Michael Nielsen which outputs have you used for this demo ? Master or speaker emulator ? Thanks for the demo ! 👍🏻

[@BigHairyGuitars]

@@Alain.Bilodeau The "direct" bits are from the speaker emulated out. The part that's running through the VHT power amp are using the master out.

They were in the Leppard racks until we switched to the AxeFx 3 in early 2018. Phil’s signal chain was JMP into AxeFx 2 direct to FOH. Phil’s were stock, Viv’s were modded by Trace at Voodoo. Great units!

[@spy590]

So random that I found this 2 year old comment…I saw Leppard in ATL earlier this week, and they sounded killer! I was curious about their gear since the guitar tones were incredible. I found an old rig down with JMP-1/AxeII combo, then remembered Mike did this video, and here we are! I hope you are still touring with them-great show! Edit: I would love to know more about their AxeIII presets, if you are able to share. Cheers!

You've had this thing this entire time!!! I feel like our entire friendship has been a lie!

[@gstmusic69]

LOL

[@LeonTodd]

Hearing the demo at the start I thought "that sounds way better than mine ever did, he's probably getting some extra flavour from the VHT". But it's DIRECT!

[@mkii1964]

Leon Todd thought the same thing, lol

[@81giorikas]

I even gigged it direct and it was pretty good back then!!! For specific sounds...Maybe not the plexi style sounds. But damn good. The mesa studio preamp direct was as good, better than the triaxis.

[@dezionlion]

81giorikas the pleco style sounds are the whole reason you buy a marshall!

[@dezionlion]

Plexi

[@murphshall]

Mine never sounded this good either. The thing I didn't like about it was it couldn't get a decent Plexi tone out of it.

[@2550marshall]

I have had a JMP-1 on and off since they first came out. I think a lot of guys had them modded because they didn't know some of the secrets or how to use them correctly. Here are a few that I have realized over the years, BTW I always got complements on my tone when using one. Still have one and is still my go to for anything live. 1) Set the Output volume knob to only around 2-4, 8 Am to 10 AM. 2) Use the internal digitally controlled CH volumes to adjust the overall volume of the preamp and the Output for just minor volume tweaks. 3) Higher Ch volumes and lower gain settings work better. 4) OD2 and the bass shift are pretty much useless stick to OD1 for gain tones. 5) Although not a true fully tube preamp, the two tubes in the preamp do make a difference in tone. One tube does the clean CHs and the other the OD CHs. Experiment with different tubes for the best tone. I like a Mullard for the cleans and a JJ for the gain. 6) The power amp you use with the JMP-1 makes a BIG difference- I highly recommend a Marshall with EL34s. For more vintage tone use a 1987X, for more modern tones use a DSL. 7) Don't think this is a high gain preamp, clean to moderate gain levels is what this thing does the best. 7) One of the biggest secrets: Follow the JMP-1 with a BBE Sonic Maximizer with it's knobs set at about 1 O'clock. The BBE will pull down some of the honky mids and make this preamp a monster.

[@markuspieronczyk398]

Hey 2550marshall I use mine with an BBE Sonic Maximizer as well, my power amp is an Marshall Valvestate 120/120 Pro. Sounds very pleasant and 80ies to me. :-D Thanks for your advices, gonna try them out. :-) By the way - OD1 and a Tube Screamer sometimes can be fun too.

[@SuperWaxer]

2550marshall cool. Would you be willing to share your experiences on : facebook.com/themarshalljmp1/

[@robvoyles]

some good stuff except for the JJ tube, they suck in most amps, this one is no different, mullards are smoother no doubt but NOS Chinese tubes are what makes these pre amps sing and the Rocktron exciter/imager is a must.

[@JordyJayHomer]

Gee, I'd describe mine as very high gain. Maybe they're not all created equal

[@ChrisBlackTV]

I have a JMP-1 as well. I actually like the OD2 channel quite a lot. You can get some awesome sounds out of it, but only if you set it up right. It has way more gain than it should, so do not set it to more than 15. Otherwise it will sound like a wooly mammoth charging at you. Scoop out the mids (the sweet spot seems to be somewhere around 0 to 2), crank up the presence, and don't go overboard with treble. Also, I do not recommend using bass shift with OD2, it just doesn't sound right.

[@AngusClarkGTR]

That, the marshall 2x50 Watt power amp, a PCM70, and a 2x12 cab was my rig for all three years I spent touring with Kitaro (‘94-97). The whole “An Enchanted Evening” album and video were done with it. We got a Grammy nomination so I figure I got my money’s worth. Thanks for demo-ing it!

[@LeonTodd]

How did you like the Marshall power amp? I always wanted one to run with my JMP-1 but just used to use the fx return of a head which was a bit clunky live.

[@AngusClarkGTR]

Leon Todd I’d have to hear it again to tell you. It was never amazing. That’s the rig that couldn’t compete next to my singer’s hot rod deville and how I wound up being “a plexi guy”. It was part of a journey. It worked great on that gig. The cab was inside a tympani drum case, running stereo, with Sennheiser 421’s. We were on in ears - in ‘94!.

