JMP-1 and rack questions

AC_inacornfield · 11-15-2009, 09:32 PM

I'm wondering if someone can answer a few questions for me. I'm thinking about going to a rack setup. I'm getting tired of trying to hit 3 or 4 buttons to go from clean to dirty sounds. What makes me nervous is I'm unsure of how they work. I get that a power amp and a preamp is needed. But what I really want to know is if I purchase a power amp preamp and a effects processor and some sort of pedal board. Can they all be programed to work together in midi? I would love to hit one button to go from clean with chorus and maybe a little delay, straight into a OD channel. Is this to much to ask? Can it be done? Also how does the JMP-1 sound? Any good advice would be great thanks again!

Yes, it can be done. That is exactly why I got a JMP-1, pwr amp, and processor...so I could press one button to switch a bunch of things. A midi controlled processor with pedalboard will switch the JMP-1 settings simultaneously with the effect settings. I basically had three "patches"...

- clean setting on the JMP-1, whatever eq settings, reverb, delay, chorus on the processor.
- rhythm setting, different eq, less reverb, no delay, no chorus.
- lead setting with higher gain and volume, some reverb, more delay.

Switching multiple things with one button is just one of the advantages, the other advantage is that you can have many patches with the same effects but with different parameter settings..for example louder delay, longer delay, flanger, chorus, phaser, eq's...etc. With individual pedals, you can't make setting changes on the fly...what do you do if you want a short delay, and a long delay? medium gain, low gain, and high gain?

If you get a stereo power amp and you have two cabs, you can get the most out of stereo effects.

I don't use it much lately, but here's an old pic of my rack rig. Not shown in the pic, to the right, is another cab for stereo separation...sounds pretty cool when you hit the stereo chorus.

The JMP-1 has 100 programmable patches, and most processors have at least that many or more. This means that you can effectively have as many different sounds as you need at your feet, without adjusting any settings on the fly.

Until I changed to all-in-1 preamp/effects processors like my Fractal AX-FX Ultra and Digitech GSP1101 in my gigging racks I rocked a JMP-1 and powered it with a 9200 Dual MonoBloc power amp and loved it. I used an old Digitech DSP128 Plus for my effects with my JMP-1,but alot of people use the TC Electronic GMajor or something like that. I run into either one 1960 in stereo, 2 1960s in mono, or a couple of Rocktron 1x12 cabs.

Check out a Liquid Foot Pro or Liquid Foot Jr midi controller if you go JMP-1/power amp/effects processor.

The power amp itself has no "MIDI'able" settings. However, a MIDI compatible effects processor in the FX loop of the JMP-1 is a killer setup. The most common config would be the JMP-1 and the TC Electronic G-Major. The FX loop is a parallel one, so you would set the processor 100% wet and use the FX parameter on the JMP-1 to set the wet/dry blend.

This was my rig for a couple of years until it got ripped off. Would I buy another? If I were in the hi-gain relm of things again, I'd jump at the chance and wouldn't think twice about it!

I just went from using a head with pedals to a JMP-1 rack rig with my band as I had the same issues; wanted a wide array of sounds without a lot of hassle switching them. I'm using a JMP-1 into a Valvestate 8008 stereo power amp and isolation cab, with an old Art reverb (non-midi) in the effects loop. I'm very pleased with it and my band is as well.

I don't think the distortion tones of this rig is as good as my other rig (Vintage Modern into 4X12 cab) but it works well enough to do the job. The only thing to remember about the JMP-1 is that it does not at all try to sound like anything but a Marshall. If you are looking for Fender overdrive tones, they aren't in there. It's kind of like the most versatile Marshall you could want to find. It does the heavy overdrive Marshall tone very well. Some folks say the clean tones are bad, but I really like them.

One other thing about the JMP-1; the tone controls are VERY sensitive, to the point one click on the knob will make a bigger change sometimes than you want. You have a lot of control there, so be patient in setting your tones and change the controls in small increments.

It sounds like the JMP-1 will do what you are looking for. The JMP-1 has been designed to be the central part of a midi guitar rig, it has several advanced midi capabilities such as being able to trigger selected midi patches from a specific preset. In other words you select the patch on the JMP-1 with your footswitch, and the patch on the JMP-1 will select a differently numbered patch on your effects processor to go with it. This is very helpful in a midi rig.

jcmjmp · 11-16-2009, 09:22 AM

I'd like to add that the Rocktron midi mate is a great tool to control your rig because you can set it up so that one row selects presets on your gear and the other row can select individual effects so that you can, for example, turn on/off the phaser or a clean boost for solos using the same preset on the JMP-1 and Effects Unit (I use a G-Major).

You're referring to "MIDI Mapping". The only thing I do not like about the JMP-1's MIDI mapping facility was that it didn't seem to be seamless...i.e. there was a SLIGHT delay in the switching of the effects patches when mapping effect program changes through the JMP-1.

