Our Guitarist swears by this! - Most of our songs were recorded direct through this - The song "never the same" used ENTIRELY the speaker emulated out. In a full band mix it sounds GREAT!
mind you - this thing was made in the 1990s. So many of the features that are standard now, were far ahead of its time. It's still in my rack and the first choice for me.
i use to use one in the late 90's early 2000's and just recently went back to it - i'm extremely happy that i did - i forgot just how awesome these units are!
You’ve become my favorite gear reviewer. I afford all that amazing gear, vicariously through you, and you do a great job explaining everything. Great player too!
I really like the JMP-1. I love the interface. The treble and presence can overpower the bass, so go easy and dial it in at stage volume. Try adjusting eq only one number once your in your tonal ballpark.The cleans are very good with single coils and compress in subtle way with gain up. Also, I think the dirty sounds respond to the volume knob well. Stock ones sound pretty good in my opinion. To restore factory settings (18 is my fave), hold OD1 and CL1 with power off, then press the power button.
I have JMP-1, 9200 and JFX-1 in my home in Europe, however since I don't live in the Europe for many years the gear is unfortunately just laying there and I miss it. I also had ADA MP-1 which had burnt PCB which I managed to make work, but since it was not that much reliable I gave it away. I really liked MP-1 chorused cleans, instant 80s sound and with Ibanez RG it can give you that Petrucci Pull me under chorused cleans.
Hi Mr. Nielsen! Your videos and info are great !!! I got one of these and love it. Some considerations about the battery replacement inside the JMP-1 ? Or some mod about the way that it's battery is atached to PCB? I'm afraid to ruined my unit, in a not so faraway future... 😮. Cheers from Viamao City, Brazil.
I've got one of these with a dead battery, so it really doesn't work right just now. I'm getting so much out of neural dsp plugins right now that it isn't worth the pain in the ass to find a tech who wants to fix up a 25 year old gadget. It was sexy in it's day, running thru a Peavey tube power amp to an avatar 4x12 with g12t75's. Great video, glad to see people are still rocking the jmp-1!
I wish I read this when you posted it. A dead battery will eventually leak acid and destroy your mainboard, so unless you really don't care about the pre, rush to a local tech and have the battery replaced if it hasn't leaked already! It's a 15 bucks fix tops...
@@jobsgarage thanks for the heads up. Leakage really hadn't crossed my mind. The battery has been dead for quite a while now with no obvious issues. Powering up with the factory reset sequence leads to normal function every time.
I sold mine 10 years ago... Never regrets about it... I record direct direct with jmp1 some song and it was good. I don't really like it comparated to some valve head including jcm 800, 900 and 2000.
Get one used. Be prepared to have it fixed / checked. And then rock out. If you have a boost / distortion in front of it you can get as heavy as you like. Just saying.
I have a JMP-1. It is basically a distortion pedal in a rack, none of the distortion is 'tube' it's diode based. That may be an issue, maybe not. The clean channel is actually all tube and is basically a blackface fender circuit. You'd be better off selling a jmp-1 and buying a better pre than paying for a Voodoo mod, unless you love the midi and the switching.
Not exactly right, both channels use one tube each. Tube swapping can make quite a difference. I have used a JMP-1 for at least 20 years. I have never felt the need to get it modded. Just follow the JMP-1 with a BBE and then into a DSL FX return or one of Marshall's EL34 power amps. All the other guitar players that hear my rig say the same thing, "dam that sounds good, what are you using?"
@@2550marshall the distortion channel use one tube stage and a cathode follower, essentially one tube stage. As at least 3 tube stages are needed for a distorted tone this is just for show...the distortion is generated by a bridge rectifier, in the same manner to a fuzz pedal. It isn't a 'tube' pre, it's described as a hybrid. I happen to build tube amps, so electronics is my thing! I'm sure changing tubes does affect the sound, if you like the sound that's all that matters.
Hey man. New to your channel and not really a 80s Rock guy but really enjoying your videos. Would’ve automatically bypassed this given its association with 80s and 90s rock but will deffo check it out now. Thanks!
1970s and 1980s were the golden age of Rock and Metal though. Everything went very stale and predictable in the 90s onwards, save for a few players and bands here and there.
I wanted a Marshall JMP and the Mesa TriAxis, but I bought the Peavey Rockmaster. When the Rockmaster died I got an ENGL e530. Last year I got the Synergy Syn1 and own the SLO, HBE, and the ENGL Savage modules. What do you think of the Synergy stuff?
I have a wall of amps here in Nashville along with preamps. The JMP-1 is by far the best sounding. There’s been a lot of money made from recordings and live venues with a JMP-1. Lol HELLO
That explains it.I am amazed how speaker emulated output sounds considering cab emulation is probably analog and it's hard to make it realistic in analog domain.Thanks for the info.
01:59 I used the exact same OD1 settings for this video, used the simulated cab out, exactly like here, and it sounded like.....weak sh#t, lol....nothing like this (trying both my LP guitar and humbucker bridge pickup on my Suhr guitar). I used an RME Fireface 802 to send the sound to my PC. Methinks there's something else going on here.
Hello. I'm very sorry for the stupid question.. Let's say I have 3 devices: JMP1, stereo amplifier, SV212. Through what inputs and outputs should this chain be connected? I'm confused.. Sorry again and thank you very much!
Hey man, for just home recording do you really need a poweramp or just straight from jmp1 to audio interface would be enough? My point is, do i really need a poweramp if I were to use IR for home recording? thanks!
My master/main out is waay quieter than the emulated out, also the pad switch (-4/-20db) does not seem to do anything. Might the pad just be stuck internally in the -20 setting? The physical switch works normal though.
Some help! Can I connect a effect rack to the JMP1? I have a Line 6 HD pro x, but I’m not sure how to hook up everything with the JMP, or which goes first in the chain from guitar to the amp.
Hey Michael, I have all the plugins you used to process the sound + I'm using the Nembrini JMP-1 Plugin for raw guitar tone. The screenshots you're showing of the delay and recerbs... are those the exact settings you used to get that sound??? I ask because I followed the settings to a T and my delays/verbs are no where near the sound on here. Love this tone and really want to dial it in and save it to my work flow. Love your channel my dude...