One of the best tones I ever pulled was this preamp into one side of the gold el34 dual mono block 50/50 poweramp. I was playing the palais in Melbourne (lovely old theatre) and I was in tone heaven all night. Standard 1960a cabinet and a les paul.

[@FuzzWoof]

I toured with two of these in a big fridge rack with the matching 50/50 power amps back in the 90's and absolutely loved them. Recorded direct with them all the time in the studio and was always pleased with the results. Pain in the butt to make quick adjustments on stage though! I'd love to grab another one and see how it sounds direct put it through a modern IR power amp/cab plugin.

[@FirestormAudio]

That tone at the beginning!

[@pops71]

Great work as usual. I had a bunch of MP-1’s over the years. I always thought the Marshall was cool, but all the guys I knew that had one were such Dbags about how they played Marshall that I never got one. I think I will hunt one down. Thanks again for reminding me how awesome the 80’s were, you Da man!

[@terryp9484]

Man sounds amazing - great playing .

[@patrickfouhy9102]

I used to tour with a JMP 1 and a Triaxis. I got pretty experimental with them, but eventually just used them one at time and would switch depending on my mood at the gig. The trick with the JMP is that it REALLY needs something like a tube screamer in front of it if you're going to use OD2 channels. Also, I found that the voicings of the 2:90 power amp really complimented the JMP nicely as well.

[@noworries12]

[@Hbguitars1]

I use two of these, wet/dry 2 - 1960B’s These preamps are amazing no matter what your playing.

[@tommygunrva]

That "honk" in the mids is the signature, and it is wonderful! That preamp was a goosed up digital version of the JMP head. That's why if you go: [ OD1 / Gain-15 / Bass-6 / Mid-2 / Hi-0 / Pres-2 ], you get "Back In Black-era" Angus Young. That mid-range honk is part of the original JMP SLP sound. The clean channel as well. While OD2 gets into more Lee Jackson/Jose Arrendondo-modded 2203 territory in regards to gain and low end. I've had a few of these in the studio over the years. They always sound spectacular. They are super hard to find though. If you ask certain folks at Marshall, they'll tell you Big Billy Gibbons bought them all from the warehouse when Marshall took them off the retail market. That could be urban legend though.

[@marcosdanielponce3285]

interesante aporte...!! gracias,, lo voy a setear de ese modo luego y probar con la LP. interesting contribution... Thanks, I'm going to set it that way later and try with the LP.

[@JohnSmith-ef2sx]

Dude you get your hands on the coolest shit. Love it glad I'm subscribed.

[@dimebagtribute]

What I love with those kind of gear (digital and modeling preamps) is that you can couple it with a good solid state power amp hooked to a 4x12" and you have a "portable" rig that can blast 300Wrms!

[@AnAmericanGuitarist]

I bought a JMP-1 new and used it for around 2 decades with a Marshall Dual Mono block 9200 power amp in the rack. The 9200 has 5881 power tubes. I always hoped for newer versions of the JMP-1 (Maybe a JMP-2?) because I wanted a little more gain out of it, but at loud gigs when the 9200 was bringing things up to a respectable volume the whole rig just fattened up nicely.

[@RavenMadd9]

thank you .....nice demo

[@tonykennedy8483]

Great tones and really enjoyed the nod to Def Leppard's White Lightning in the beginning, though y'know they started using the JMP during the touring for the following album - great vid

[@stankowalski4574]

I remember reading somewhere that the JMP-1 was basically analog solid state distortion, and that the tubes were included simply for marketing purposes. Don't know how accurate that is, but this JMP-1 sounds really good. Wish Marshall would re-issue this or even an updated version. Good tones.

[@liquidSpin]

I've ALWAYS wanted the Marshall JMP1!

[@EddyLenz]

Awesome intro! I was quite surprised by how good the JMP-1 sounds :D

[@blairwaller6200]

This has got to be the best sounding intro/tone/lick I have ever heard. I’m probably responsible for 61,338 of those views personally.

[@marcocivita3402]

Totally White Lightning-inspired the intro! Ahaha Great stuff Michael, I had a JMP-1 years ago and it was (still is) a great preamp.

[@bigdavedave9865]

Awesome stuff. The intro was like Def Leppard meets Giant 👌

[@marmaladecream2233]

Fun demo! I've been interested in these for a long time because of Billy Corgan's rig from the Mellon Collie era. I believe he ran through Mesa Strategy 500's with the deep switch on, which accounts for all the low end in that tone.

[@terryrichardson3054]

That sounds absolutely monsterous at the start of the video. I expected the JMP to sound good, but not THAT good! wow. Great video.

[@90sPunkRockCovers]

Huge fan of the JMP-1. I wanted it one badly in the late 90s but never got into the whole rack mount set up. I guess its never too late to start. Sounds great, cheers man.

[@SuperWaxer]

90s Punk Rock Covers I have been hearing those questions more often. Check out facebook.com/themarshalljmp1/

[@jcoriha]

The JMP1 direct was also a lot of the NIN tones.

