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.33% — somewhat different

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 Revv Chat Breaker is a boost and distortion pedal from Revv Amplification, delivering the tone-shaping and gain capability of Revv's amplifier circuits in a compact, high-quality pedal format. Revv Amplification is known for translating their acclaimed tube amplifier channel designs into pedal format.
