Description
The Peavey Rock Master Pre-amp is your ticket to the legendary high-gain tones of the '90s, now in a portable pedal format. This powerhouse preamp brings the iconic Rock Master Ultra channel to your feet, offering a dynamic saturation that emulates the feel of a cranked tube amp. Whether you're aiming for tight rhythm crunch, searing solos, or aggressive modern sounds, this pedal serves as a versatile foundation with authentic Peavey flair.
At the heart of the Rock Master is Peavey's TransTube analog circuitry, which captures the snarling gain structure and tightly focused mids that defined an era of hard rock and metal. Its twin gain-stage architecture, with both Pre- and Post-gain controls, lets you fine-tune your attack and sustain with pinpoint accuracy. Complemented by a 3-band EQ labeled Bottom, Body, and Edge, the pedal offers musical, amp-like tone shaping that integrates seamlessly into any rig.
Designed for serious use, the Rock Master features a rugged die-cast chassis and high-quality components, ensuring durability on stage and in the studio. A true hard bypass switch with an anti-click circuit preserves your signal chain when the pedal is disengaged. This pedal isn't just a tribute; it's a genuine piece of Peavey's legacy, built with the same analog design principles as the original rack unit.
