PRELOVED Mad Professor Stone Grey Distortion (Custom Edition)

PRELOVED Mad Professor Stone Grey Distortion (Custom Edition) – Excellent Condition

The Mad Professor Stone Grey Distortion is one of those pedals that quietly earns a loyal following. Designed for players chasing articulate, amp-like gain, it delivers a smooth, harmonically rich distortion that sits right in that sweet spot between classic rock drive and modern high-gain clarity.

This Custom Edition version offers a refined voicing with excellent note definition, even under heavier gain settings. Chords stay clear, single notes sing, and it responds beautifully to your picking dynamics and guitar volume — making it a strong option whether you’re playing rhythm or lead.

Unlike harsher distortion pedals, the Stone Grey keeps things balanced. There’s plenty of gain on tap, but it never loses its musicality. It pairs especially well with clean or edge-of-breakup amps, giving you a consistent, usable tone across a wide range of styles.
