Peavey® Rock Master Guitar Preamp Pedal

The Peavey Rock Master® Preamp Pedal revives the fire and flexibility of the original Rock Master preamp in a compact, pedalboard-friendly format. Long favored by players for its wide tonal range and powerful gain structure, the Rock Master returns with the same unmistakable voice—now designed for modern rigs and easy integration.

Capturing the character of the legendary Ultra channel, this pedal uses Peavey’s TransTube® circuitry to deliver authentic response, touch sensitivity, and amp-like dynamics from a standard 9V power supply. Its unique Bottom, Body, and Edge controls function more like a professional mixing console than a traditional guitar EQ, allowing precise cut and boost across key tonal ranges for deeper sculpting and clarity.

With a broader tonal palette than a standard EQ, the Rock Master Preamp offers refined shaping that mirrors the original design—making it equally at home pushing a clean amp, running direct, or serving as the core tone engine on a pedalboard.