One of my coworkers has this, and I was gonna borrow it. But then I realized I had a Marshall Shredmaster that kinda does the thing pretty well. I ran it into the PRS Dallas plugin with a delay pedal. It was outstanding
Quick question for people using it. When I change patch I get 10-15ms of almost no sound. I checked with a sound editor and there is a kind of “hole” in the signal. Does it happen to you as well ? It is very annoying when entering a lead sound, cutes the energy of the first chord OR I have to anticipate the change 1/8th of a note before which is not ideal either. Same for you ?
The JMP-1 and the Digitech 2101 is a great match up for midi control. That's why I got it. 7 good sound's, clean reverb chorus,,, rhythm,,, flange rhythm,,, lead reverb delay,,, lead pitch shift delay,,, lead long delay ping pong,,, lead mid boost / volume boost run over EVERYONE channel.
Hi, master. Sorry the noob question: I have two JMP-1, one with CR2034 battery and another one with CR2032 battery, that I suppose that was the last JMP 1 version manufactured. I know that the battery is just to hold the memory. I have noticed that the one that have the CR2034 battery have a slight more lows/bass. The two JMP-1s have the same tubes (JJ Tesla) So that's the noob question: Can the JMP-1s manufactured in differents versions and in differents years sounds different?
Leandro Carvalho yeah, they can. It’s possible that they changed some components as well. Sometimes those parts seem like they would be a big deal, but ultimately add up to a difference
Unfortunately, I had to give $550 for my JMP-1, so with the Voodoo’s mod it would make the price $1850 + shipping, 😫. That’s just too much for me. One of the biggest complaints with this preamp is is the base noise level, if you have a late version model, Marshall added some power input filtering caps to help with that. The others don’t like that it’s hard to get this on the edge of breakup and use your volume to roll off the gain. That “may” be possible if running the JMP-1 into a tube power amp, YMMV.
I used one with the Marshall 9200 dual power amp for a very long time. I mostly used the highest gain setting and used my guitar volume knob to get a cleaner sound by rolling it back and it worked great for me, but if you're looking for a pristine clean sound then this method would still have a little too much dirt for you.. I made use of the midi for effects changes and EQ settings, but using this with a power amp adds a lot. At times I used the DI out for recording demos at home to a multi track cassette unit, but in a studio I always had the power amp, cab and a mic. You can also place an EQ between the JMP-1 and your power amp or place higher headroom delay and effects units there too. other effects worked better in the JMP-1 effects loop.
I have a video coming out that shows how I do it actually. Preamp, into the interface, then I use my IR. I created IR's through my favorite power amps like VHT, Mesa, HH, so the IR's have the Depth and Presence of the power amps baked into them. I like the difference... rather than using a regular clean cab IR. fb.watch/fbEaNjzMH-/
I don't have a JMP1, but a Boogie Quad. I haven't used it yet digitally because I always thought I needed to run a power amp with it. Is there a huge tonal difference between using preamp w/ a power amp going direct verse just the pre amp and an IR?
Why aren't the amp companies, namely Marshall, making tube preamps? For the home wanker/recording enthusiast who wants industry standard tube amp tone, it seems like a need. Or is it because a head like the JVM functions exactly like a preamp with emulated out? I think I just answered my own question. But a preamp only would be cheaper. JVM preamp, please.
just a f y i, if you have one, don t get it modded by voodoo amps, they screwed up one of my amps years ago so bad, i had to get it fixed by someone else, had this unit years ago, they sound pretty good with no mods alone, thnx mike
I owned mp1 and jmp1. I sold ada mp1 for the Marshall jmp1. I remember that was more aggressive and open sounding than mp1.. I sold jmp1 too some years ago
👍🇺🇸❤NOTHING BEATS.......USING A POWER AMP WITH 412 CABS BEING MIKED WITH A SHURE 57..........PERIOD . I use the jmp-1 in the most interesting & unique way....using a series of pedals in the front input & a effects processor in the loop........& no one on this planet has a better set up.....its all tweeked & tricked out......using long guitar & power cable runs & variac's (set at different voltages)......most pedals are on....so it's well buffered.....lots of sag & harmonics.....best distortion sound & feel I ever experienced.......I'm a genius.....it only took 25 years (so many fuck ups & nervous breakdowns)......I'm too selfish to share my complete set-up & secrets........goodluck & ❤GOD❤ bless all 😁
I can tell one thing, I removed the tube on the drive chanell, bypassed the pins with a wire and I still had sound and distortion. The tube is only there to beef up the sound!
I’ve thought about selling it before, but every time I plug it in, I end up having a really good time playing it. So, solid state or not, I’m gonna keep it.
Michael Nielsen surprised time see how the prices seem to have gone up quite a bit. I recall there was a time when these were all over the place for sale. I blame you 😁
@@georgebarry3153 Depending on who you talk to there is a variety of opinions as to how much the tubes add to the distortion channel. Some say it's a mixture of diode and tube, others have said it's all diode. In the end it sounds like a Marshall so like Michael said most who have it just keep it as is or get the Voodoo mod.
@@Cpt_Adama I owned it..and although it was a tad limited in its tones I liked it alot. But it seems Micheal is unsure wether its SS or tube. Its tube..and if memory serves they are running at 400v.
There's a famous Swedish amp mod guy named Tommy Folkesson and his slogan is "This amp has got a new heart!" His JMP-1 mod costs 3400 SEK (about 333 USD) and sounds AMAZING! On his website he explains what the mod is and what it does. It's in Swedish, but you can google translate it fairly accurate.
@@MrGul that sounds awesome. I’ve seen a few vids of Marshall heads he modded and they sound amazing. Does he let people in the US send JMP-1’s in for the mod?
@@jakedibiase7404 I actually don't know for sure if he does, but I'm willing to bet that he does if you pay for the shipping costs. Another possibility could be to have it done with a Swedish acquaintance/middle-man, should Tommy for some reason refuse international shipping.

