ItвЂ™s many tones are all valve generated and presented in a way that is both comfortable and familiar to guitar players. During that time, Ive heard all sorts of rumours and stories about this preamp. Your JMP-1 MIDI pre-amp is a carefully designed coalescence between modern MIDI technology and classic Marshall valve circuitry. The Traixis was much better for clean tones, had a wider pallette of distortion tones but could not do the marshall distortion thing like the JMP 1. Ive been using JMP-1 preamps since they were introduced in the 90s. The JMP 1 was okay for clean guitar sounds but was good-ish for mostly distorted sounds. I still use midi via midi controllable mixers, and I get my distortion sounds off a custom made 1U rack unit by OM labs. The triaxis was better for clean bass but not as good as a dedicated bass preamp either.Д®ventually I sold both and started to use fender showman based bass preamps for guitar: they were cleaner, quieter, had tons of headroom, and did the fender thing. The Marshall JMP-1 is a rack-mount pre-amp that includes the ability to model four different Marshall tones and emulate stereo sound.

Tried both on bass, passable sounds but low end roll off on JMP 1 and not to me, a useable sound unless for specific effect. This great sounding, 1 rack space, easy to use and program, 4-channel preamp offers instant recall of your 100 favorite settings. I used it in my guitar rack which also had a triaxis.

The Marshall JMP01 Preamp was designed by a team of guitarists who think exactly as you do. I had one for a long time, since they came out till about 2005. Purchased to manage easily on stage and at the foot a lot of different sounds by subscribing via the multi-effect noon JMP1 and avoid invasive pedalboard.
