Peavey Rock Master® Preamp Pedal
The Peavey Rock Master® Preamp Pedal delivers the iconic high-gain “Ultra” channel tone from the original Rock Master preamp, now in a compact and pedalboard-friendly format. Designed using Peavey’s advanced TransTube® technology, it recreates the feel, response, and saturation of classic tube-driven circuits while operating from a standard 9V supply.
With independent Pre and Post Gain controls, this pedal allows precise shaping of distortion and output levels, making it ideal for everything from tight rhythm tones to saturated lead sounds. The unique active EQ section — Bottom, Body, and Edge — provides extended tonal control beyond traditional EQ layouts, allowing players to sculpt their sound with exceptional detail.
Built for performance and reliability, the Rock Master® features a hard bypass switch with anti-click circuitry, ensuring clean signal integrity when disengaged. Whether used in front of an amp, into a power amp, or in a recording setup, it delivers the aggressive, punchy tone that defined an era of rock and metal.