[@santibanks]

That is what I thought as well but I never got these signature NIN guitar tones from my JMP1 in direct mode. I mean it gets you sorta there but in the way that any distortion/fuzz recorded directly will get you there. He recorded a lot direct via the JMP and also his Zoom 9030 but those very nasty signature guitar sounds (Mr Selfdestruct, Heresy, I don't want this, Eraser, No you don't) are all guitar recordings f*cked up with Metasynth. I think the JMP1 is probably most used "raw" on the Broken EP. And for more conventional distorted guitar rhythms/leads on Downward Spiral.

[@tonlarj37]

I used to have one of those, and the ADA. Nice video, man!

[@damianval4626]

I had the complete package Jmp1,jfx1,dual mono block per amp and 1963a cab👌🏻 The jfx had great delays and reverbs

[@antilaw9911]

In the mid 90"s i had this whole setup found at twin town guitars in Mpls. JMP1-JFX1-9200 power amp. Same as Dave Murray from maiden. Best gear i ever had snd got rid of it because i thought JCM800 head looked cooler. Went all downhill from there. Not enough gain so kept going through all the different amps out there. Lesson learned!! Keep your stuff!!

[@jm71681]

I wanted one of these SO BADLY when I first started playing and really? Nothing has changed. I still want one. As well as that Soldano pre, and ADA MP1 you have there as well xD

[@sheatanner9935]

I have a stock JMP-1, it has it's little idiosyncrasies but all in all, it's an awesome little workhorse for me. Even with my Hughe and Kettner Trilogy, I still gravitate to the JMP. I suggest you get one if you can. I plan on getting mine modded by the folks over at Voodoo... as soon as I have a spare grand (sigh). I love mine though and the tone is still killer for being almost 30 years old.

[@ExpatZ266]

I had an X88R for a bit, freakin awsome but NOT $2000 more awesome than the mucho maligned SP-77, give that a go if you don't need the over the top drive from the X88R. Waaaay more affordable and for the price of the X88R you can buy 1 for studio, 1 for live and a backup.

[@robertritzenthaler6618]

My band just recorded an EP using a JMP-1. Love this preamp.

[@jfgamuz]

Definitivamente el sonido marshall es el soundtrack de nuestras vidas....!!! 👍🏻👍🏻👍🏻

[@JulianMerghart]

A lot of rookies are just finding out about rack preamps. While they do have their place - things can start to get very expensive. I am convinced that feedback (the magic electrical interference that defines rock and roll) can be compromised when the preamp and power amp live in separate spaces. Of course, it still happens, but a Marshall head has one specific place where everything comes together and I can appreciate that. I am one the fence with preamps and I have a bunch of them. For touring? Always a good thing. For direct recording they pretty much rule too. But I feel like people are trying to increase the value of their preamps with this new preamp KZbin revolution.

[@baronvonchickenpants6564]

Mine never sounded like this!! But I used mine live with the 9100 Poweramp and a 4x 12, much preferred the TSL I sold it for

[@huginstarkstrom]

I've been using that amp ever since it came out and got no inclination of changing it. I use a H&K 2x50 power stage and a TC electronics G-system. Changing sounds on the G-system also changes sounds on the JMP (via Midi obviously). This means that with one footswitch I can change effects and channel at the same time - and that for 128 channels. The H&K had to change tubes a few times, the Marshall still has the original ones.

[@satch4u3]

Sounds great. Would love to hear you demo the synergy stuff.

[@joepeeres5335]

I thought you did a great job!! Also when you demo it like this it shows how quickly you can change sounds and setting, I thought it sounded pretty cool overall and like you said.. 3 4 hundred bucks.... what more do you want...better than a pedal and more versatile...as far as I see it Keep up the awesome demos!! Very entertaining and informative!!

I have one of these. Modded by Trace at a VooDoo amps. There are things it does really well, but there are things it does poorly. Some really good clean tones on Clean 1 channel. Great crunch on OD 1, but only at higher gain tones. Don’t look for warmth or smooth low gain.

[@moimeme7839]

[@irmasil3]

I use a Triaxis and an ADA MP1 3TM for high gain sounds. I use my JMP-1 for pure "Marshall" tones, OD1 makes a very good impression of a JMP45 or Plexi, which I always use with a DOD250 OD in front and I get the best "Yngwie" tone ever. That is the only way for me to get a very accurate early-era Yngwie tone, which basically is super clean and sounds overdriven rather than distorted, but has enough pick attack and sustain. The mid "honk" is actually quite useful to get this sound.

[@seamanjive]

I don’t know if anyone let you know yet, but you can buy replacement encoder knobs. They run around $60 or so. I just got replacement input/earphone nuts and bezels ,replacement volume knob, replacement power button for mine. The encoder works fine, thank god.

Good one, been wondering about this preamp for a while! It's my friend's dream amp and I wanted to hear what's up with it. It was better direct than with The power amp! But it actually does have really good sounds. Just a very poor interface. Marshall should totally rerelease this with like full default front face knobs and then buttons for different amp models like "JTM, Plexi, JCM". It would be a total kickass product. Also Dimebag played everywhere with shorts like yours, I think you can do a gear demo wearing them.
