Marshall JMP-1 Tube MIDI Guitar Preamp

Sound Quality

Insofar as this unit sounds, well if you keep it at bed room levels it's not bad, this unit has an inherent 2k honk that you can't scoop out, very abrasive. I use a couple of 94 Strats with Duncans ,an Ibanez Pro-line with Dimarzios and a PRS Custom and could not get a sound that would useable live, unfortunately the noise floor for this unit is ridiculously high, if you are not using a gate (hush, Drawmer) forget it, the clean channel is just passable not much tone to speak of.


would I depend on this thing ya maybe, but then again it just takes up space in my rack now as I use an Egnater ie4, this unit is so damned limited that to get it going you are going to have to put a lot of pedals in front of the preamp(distortion, compression) as by itself it's just too weak

General Comments

Overall if it where lost or stolen I would not buy this unit, if anyone is looking for this kind of preamp go to e-bay and get an older Rocktron Progap much more useable sounds,as you've guessed I don't have much good to say about it, if you're 16 and starting out probably a good starter unit to learn on but other than that it's not for me,I have been playing for 35 years and I have a rack that takes two of my ugliest friends to carry, Egnater IE4,Furman pl-8, DTR-1000, Rocktron Intellifex Ltd, Rocktron Super C, BBE 362, Mesa Boogie 50/50 as a backup pre I use an older Progap and Marshall 80/80 for a backup amp, so believe me when I say get something else other than the JMP-1, just a nasty preamp
