The Groff Firestorm Distortion is a high-octane tone monster capable of delivering loads of gain and level boost while remaining smooth and refined. The beautifully voiced tone stack ensures you can cut through the mix and is never thin or brittle. Flexible EQ and clipping options means it can be dialed in to play nicely with your rig and personal tastes.

Based loosely on the original Marshall® Guv’nor, we’ve added plenty of updates and tweaks to make this pedal unique and flexible.

The “Clip” switch allows you to select between three diode combinations, dramatically changing the changes the dynamics and character of the pedal.

LED Clipping delivers crisp mid-driven ‘800’ crunch tones with loads of gain and headroom.
SI Clipping uses 1N914 silicon diodes for more saturation and a smoother breakup.
GE Clipping uses 1N270 germanium diodes for a warmer, harmonically rich distortion tones.

A “Bass” switch modifies the low-pass filter, and increases or decreases the bass response of the pedal, allowing you to match the pedal to your amp and musical style.

Each Firestorm pedal is hand-built in Lancaster, PA and finished with a rugged aluminum enclosure, Neutrik jacks, Alpha pots, a soft-touch relay true-bypass footswitch, and a beautiful hammertone finish.

Backed by a 5-year limited warranty.
