Teach Me how to match power + Pre on rack systems. JMP1 COntent.

[WITH FULL DISTORTION]

Hi GUys
long time no post right?
Im thinking about getting a Marshall JMP-1 after hearing this awesome clip here https://www.youtube.com/watch?v=yqwtgJbtEJc
But im completely NOOB when it comes to RACK SYSTEMS
i know what it is but i dont know how to combine PRE with POWER , of different brands to get the best of both worlds: A Dense, thick and tight bass , mid bass, and a crunchy, grinding mids, with increased sustain and articulation on the high mids and highs. sorta singing highs tone.

Im getting this marshall JMP1 and i dont have a clue which power to get with it.
IM currently with a Fender evh 5150 III head 50w that i like, although its too bright for my tastes. and not enough crunchy.
im pairing it with a mesa 2x12 clone with 2 celestion G12H-75 Creambacks that i liked. BUt ill switch to a 4x12 and ill also pick two more celestion speakers, but ill think about which ones. V30 didnt work for me last time with the 5150.

SO, my thoughts are : SHould i get a Mesa 50/50 power to go with the Jmp-1? or should i get something else?
THanks in advance
JP

Run the preamp into the effects return of your EVH. You can thank me later for saving you a ton of money.:werd:

Yeah, i ve thought about it too... but the Evh Doesnt have a CLEAN channel. its already distorted. Q: (
thats the second reason i want to part ways with it.

I've played a JMP-1 through a Mesa 50/50, and it totally nailed Dave Mustaine's Cryptic Writings tone. Keep in mind that the JMP-1 doesn't have all that much gain as far as preamps go; your 5150iii easily has A LOT more gain. You'll also want some sort of effects processor like a Rocktron Intellifex or Alesis Quadraverb if you want simple, or something like the TC G-Major 2 or G-System if you want more complicated / powerful. Also if you've never played through a rack, it can feel a bit disconnected compared to the more immediate response of playing through a head.

As far as power amps go, Mesa and VHT/Fryette are the best regarded as far as hard rock and metal players go. All of Fryette's offerings are excellent with the 2150 and 2/90/2 being the deepest, tightest, and loudest. Mesa has built A LOT of different power amps over the years and some are better than others. The Strategy 400/500 and Coliseum 300 amps (150-200W per side) are rare, heavy, expensive, and far too powerful for any venue smaller than a stadium. The next tier of amps include the Simul 295, Switch Track 395, Simul 2:90, and Recto 2:100. My personal favorite is the 395 as it had the most amp-like feel, particularly with EL-34s in the class A sockets. The 295 is considered to be up there with the VHT 2150 in terms of legendary power amps. I don't personally care for the 2:90 and 2:100 as they didn't sound that great in my experience, no did the newer 2:50. The older 50/50 you asked about sounded better than the new 2:50, 2:90, & 2:100, though not as good as the 295/395. The Marshall 9100/9200 and EL-34 power amps are decent, but not as good as Mesa /Fryette.

the Evh Doesnt have a CLEAN channel. its already distorted.

This is largely a result of its pre-amp stages.

You are supposed to do as Edward does. Roll your guitar volume control down to between 2 and 3. The amp should clean up with no drop in sound pressure level.

JMP-1 Owner here.

If you're looking to try one out, get the JMP-1 first and run it through the 5150 (you will run it into the effects return, clean/ dirty channel don't matter here your only using the power section) so you can see if you like what the JMP-1 is doing before going to spend on a power amp. Power amps do make a big difference, but if you're not even close with this, then changing power amps isn't going to make it a totally different amp if you know what I mean. The JMP-1 really is the main component.

Personally I use a Peavey Classic 60/60 power amp (6L6s). Got it nice and cheap and it has been super reliable since day 1. Love the tone. It's really best to experiement. If you have friends with other amps you can run it though, maybe you can get an idea for what kind of power tubes you like with it.

You run your guitar into the input of the JMP and the output of the JMP to the fx return on the EVH which totally bypasses the preamp of the EVH. Don't run into the front of the EVH and try to patch the JMP in the loop, that will sound like crap.

As far as power amps go, a lot depends on your budget and if you really need tubes. The ISP Stealth is a great little power amp. The old Tubeworks MosValves sound great too and can be picked up pretty cheap these days, the best sounding rig I ever used was a Kasha Rockmod II preamp into a Rocktron Replifex and/or Intellifex then through a MosValve power amp in stereo through a couple of Avatar 2-12 cabs, sounded amazing IMHO.

Of course, the Mesa and Fryette amps are great if you have the $.

Guys... thank you for the awesome support
ill try it out with my 5150 and see what i like and dislike
then, ill see if i can find more amps to run it through the fx loop.
Q: )
my budget isnt great and i think ill try to try one of those ada preamps or a preamp designed for the axe fx that a friend of mine here has or had. ill see if i like it with tubes or transistors.
but i suspect that ill enjoy it better if it has tubes. i mean the power. the preamp may be hybrid. no problem. Q: )
Thanks once again guys
ANy soundclips?!

here's a soundclip of my JMP-1, carvin tube 100, and carvin legacy cab (v30s) with a guitar loaded with a lawrence L500L. Not a fancy recording but you get the idea.



If I went carvin again, I'd get the newer silver TS100 one (on sale right now for $595: http://carvinaudio.com/products/ts100) so that it'd be under warranty.

I always wanted to try a rocktron velocity to see if it'd still sound similar.

People say the jmp-1 doesn't have enough gain, but for my style it has plenty. Some settings are actually "too heavy" for me. I use Preset #7 (Midlands I guess they call it) with the mids dialed back a tick or two and the gain up a tick or two.

The Peavey Classic 60/60 is an amazing power amp for the budget; I concentrated on Mesa in my post because that's what the OP asked about. If I were building a JMP-1 rack system these days, my #1 choice for power amp would be a Mesa 395 if it were at all feasible. Failing that, the older Mesa 50/50 sounds amazing without breaking the bank. If budget were a primary concern, Peavey 60/60 all the way.

I've played a Rocktron velocity and it sounded pretty good for solid state. It wouldn't be my first choice as a power amp, but I'd absolutely go that route if I needed a backup. I did mention the JMP-1 not having all that much gain, but I agree that it has enough to get the job done. The Megadeth tone I mentioned was on OD2 with the gain in the 16-18 range (out of 20). That's quite a bit higher than the 6.5-7 (out of 10) that I needed to reach similar levels on my Soldano SP-77.
