A Pedal Worthy of a Legend

The Pedal of Doom is the result of 18 months of design, testing, and collaboration, created to honour the legacy of Geezer Butler. Inspired by his unmistakable tone and the spirit of classics like Hand of Doom, this signature pedal gives bassists the power to summon the crushing depth and rich harmonics that defined a generation.

Dual EQ for Ultimate Control

At the heart of the Pedal of Doom lies its switchable dual EQ system, giving you complete flexibility to craft two unique tones. With bass, low-mid, hi-mid, and treble controls for each channel, plus a shared treble, you can tailor you sound with surgical precision. Whether stacking subtle layers or unleashing full sonic chaos, you have full command of your EQ before and after the drive.

Distortion That Brings the Doom

With a switchable drive circuit, the Pedal of Doom delivers everything from warm, vintage-style growl to a wall of devastating distortion. Its gain structure lets you dial in the perfect amount of grit or doom-laden saturation, letting you move seamlessly between musical subtlety and bone-crushing heaviness.

Professional Features, Rock-Solid Build

Engineered in Essex, the pedal is housed in a rugged 1.6mm Zintec steel chassis with a 0.9mm alloy over panel for maximum durability. Dual VU meters give you real-time monitoring of your input and output signals, ensuring balanced gain across your chain. A transformer-based balanced DI output makes it easy to connect directly to front of house or studio gear, while a ground lift switch ensures noise-free performance.

Geezer's Seal of Approval

Before release, the pedal was personally tested by Geezer Butler himself, and he verdict was clear: "This is without a doubt the best sounding and engineered pedal I have ever played, and with my amp, it truly has the sound of doom I live for."
Backed by Geezer's endorsement, the Pedal of Doom stands as a testament to Ashdown's commitment to delivering uncompromising tone for serious bass players.
