Marshall JMP-1 Tube MIDI Guitar Preamp

"After the two effects we have about six amplifier outs. Two of the outs go to my Voodoo Modified JMP1 Marshall heads. The Voodoo mods make these amps amazing. They sound so much better than they used to. We have two of them: the main one is setup for Billy's main dirty sound and goes to the Marshall 120-120 power amps; the second Marshall JMP1 has a clean sound that goes to a direct box straight to tape for recording purposes because they record every night," says Billy Gibbons's guitar tech about the Marshall JMP-1 Tube MIDI Guitar Preamp.

A Marshall JMP-1 Tube MIDI Guitar Preamp appears in this Josh Klinghoffer rig rundown video.

1994 interview Guitar World - REZNOR: Almost everything was direct--there was almost no miking of cabinets. I just don't like that sound very much. It sounds boring to me. So we ran through a variety of preamps and speaker simulators. Our main preamp was the new Marshall JMP-1. But I didn't use the speaker simulator in it. I took the direct out of the Marshall into the Zoom 9030, employing just the speaker simulator on that.

"Dave's current rig consists of two JMP-1 preamps, two EL34 100/100 power amps, four PB100 Powerbrakes and eight 1960BV 4 x 12 cabinets."

In [this interview](http://www.emusician.com/gear/1332/signal-to-noise-the-sonic-diary-of-the-smashing-pumpkins/40242), it says, "He still had his Marshall 1960A cabinets, but Corgan shifted to a Mesa Boogie Strategy 500 and a Marshall JMP-1 preamp (Corgan also notes that he used an Alesis 3630 to drive extra gain into a Marshall)."

to quote the important part of the article in a verbatim manner: "For the second record, Thompson started using a Marshall JMP-1 pre-amp. Shortly thereafter, he came across the VHT PitBull Ultra Lead, which he switched to and used on the next few records."

“The whole thing started with the guitar riff,” Chris explains, “a big heavy metal-sounding thing. We basically got a click going, then we recorded the riff. I like tube gear, so I use a Mesa/Boogie TriAxis for the big sounds, and also a Marshall JMP-1 [both rack modules]. They’re the best sounding and most natural recording boxes I’ve found for guitar. I use a Line 6 Pod too, but more for the clean stuff.” For this track, the guitar was recorded through the TriAxis into a Neve mic pre, into a Yamaha 02R, and onto the Apogee Rosetta AD en route to Pro Tools. “I tend to use the Neve channel for guitars,” says Chris, “the APIs for drums, and the Summit TD-100s and GMLs for synths.”

"I'm pretty old school on the shit. For the studio I generally use my JMP Marshall rack mount which I've used since 1988 or '89 and then live, we recreate that sounds with a Blackstar head along with the aforementioned customized pedals which is arranged by my other guitar players which are also figuring out their pedals because I use my Eventide in the studio on their sound as well and then they have to figure out how to recreate it. That's the funny thing, as were going through a record and we're jamming or recording, were always having to think about how to recreate it. It's kind of a magical moment while it's happening..."

"Your live rigs have changed quite a bit since the late ’90s. Ken, you used to rely on a Marshall JMP-1 preamp and VHT 2150 stereo power amp into a Marshall 4x12, while Greg was using an Ampeg SVT II head with a matching 2,000-watt 8x10 loaded with David Eden speakers. Now you’ve both become big proponents of Fractal Audio Axe-Fx II modeling units running to the monitors and house systems," reads [this article](http://www.premierguitar.com/articles/22683-failures-monster-comeback?page=2).

"I’m still using the Diezel VH4’s and Marshall JMP1’s which are modded by Trace [Davis] at Voodoo Amps…" says Barry Stock, in [this interview](http://www.guitarworld.com/three-days-grace-guitarist-barry-stock-discusses-gear-and-new-album-human).

He likes combining the characteristics of multiple amps to achieve his tone, also using a Marshall EL34 100/100 and a Marshall JMP-1…"

"I use a POD direct, going through a spring reverb for the clean sound - and a Marshall JMP1 direct for the dirty. That's it - totally bare-bones. I know the guitar is a pretty visual instrument and all, but literally %95 of what I do in the band has to do with production, programming and keyboard arranging - there's very little time to fuck around with the guitar.

"When Chris re-joined W.A.S.P. for the KFD album and tour he was using Marshall JMP-1 preamps and Alesis Quadraverb 2 effects processors."

From the "Tech Talk" section of the old KMFDM website: Question (Jack): I am curious as to what Jules' main amp/effects setup is for live performances. Answer (Jules): At the moment I run a Marshall JMP 1 preamp going into the power amp section of a Peavey 5150 head

"with a Marshall JMP-1 Preamp"

What kind of equipment do you use? Guitars ... pick ups ... amps ...? Do you use different equipment in the studio and when playing live? If so, why? I have two guitars I use fixed. One is an Epiphone Les Paul and the other is an LTD CC 1000. Both are original. They have a slightly different tone, which gives me more possibilities in terms of sound. The amp I use is the same one I have used for almost 20 years. I have a Marshall JMP 1 preamp, Marshall JFX 1 processor, and a Marshall EL34 50/50 end stage. When playing live, I use Marshall Lead 1960 4x12 cabinets. In the studio I do not use speakers, but take the line signal from JMP..n right in the table.
