SynergyMarshall JMP 2-Channel Tube Preamp Module - Black
1/15
Independent shopping perspective
The Korena take
Built for a Synergy preamp-module dock, the black Marshall JMP module puts two independently controlled tube channels into a compact rig format. Volume 1 and Volume 2 recreate the Bright and Normal input blend, while each channel gets its own three-band EQ and Master control for setting separate rhythm and lead levels. Four Bright switches, selectable ’60s or ’70s voicings, and a three-position Cathode Select switch provide further adjustment. Its 0-watt power amp circuit includes a phase inverter and transformer.
Strong match
Who this is for
- Setting separate rhythm and lead levels with independent channel Master controls.
- Stage, studio, or home rigs built around a Synergy preamp module dock.
- Blending the Bright and Normal-style volume controls to adjust attack and body.
Consider the trade-offs
When to look elsewhere
- Rigs without a compatible Synergy preamp module dock.
- Players who need more than two channels from one preamp module.
