Synergy Synergy Marshall JMP All-Tube Preamp Module
Description
Presenting the all new Synergy Marshall JMP All Tube Preamp Module for use with Synergy modular amp/preamp setups. Prepare to harness the sound that built rock and roll. Marshall and Synergy have joined forces to bring you the Marshall JMP SYNERGY preamp module, transforming the legendary JMP amplifier into an all-tube, stage, and studio tool for modern players and engineers. Combining Marshall’s historic circuit design with Synergy’s cutting-edge modular technology, this module delivers the unmistakable growl, touch sensitivity, and dynamic response of a cranked JMP—at any volume. Key Features for the Modern Player: Authentic All-Tube Tone: This preamp module is based on the legendary Marshall JMP "Plexi" amplifier, featuring two 12AX7 preamp tubes to ensure rich harmonic performance. Built-in Power Section: The onboard phase-inverter and Zero-Watt Power Amp circuit bring all the tone and functionality of a Class-A Tube Power Amplifier directly into the module, ready for desktop, studio, or stage use. Dual-Channel Versatility: The JMP module features two identical channels, each with independent Bass, Middle, Treble, and Bright controls. Use the independent channel Volume controls with the Master Volume to recreate the popular "Input-Jumping" sound of the original Plexi. Vintage ERA Switching: A dedicated '60s/'70s switch per channel lets you dial in the exact tone you need: '60s Mode: Delivers a rounder, smoother JMP tone with a fatter bottom end. '70s Mode: Provides a tighter, more aggressive response, perfect for capturing the evolving sound of rock. Customizable Feel: A three-position CATHODE SELECT switch on the PCB allows you to configure the input tube bass response to match specific vintage circuits, affecting the feel and tightness of the amplifier. The module is preset to position 1, but you can experiment to find your ideal tone. Seamless Integration: Designed for easy installation and removal from any Synergy preamp dock, making it a perfect addition to your existing rig. Synergy hardware and interchangeable preamps are protected under US patent.
