Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement. Shown only within a gear class, and only where there's enough evidence to be meaningful.52% — moderately similar

The Mad Professor Stone Grey Distortion is a high-gain distortion pedal with Volume, Distortion, and Tone controls, the Tone acting as a boost/cut shelving EQ similar to a bright switch. It is built to retain note clarity and a tight low end even at extreme gain, staying usable on extended-range guitars such as seven, eight, and nine strings without turning to mud. Lower Distortion settings behave more like an overdrive, while higher settings deliver a fierce, high-gain attack, making it a distortion pedal that can also function as an overdrive rather than only excelling at one end of the gain range. It is designed to add drive on top of an amp's own voicing rather than overriding it.
The Vox Valvenergy Cutting Edge is a tight, high-gain metal distortion pedal built on Vox's Nutube technology, designed to deliver focused, aggressive gain with genuine tube-driven harmonic response rather than the flatter character of typical solid-state high-gain pedals. It targets a tight, cutting metal voicing specifically, distinguishing it from the smoother, more vintage-amp-inspired pedals elsewhere in the Valvenergy lineup like the Silk Drive. As part of the original Valvenergy quartet, it shares the series' Nutube-driven approach to authentic tube dynamics in a compact, low-maintenance format.
