Rock Master Preamp Pedal
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.
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.
