Marshall JMP-1 Tube MIDI Guitar Preamp

Sound Quality

I play a Gibson Flying V, Ibanez Jem7VWH, B.C. Rich Mockingbird Supreme and a PRS Custom 24. I pretty much always use humbuckers. My new rig contains a Furman PL-8II, Marshall JMP-1, T.C. Electronic G-Force, BBE 482i Sonic Maximizer and a Marshall EL34 100/100 (I first ran my JMP-1 through a Marshall 30th Anniverary head for power), then through two Marshall 1960B cabs. On the floor I use a Ground Control Pro for MIDI switching, an Ernie Ball volume pedal and a Crybaby 535Q. It's a deadly setup!!! There is a little noise when using alot of overdrive but the gate in the G-Force keeps that under control. This preamp is very versatile although the clean sounds aren't the greatest, remember it's not a Fender or a Mesa/Boogie, but with a little help once again from the G-Force it makes the clean tones sound alot better. The overdrives sound are amazing, especially when using a sonic maximizer. I'd give it a 9 if the clean channels were warmer...


Haven't had any problems yet.

General Comments

Ive been playing guitar for 11 years now. I also own a Mesa/Boogie Studio .22+ combo, a Marshall 30th Anniversary head and a Sansamp PSA-1 preamp(for recording). I was considering buying a Triaxis and am now glad I didn't due to the fact that there is a huge price difference(especially here in Australia) and the JMP-1 can do nearly everything the Triaxis can. If it were stolen I would buy it again unless Marshall brought out a JMP-2!
