Howdy eddyrox,
Have you tried the Ebay nightmare yet. That's how I picked up mine. About $500.00 with shipping. I then sent it to VooDoo to have them do the mod. Another $350 with shipping. Once it returned I wasnt so happy with her, but after some phone calls and emails to VooDoo she is incredible. The JMP-1 is still kind of a two trick pony. I have her set up to be like a 4 channel head. Clean, crunch and two solos. I got to tell ya, she rips heads. The mod warmed her up and took alot of the buzz out of it. Its still really noisey but Voodoo showed me how to get around that. My tone is pure Marshall. I run her through an EL34 100/100. (TC Elec. G-major/Dbx 266Xl comp/BBE 422A in series before the amp)

I like it so much that I took the chorus off of my rythmn patch. Straight up Marshall spank, no color, no modulation. Just good old Marshall bark. Pick attack is sharp and defined. She feeds back really smooth. She likes my Les Pauls better than the Ibanez's. The RG's are bright and twangy (typical strat type guitar tone)

So good luck on your quest. The JMP-1 is a great pre-amp. She's finicky, but once she's dialed in...

picked one up yesterday on eBay for about the same $. Would be interested in talking to you more about the Voodoo mod. I've heard it tightens up the low mid for gain and removes the SS/sterile tone from the cleans. Your thoughts?

thanks in advance,
mike

Kendall124 · 07-01-2008, 01:54 AM

Well, here's the thing. My ears are wasted. Yep, 20+ years of having 100 watt amps behind me have taken there toll. Now don't get me wrong, I still hear just fine but as to being able to pick out all of the slight variations in frequency? Nope. All I can tell you is before I shipped her to VooDoo it was really brittle sounding. I had purchased (2) EH12ax7's. I didn’t notice much difference. It came back from VooDoo with an EH12ax7 and a Groove Tube 12ax7 gold pin in her. I should have opened it up to see if I could tell what they did. They're kinda secretive about what it is they really do. Truthfully, I thought all they did was change the tubes because it was still really noisy when she came back. The guys at VooDoo told me to keep the patches volumes to no more than 15. Then keep the output knob at 9 o'clock. Anything above that brings on the noise. My clean tone is incredible. Beautiful bell tones. I'll share some of my settings with ya once yours arrives. Actually, I have a spreadsheet of EVEYONES patches that I could find on the internet. Some are great some are... um... some are ok. It all depends on the amp you're sending it through. I'm also finding out that volume has a lot to do with the tone. As with all Marshall's, she gets better the more you push her.
So that’s my two cents on VooDoo. It definitely came back a better, more controllable preamp. Would I recommend the mod? Yes.

Kendall, thank you very, very much for such an honest answer. In all of my internet forum "travels", you are the very first person to EVER admit to hearing changes and it's related effects. I've had several Cameron-modded Marshalls over the years, and I would swear that NONE of them are alike - all "Jose mods" (for better or for worse), with tones from full on VH1 to Mesa Boogie II C+, and all in JMP/JCM800 2203's. Part of this is Mark's ability to get huge variations from a relativity narrow tone spectrum, but the other is due to the way he's "hearing" stuff now vs 10 years ago.

I've owned 2 JMP-1's in the past, and have a really good idea of the buzzyness that you've referred to - especially at stage volume. I too "typically" dial down the preamp volume and let the pwr amp do the heavy lifting (and determining the amount of "cut"). Of course having a Marshall (Drake/Dagnall) OT/PT is going to really determine how much of that Marshall-like "cut" is there in the final mix. However, IF I get this kind of a "tone"- about 0:09 secs in - then I'll be a pretty "happy" camper

thanks again for the info, and I'm expecting the preamp to arrive on Friday of this week.

Best regards,
mike

I have a JMP-1 question. What footswitch do you use with the unit? I recently found one used at a music store for $350. I quickly grabbed it but don't have a footswitch to control it with and can't find the Marshall one anywhere. So what do you recommend?

Bryan, I've got one of these
http://www.rjmmusic.com/mastermind.php

But, I'm gonna update my rig, and get one of these
http://www.axess-electronics.com/sc/...r-p-16138.html

The whole MIDI-thing is like a vortex, you don't wanna get too close, or you're gonna get sucked in....well I've gotten too close lately!

I'm running a couple Diezel heads, along with the JMP-1, and powering the pre's through an EL34 100/100 mono bloc. My pedals and EFX are being controlled with an SS Switchblade GL.

Kendall124 · 07-02-2008, 11:46 PM

Howdy Bryan and welcome to the forum,
$350.00???? Smokin' deal. I'm using the stock footswitch that came with the JMP-1. Four channels, nothing fancy. I don't need anymore than that. Clean, crunch and two solo's. My JMP-1 talks to my TC Electronics G-Major via midi. Keep an eye out on ebay.

Eddyrox,
Thats one bad*ss setup. Bet the soundmen love you too. How 'bout some insight as to how you have it setup. Cabs?
Kendall

Bryan · 07-03-2008, 08:32 AM

Thanks for the welcome. I would love to use the Marshall footwitch but it didn't come with one. The only place I can find them is in the UK but they don't offer US shipping on their sites.

