Electric Guitar Effects

The Peavey Rock Master is a stompbox-style guitar preamp, designed for 90s-style saturation and clean attack. It features TransTube technology, an active Bottom, Body and Edge EQ and dual Pre-Gain and Post-Gain controls for fine-tuning your sound. You can use it in front of your amp, a power amp or as a loop monitor, with a silent hard bypass.

ARTICLE N° 117909
The Peavey Rock Master uses the Ultra circuit from the Rock Master rack from the early 1990s in a compact format. It features a TransTube architecture powered by an internal 30 V boost from a standard 9 V power supply. This design allows you to retain dynamics even at high gain settings.

The Pre-Gain control adjusts the amount of input saturation while the Post-Gain adjusts the output level. Active Bottom, Body and Edge EQ act like a console section with precise cuts and boosts. The Mid Shift switch alters the frequency range of the Body control to tailor the midrange to your playing. A Gain Boost switch adds a useful notch of saturation for your solos or harder-edged rhythms. The hard-bypass includes an anti-click circuit for clean engagement on stage.

The pedal can be plugged directly into your guitar amp without complicating the chain. It can also be used in front of a power amp or in an effects loop. The 1 kOhm output impedance makes it easy to integrate with your modern or older rigs. The robust format remains stable on your pedalboard and withstands regular use. The controls respond quickly and make the nuances of your attack clearly audible.

This preamp is for guitarists looking for a structured rock and metal grain, inspired by historic Peavey sounds. It includes lab-validated EMC and FCC compliance for worry-free use.
