About this listing
Marshall JMP-1 Valve MIDI Guitar Preamp Rackmount Tube Preamp w/ Speaker OutOffered here is a Marshall JMP-1, one of the most iconic rack mount guitar preamps ever produced. Combining genuine Marshall tube tone with full MIDI programmability, the JMP-1 became a staple in professional touring and recording rigs throughout the 1990s and remains highly sought after by guitarists today.Powered by a pair of ECC83/12AX7 tubes, the JMP-1 delivers four distinct channels covering everything from pristine cleans to classic British crunch and high-gain lead tones: • Clean 1 – Warm, full-bodied clean tones with excellent headroom. • Clean 2 – Bright, articulate cleans inspired by the legendary JTM45. • OD1 – Classic Marshall crunch with rich harmonics and smooth saturation. • OD2 – High-gain lead channel with tight low end, sustain, and modern aggression.Designed for maximum flexibility, the JMP-1 features full MIDI In, Out, and Thru connectivity, allowing instant preset recall and seamless integration into complex rack systems. A programmable stereo effects loop, stereo line outputs, and speaker-emulated outputs make it equally at home on stage, in the studio, or as the heart of a modern recording setup.Features • Marshall JMP-1 Valve MIDI Guitar Preamp • Genuine Tube (ECC83/12AX7) Preamp Design • Four Fully Programmable Channels • Classic Marshall Clean & Overdrive Tones • Full MIDI In / Out / Thru • Programmable Stereo Effects Loop • Stereo Line Outputs • Speaker-Emulated Outputs • 1U Rackmount ChassisConditionThis unit is previously owned and shows cosmetic wear consistent with normal use.
