## What is it?
Warm Audio released a take on the fOXX Tone Machine, a carpeted octave-fuzz used by Billy Gibbons, Beck, Peter Frampton and others.
## Design collaboration
Dan Auerbach helped design the Peach Fuzz with Warm Audio, using his Black Keys experience to create a pedalboard-friendly version.
## Key features
The Peach Fuzz has a switchable latching/momentary dual-footswitch setup, volume, sustain, and octave controls for creative sound manipulation.
## Build quality
The Peach Fuzz uses NOS 2N3565 Fairchild transistors, Germanium 1N34A diodes, carbon resistors, and premium film capacitors for authentic vintage fuzz.
## Sounds
The Peach Fuzz delivers a swooshing tide of saturation with a range from square-wave woof to sharper wasp-like tones.
## Peach finish
The peach-pink finish is soft to the touch but prone to stains and may look mucky over time.
## Price and specs
The Peach Fuzz costs $199, has true bypass, 9V DC or battery power, and dimensions of 140mm x 84mm x 58mm.
## Usability
The Peach Fuzz has a switchable octave effect and momentary/latching modes for the octave effect, making it practical for pedalboards.
## Sound transformation
The Peach Fuzz can transform electric guitar tones into horn parts or synth-like sounds with its octave-up effect.
## Verdict
Warm Audio and Dan Auerbach improved the classic octave-fuzz with a pedalboard-friendly design and octave control.

> We'd never done a pedal, but when we were talking about what fun things to do for the album Peaches, we were talking about pedals.
## Key takeaway

Warm Audio and Dan Auerbach improved the classic octave-fuzz with pedalboard-friendly design and octave control.