I haven't had to deal with the battery issue yet. I'd check with VoodooAmps Mods (they do a lot of JMP-1 mods) or a tech on that.
Hi thanks Michael thanks a Lot for another Video on this great unit ;-) love your Videos. Cheers

working on it now
Hey Michael, I have all the plugins you used to process the sound + I'm using the Nembrini JMP-1 Plugin for raw guitar tone.

Love this tone and really want to dial it in and save it to my work flow.

For recording direct out of the speaker emulator into an interface, what cord is used? A speaker cable, a TRS cable, instrument cable?
Any ol' instrument cable will work fine.
@@BigHairyGuitars Thank you!!

It is very annoying when entering a lead sound, cutes the energy of the first chord OR I have to anticipate the change 1/8th of a note before which is not ideal either. Same for you ?
Nice! Maybe an ADA MP1 and DSP 128 sometime?
The JMP-1 and the Digitech 2101 is a great match up for midi control. That's why I got it. 7 good sound's, clean reverb chorus,,, rhythm,,, flange rhythm,,, lead reverb delay,,, lead pitch shift delay,,, lead long delay ping pong,,, lead mid boost / volume boost run over EVERYONE channel.
Hi, master. Sorry the noob question:

@@BigHairyGuitars Maybe I missed something in your video..but its a tube pre-amp. 12ax7s..I think.
@@georgebarry3153 Depending on who you talk to there is a variety of opinions as to how much the tubes add to the distortion channel. Some say it's a mixture of diode and tube, others have said it's all diode. In the end it sounds like a Marshall so like Michael said most who have it just keep it as is or get the Voodoo mod.
@@Cpt_Adama I owned it..and although it was a tad limited in its tones I liked it alot. But it seems Micheal is unsure wether its SS or tube. Its tube..and if memory serves they are running at 400v.
That Voodo mod isn't worth crap. I know a few how have it . All said not worth it.
Too much hum and noise on that thing. Get under stage lights and that thing is a mess.
The Voodoo JMP-1 mod has to be one of the most overpriced mods ever.
I agree and I have never seen a wie by side comparison… we are “assuming” it improves it.
There's a famous Swedish amp mod guy named Tommy Folkesson and his slogan is "This amp has got a new heart!" His JMP-1 mod costs 3400 SEK (about 333 USD) and sounds AMAZING! On his website he explains what the mod is and what it does. It's in Swedish, but you can google translate it fairly accurate.
@@MrGul that sounds awesome. I’ve seen a few vids of Marshall heads he modded and they sound amazing. Does he let people in the US send JMP-1’s in for the mod?
@@jakedibiase7404 I actually don't know for sure if he does, but I'm willing to bet that he does if you pay for the shipping costs. Another possibility could be to have it done with a Swedish acquaintance/middle-man, should Tommy for some reason refuse international shipping.
Horrible crunch tones
