This new, all-tube, two-channel module brings the colossal, unmistakable roar of the classic Marshall JMP into the flexible, modern Synergy modular amplifier system, putting the sound that defined rock music directly into the hands of today’s guitarists.
The Sound of Rock, Finally Modular
The Marshall JMP amplifier—often associated with the famed Plexi era—is more than just an amp; it’s a piece of rock history. From the groundbreaking blues-rock of Jimi Hendrix and Eric Clapton to the hard-driving anthems of Jimmy Page, Eddie Van Halen, and Angus Young, the JMP tone is the bedrock of generations of guitar heroes.

“The JMP has always been about raw energy and expressive touch, and now players can access that authentic tone through the Synergy platform—without compromise,” a Synergy representative stated.
This partnership ensures that the crucial growl, touch sensitivity, and dynamic response of the original circuit are flawlessly captured, allowing players to dial in that iconic, cranked Plexi tone at any volume.
Uncompromising Features for the Tone Connoisseur
Designed for the most demanding players, the Synergy Marshall JMP Module is packed with features to replicate every nuance of the classic circuit:
- Real Tube Warmth: Dual 12AX7 preamp tubes ensure genuine, complex tube harmonics and response.
- Dual-Channel Flexibility: Two independent channels with full Volume 1, Volume 2, Bass, Middle, Treble, and Master controls for ultimate tonal shaping.
- Era-Specific Voicing: Dedicated 1960s and 1970s voicing switches allow guitarists to instantly capture the sound of different generations of JMP amps.
- Precision Treble Control: Four individual Bright switches offer fine-tuning of the critical high-end response.
- Cathode Select Switch: A crucial feature for accessing classic input tube configurations and feel.
- Innovative Dynamics: An exclusive “0-watt power amp” phase inverter design meticulously replicates the feel and dynamics of a fully cranked Marshall head, ensuring an authentic Plexi experience even at bedroom volumes.