And yes I love the JMP-1. Man is it nice.

Hi Kendall, yes I have one of those schematic/flowcharts that the HugeRacksInc guys love sooo much!

(if I can dig that up). Seriously though, this set-up is for recording (can you imagine lugging that to the pubs and bars we play at???

). For gigs, I'm a Diezel Herbert with a couple pedals kinda guy. Cabs - PV5150.

Cheap and beat in. Basically a Marshall 1960 cab (G12-T75's) but with EVH's version of the celestion (PV Sheffield 1200's). For recording I'll grab my VHT frontloaded cab (EV12L's

) or my EVH412 (the new one with the EVH celestions - basically the 20W heritage spkrs with an EVH logo

)

Regarding the set-up, I'm definitely NOT a W/D/W kinda guy - too much to go wrong. I'm more of an Eric Johnson-style amp user - amps seeing loads and set to go when needed, or blended. The pedals are all in dedicated loops and can be on or blended as needed as well all courtesy of the SS Switchblade.

Adwex · 07-04-2008, 10:18 AM

I used a JMP-1 for years, still have it. The true power and flexibility of it is unleashed when you pair it with a MIDI controlled effect unit. Since the JMP-1 has no effects built in, you're probably gonna want reverb, delay, chorus, etc. Most rack effect processors have a MIDI pedalboard that's used to change patches, and a MIDI "out" that is used to send the same patch changes to the JMP-1, so both units switch together. This way, rather than having only 4 "sounds", you can have up to 100, and each sound can be a unique combination of preamp sounds and effects, with different settings. I prefer this arrangement to using a 4 channel footswitch with separate effect pedals for the following reasons:

-less cables.
-neater, and easier to setup
-no batteries or power supplies
-practically infinite number of different patch combinations, each can have unique settings.
-some processors have a built in tuner
-you could have a set of patches for each song, if different combinations of effect settings are required.

Don't be afraid of MIDI. Yes, it can get extremely complicated if you want to get into sequencing, and MIDI drums and other instruments, but using MIDI to switch patches is simple, and requires little to no knowledge. When you step on a button on the pedalboard, (let's say for your clean sound), a command is sent over the MIDI cable to the effect unit to switch to that particular patch. A cable is connected from the MIDI "out" or "thru" of the effect unit, to the MIDI "in" of the JMP-1. The same command is received by the JMP-1, so it also switches to the same patch number. Since both units switch to the same patch, you can control both units from the same pedalboard. This is the beauty, and simplicity of MIDI.

Would a JMP-1 Control a Digitech 1101 in the same way as it controls a G- Major?

Yes, but it works the opposite way...the Digitech will control the JMP-1, not the other way around.

Bryan · 07-05-2008, 10:57 PM

Cool. Can I use the JMP footswitch to control the two units or do I need another one?

Bryan · 07-16-2008, 10:12 AM

Anybody in the know can answer this for me???

I'm not 100% sure, but I don't think so. Unless the JMP-1 footswitch is MIDI, but I don't think it is.

Don't you have a MIDI pedalboard for the Digitech unit? If not, you should consider getting one because that's the best way to control both units.

Howdy Gang,
just moved and internet is finally up and running. Yes the JMP-1 foot controller will operate the two. My set-up has the footswitch into the JMP-1 then midi out to midi in on my G-Major. Works like a champ. However, The JMP-1's footswitch only offers 4 channels to control. No MIDI bank up/down features. Works for me cuz that's all I need. So if you need more than that I would find a midi footswitch.

Bryan · 07-16-2008, 10:15 PM

Awesome! That's the answer I needed.

I was going to keep the Digitech and use it with the JMP-1. But I decided to go with the G-Major as the JMP-1 has all the preamp tones I want. Keeping the Digitech for effects only and not using its preamp would be a little wasteful.

I'm glad the JMP-1 controller works because I just bought one on Craiglist. If I need more than 4 channels I'll probably just grab the Behringer footcontroller. But it's got such a huge footprint that I'd rather keep it simple if I can.

alerich · 07-17-2008, 04:54 PM

I used an ADA MPC midi pedal when I had a JMP-1/JFX-1 set. Worked great. Ran them both into a Marshall 20/20 EL84 power amp in to an old Marshall cabinet with Celestion G12H30's that I split into stereo. That rig rocked. I downsized last year to a Marshall Studio 15 since I don't gig anymore but that rack rig rocked.

graydane · 07-22-2008, 06:18 AM

Mike/Kendall, could either of you shoot me an attachment with the list of settings you have for the JMP-1. Just picked one up and got it plugge din last night for 30 min or so. Gonna dig it.

You're welcome my preamp brother. Just a little thing I did to waste some time one day. I searched all of the sites and just cut/pasted all the settings I found into a word doc. I also, as you can see, kept a record of who/where they came from. Some of them are pretty good.

BTW... how's that foot controller working?

Bryan · 07-25-2008, 04:45 PM

You know if that word doc with the settings is just laying around doing nothing.....

My inbox is kind of empty. Can you hook up a new JMP user too?
