The Rock Master® Legacy, Reborn
Our original Rock Master® preamp became a favorite for its fire and flexibility. This pedal brings that voice back in an easy-to-use format.

Active EQ, Wider Range
Bottom, Body, and Edge controls cut or boost like a pro mixing console, giving you precise tonal control far beyond a standard EQ.

Tube-Era Feel, TransTube® Tech
The Rock Master® Preamp Pedal captures the character of the Ultra channel using Peavey’s TransTube® circuitry engineered to deliver authentic tone and touch from a standard 9V supply.

EQ That Goes Beyond Treble, Mid, Bass
Bottom, Body, and Edge controls give you a broader tonal palette than a standard EQ — precision shaping that matches the original Rock Master® design.

Dynamic Range Without
Limits
With stepped-up 30V rails, the Rock Master® Preamp Pedal delivers the headroom high-gain players need, keeping your tone tight and powerful at any level.
