MXR Custom Shop Brown Acid Fuzz Pedal

Dripping in Sludgy, Heavy Tones

Written by

Cian Hodge

Psychedelia is back and in full swing in the world of the MXR Custom Shop Brown Acid. This trippy fuzz pedal is geared towards heavy guitarists and bassists alike, who favour large amounts of gain and heavy grooves.

It’s based on a classic ‘70s British fuzz circuit and delivers characterful gain in the bucketloads. If you like a bit of stoner rock or doom metal, this is the stompbox you’ve been looking for.


There’s not much to be said about the three-band control layout, consisting of an output, tone and fuzz intensity. Whatever you dial in here, you’re guaranteed unmistakeable vintage-tinged tone - think Queens of The Stone Age.

Load up on the intensity control for thick, gripping fuzz or back off slightly and up the tone for snarling transparency and fast attack.

Limited Edition

The Brown Acid is of course an MXR Custom Shop pedal, meaning there are only limited amounts in production. Famous Bay Area artist Alan Forbes designed the artwork for the pedal – you’re getting something truly unique here.

Act quick and get one before they sell out.