When I had mine, I used the Behringer FCB1010 MIDI controller with it. The ONLY piece of Behringer gear I've ever liked, the FCB1010 has 5 individual MIDI program changers in it that I would assign to different MIDI channels. I then would assign my JMP-1 to MIDI channel 1, the G-Major to MIDI channel 2, and my Digitech Whammy to MIDI channel 3. Then if I wanted one preset to switch the 3 different devices to 3 different patches, I would program each of the program changers to send the appropriate program change message on the channel that corresponded with the device that was on the MIDI channel of that program changer. Everything was mapped through the controller itself rather than each individual device. With the FCB1010, the hookup differs in that instead of running from the MIDI Out of the preceding device to the MIDI In of the proceeding device, you instead hook from the MIDI Thru of the preceding device to the MIDI In of the proceeding device. This way, all MIDI messages coming from the controller are available to all devices, but each device will only respond to messages sent on the MIDI channel that corresponds to the MIDI channel that each device is set to.

The Digitech GSP1101 processor with the Control2 pedalboard has that feature too.

Didn't know that - I'll have to look into it. Thx!

I just got the GSP1101/Control2 last week, and did a gig with it this weekend....so far it's pretty good, but I have some complaints that I suppose I can live with. I have an older Digitech GSP21 unit (in that pic I posted) that had that feature also. Don't know if all Digitech stuff does it, but I know these two do.

I like that feature...so far I've never needed more than 5 patches available at the same time, and it's nice to be able to kick in/out individual effects.

I'll let you in on a little secret if you promise not to tell anyone. Since my Jubilee's preamp has been making alot of noise lately (hum), I used the GSP1101's preamp for the gig this weekend. The main reason I got the thing was my Lexicon failed, and they both have the preamp loop feature (4 cable method) where you can either use the internal preamp, or the external preamp of an amp head. So for the gig, I was only using the Jub's power section. The 1101's preamp isn't too bad, I didn't totally hate my tone. Of course I missed the Jub, but it got me through the gig without any issues.

all of the Digitech stuff i have owned are like that
as for the tap dance routine their are other ways around it. units like the Ground control.....the Lexicon mpxr1..the Roland fc200-300 and the Behringer FCB1010 all have at least 1 relay controlled switch just for channel changing
i got lucky and found a Peavey MidiPro that has 8 switches and 4 A/B loops
and at $50 brand new in the original packaging none the less
my current foot controller is a Digitech RP20. i had the Lexicon but sold it to buy more gear (Gas)

jcmjmp · 11-16-2009, 04:33 PM

The Rocktron is very straightforward - no tap dance to switch effects on/off.

midi masters out there please go to my midi help thread!

[Rant mode on]

I used the Lexicon MPX-R1 for 2 years, and I'm quite disappointed with it (I'm EXTREMELY disappointed with the MPX-G2 processor too, but that's a whole 'nuther story).
-Two of the buttons on my R1 stopped working
-it doesn't have the 5/10 patch mode thing like the Digitech
-the display is too small so it doesn't display the patch name and I don't like how it works for the tuner
-the top row of buttons are a pain to use without hitting the bottom buttons
-the expression pedal doesn't stay where you left it
-the buttons are kinda noisy when you press them
-It also requires a wall wart power supply.
Fortunately it can receive power through the 7 pin midi cable, but the big external power supply must be plugged into the processor, so it takes up space in the rack case. The Digitech Control2 gets power (and midi) through the 1101 via a standard $10 Ethernet style cable rather than a $30 7 pin midi cable.

I wanted so much for the Lexicon stuff to be great, but as much as it pains me, I can't rely on it. I now have the Digitech GSP1101 and Control2. It's true though about the relays in the R1, it can switch your amp channels (with a separate cable, obviously), but I don't need that feature.

I'm sorry Lexicon, you failed me, so now I have to use Digitech....but since Digitech now owns Lexicon, and the GSP1101 has Lexicon processors inside, at least it's heart is in the right place. It's probably a good marriage...Lexicon makes stuff that sounds great, and Digitech makes stuff that works.

Wow thank you to everyone who helped answer my question. I got alot from reading all of your post, and now I'm going to have to look into going with this setup. Does anyone know if Marshall still makes the 50/50 and 100/100 power amps? Or will I be searching ebay for a used one?

Looks like they do.

i was referring to regular pedals and amp channel pedals...no tap dance with the Digitech stuff either and pretty strait forward

@Adwex...great and very true rant...thats all mostly why i got rid of mine
i already had the RP20 and thought Hmmmm.....wish i would have had that thought when i first got the MidiPro

as far as the power issue i may mod my 2101 and RP20...they both have 5 pin midi connections and if my memory is correct midi only uses three so i may do the "Phantom power" idea so i can just use 1 midi cable and not 1 midi and 1 power

They still make an EL34 100/100 but they discontinued the 50/50 version.

I have the older 9200 Dual MonoBlocs that are 100/100, but they use 6L6s. Came stock with 5881s,or so a sticker on the front of the amp states,but mine all had 6L6s in them. I have 3 of them and gave about $500 average for them,all used on EBay and Craigslist. Great power amps. Pure clean power,wide headroom. And very hefty. I think they weigh about 60lbs or so. These monsters could drive 4 1960s easily. I'm running 2 side by side and usually have the power amp on about half throttle. Extremely loud. My bandmate plays thru a 100 watt head and I am usually drowning him out and have to turn down.
