The Warm Audio The Black Keys Peach Fuzz is a fuzz pedal made by Warm Audio, based on the Foxx Tone Machine octave fuzz. It is listed as The Black Keys Signature Peach Fuzz at £199 GBP1. Warm Audio describes it as "a small but mighty fuzz pedal that goes from mellow to mayhem real quick", based on the company's vintage-inspired '70s Foxy-style fuzz and octave circuit2.
The controls and footswitches
The Peach Fuzz carries three knobs and two footswitches, plus a mode switch for the octave function1:
| Control | What it does |
|---|---|
| Volume | Dials in the output level |
| Sustain | Sets the fuzz sustain |
| Fuzz | Sets the fuzz amount |
| Latching / Momentary switch | Selects whether the octave hold engages latching or momentary |
| On/Off footswitch | Bypasses and engages the pedal |
| Octave Sustain footswitch | Engages the selectable octave-up hold |
Warm Audio sums up the range of the three knobs as "Volume, sustain, and mellow-to-brite tone controls make it easy to dial in everything from low-gain grit to thick, seari[ng]" fuzz tones2. Guitar Pedal X lists the full control set as "Volume, Sustain, Fuzz, Latching / Momentary Switch, On/Off Footswitch, Octave Sustain Footswitch"1.
The Octave Sustain footswitch is the pedal's distinguishing feature: Warm Audio markets the pedal as "The Black Keys Fuzz Guitar Pedal With Selectable Octave-Up Hold"2, meaning the octave-up effect can be held on or engaged only while the switch is pressed, depending on the latching or momentary setting1.
Where the circuit comes from: the Foxx Tone Machine
The name, the signature and the Frantone question
The Peach Fuzz name was already taken before Warm Audio used it. Guitar Pedal X points out that "the Peach Fuzz exists already - and that is a legacy pedal from Frantone!", and is explicit that the Warm Audio pedal is "no not a take on the famous legacy Frantone Peach Fuzz, but rather a Flocked Peach-colour take on the Foxx Tone Machine"1. The Frantone Peachfuzz was among the pedals Frantone was famous for, alongside the Cream Puff3. The same Guitar Pedal X writer found the Warm Audio pedal "a little over-sized for my preferences, but functionally pretty smart", and notes the name clash with the Frantone pedal overall1.
The signature side of the pedal is straightforward: Warm Audio states that "The Black Keys Peach Fuzz is a collaboration between Warm Audio and The Black Keys' Dan Auerbach"2, and Guitar Pedal X covered the release as "the Black Keys' Dan Auerbach signature Peach Fuzz"1.
The enclosure and what is inside
The finish is the most visible thing about the pedal. Warm Audio says it is "Covered in thick flocked velvet in a special Peach color to celebrate the 2026 Black Keys release, Peaches!"2, and Guitar Pedal X likewise calls it "A cool peach flocked enclosure take on the Foxx Tone Machine"1. The special Peach color is tied to the 2026 Black Keys release Peaches!2.
Inside, Warm Audio specifies:
- Germanium 1N34A diodes2
- Carbon resistors2
- Premium film capacitors, which the maker says deliver "authentic vintage fuzz"2

Questions
Is the Warm Audio Peach Fuzz the same as the Frantone Peach Fuzz?
No. Guitar Pedal X notes that the Peach Fuzz name already belonged to a legacy pedal from Frantone, but the Warm Audio pedal is not a take on it. The Warm Audio Peach Fuzz is instead a peach flocked take on the Foxx Tone Machine octave fuzz circuit, released as a signature pedal with Dan Auerbach of the Black Keys.
What does the Octave Sustain footswitch do on the Peach Fuzz?
The Peach Fuzz is described by Warm Audio as a fuzz pedal with selectable octave-up hold. It carries a dedicated Octave Sustain footswitch alongside the On/Off footswitch, and a switch that selects between latching and momentary operation, so the octave-up effect can be held or engaged only while the switch is pressed.
Is the Warm Audio Peach Fuzz a Dan Auerbach signature pedal?
Yes. Warm Audio describes The Black Keys Peach Fuzz as a collaboration between Warm Audio and The Black Keys' Dan Auerbach, and Guitar Pedal X covered it as the Black Keys' Dan Auerbach signature Peach Fuzz when it was released in October 2026.
What is the Foxx Tone Machine?
The Foxx Tone Machine is a 1970s fuzz and octaver pedal. RockBoard's PedalPedia calls it one of the most expressive and more extreme fuzz boxes of the era, and TONEHOME describes the fOXX Tone Machine as the funky, fuzzy coated fuzz pedal. Warm Audio, Danelectro and Stomp Under Foot have all released their own versions of the circuit.
What is the Peach Fuzz enclosure made of?
The enclosure is covered in thick flocked velvet in a special Peach color, which Warm Audio says celebrates the 2026 Black Keys release, Peaches! Inside, the pedal uses carbon resistors, premium film capacitors and Germanium 1N34A diodes.
