When rock legends needed that earth-shaking roar, they cranked their Marshall Plexi amps to eleven. Now, Synergy and Marshall have bottled that lightning in a preamp module that delivers the growl, bite, and soul of a cranked JMP at any volume. This isn't just another preamp — it's your direct line to the sound that built rock 'n' roll.
The JMP module packs serious punch with its dual-channel design and innovative "0-watt power amp" circuit. Think of it as fitting an entire Marshall stack into a compact module that sits perfectly in your rack or modular setup.
The JMP module doesn't just sound like a Marshall — it feels like one. The touch-sensitive response means your playing dynamics come through crystal clear, whether you're digging in for aggressive rhythms or backing off for clean passages.
This module captures every nuance of the original JMP circuit while adding modern flexibility that touring musicians demand.
The JMP module isn't just about specs and circuits — it's about plugging into the same sonic DNA that powered Hendrix's feedback symphonies, Page's thunderous riffs, and Van Halen's groundbreaking solos. Whether you're laying down tracks in the studio or commanding the stage, this module delivers the legendary Marshall tone that's been the backbone of rock for over half a century.
