain, and MusicRadar notes that buying from Bigfoot ensures a lifetime guarantee⁵. Bigfoot Engineering is based in West Sussex, England⁴.

The King Fuzz Mini

Bigfoot also makes a King Fuzz Mini. according to RockBoard's PedalPedia, the circuits and tones are identical in the Mini to the standard King Fuzz pedal, so it is a size reduction rather than a different sound⁶.

The Mini is also an analog circuit⁶, so players choosing between the two sizes are choosing between enclosure size and battery power, not between two different sounds.

The King Fuzz XL: two pedals in one

There is a third size in the family, the King Fuzz XL. On That Pedal Show, the presenters explained that the XL is actually two of Bigfoot's pedals in one enclosure: a Thunder Pup overdrive and a King Fuzz distortion, switchable between two settings⁷. The two sides cannot be stacked, so you run one or the other at a time⁷.

Premier Guitar reviewed the XL in 2023 and called it a fuzz/overdrive/distortion combo, with a range running from always-on, warm-and-mellow boost tones to colorful, organic crunch to scathing and blazing fuzz sounds. Their reviewer found it beautifully built and worth the investment to many despite the high price⁸.

On That Pedal Show, the presenters characterized the King Fuzz side of the XL as the more modern-sounding of the two⁷.

Where it sits among fuzz pedals

The King Fuzz is a two-knob, amp-response fuzz/distortion pedal rather than a clone of a vintage circuit. Players comparing it against other compact fuzzes will find the market full of alternatives with more knobs, such as the King Tone Guitar miniFUZZ, which adds a bias control, a three-way voicing toggle and DIP switches⁹. The King Fuzz takes the opposite approach: fewer controls, with the tone shaping done from the guitar.

For a player chasing Dan Auerbach-style tones, the King Fuzz is one of several routes. Auerbach's own signature fuzz, the Warm Audio Peach Fuzz, was released in 2026³, and his fuzz collection is documented by British Pedal Company². The King Fuzz is the pedal Bigfoot built around that inspiration.
