- Prampli lamps (2 lamps).

- 4 channels: clean and 2 OD 2.

- No effect.

- I AIM that the volume of a JMP is controllable via an expression pedals. Nothing really mchant, but am forced to go through my multi-effects to play with the volume ...

UTILIZATION

- The JMP is a MODEL of a select intuitiva The argument is that you want to change, turn the knob data, there has been ...

- It's very easy to get a good sound, custom settings are really their rle, none of the to look pretty.

- The manual is very nice, he explains simply, but as I said dj, the JMP is a pilot very easy.

- The configuration of the southern part is of the same caliber as the rest, trs intuitive and efficient.

SOUNDS

- It is any type of music as long as you love the sound Marshall JMP 1 is because of Marshall, that's it. It is ideal that I like to play.

- For my config, see photo on my profile and Schematic.

- Am may be an alien, but I like the clean sound of a JMP
Otherwise it is the Marshall in the best sense, I will not explain what else do a lot better than me.

- There are a few blows on the OD2 channel that is sometimes Gnant ... with a small noise gate, it quickly rgl ... Apparently, it's pretty normal and only appears on the ca OD 2 (nothing on the other channels), not enough to make me doubt my choice.

OVERALL OPINION

- Rvait I, I, am happy ...

- I particulirement its ease of use, and sound gnral.

- It's the only pramp I tried I did that-l ...

- Purchased in OCCAZ Obviously 'in very good state.

- I would do this choice without a doubt.

Programmable preamp but everything is already explained in previous reviews!
As a rule the 4 basic sounds are excellent, the texture of the guitars totally respected and the settings are identical to those of any Marshall head .. The effects loop is mixable in its direct (12 is in series ).
The connection is sufficient that we can integrate easily into any system and outputs L / R emulating a Marshall stack are very realistic very useful!!

UTILIZATION

Simple setup really made for musicians .. We can change any parameter in full concert!
If you like the sound Marshall lamp, no problem getting a sound regardless of the channel .. Besides the presets have already been exploited or may be the basis ...
The manual is in English, so ....

SOUNDS

I use it in conjunction with the multi-purpose JFX1 inserted into the effects loop with just my Start + + rotovibe wha-wha at the entrance to the preamp ... and the fact that especially for the type of things standart blues quite heavy!! Good for the big metal it looks possible!!
I just changed the two lamps for a gain a little cleaner when I boost the input of JMP1 (integrated EMG afterburner in the stratum), but no other changes!
I love all the sounds clearer than saturated with or without the addition of JFX1 ...

OVERALL OPINION

I bought it at its output (in 91!) And then sold with the rest of the rack (JMP1 jfx1 9200 + + + hf tuner rack tu50 Nady hush + stereo) to return to something + rock 'roll (jtm45. .. I came back to the configuration JMP1 + jfx1 and frankly, I do not regret it and measures the height bullshit 13 years ago !!!!!!( already explained in my opinion JFX1) .. .
I bought everything in time so the price / quality ratio is excellent!! But be careful in this kind of buying the stuff is brand new pes or warranties and it is always possible to come across problems not mentioned by the seller !!!!!
In fact the choice I had done long ago!!

Tube preamp (12AX7 two, one for the Clean (V1), one for the saturation (V2). Please note that the saturation of the preamp is a saturation diode, lights are just there to color the sound (but we feel is a difference between different brands of lamps). For my part I stuck him in a Electroharmonix V2, and Marshall lying in my stock for the clean.

It is noon, 4 channels (2 clean, 2 OD), effects loop ...

A comprehensive pre-amp.

UTILIZATION

Not need a tray 5 for use. You choose your channel, the gain, the EQ is recorded and shoo!

The same applies to the South, we choose the channel and it's good.

Of gear designed for guitarists what! ^ ^

SOUNDS

Well, well, should be expected, it sounds Marshall! (Well, that's not a surprise).

So we like or not like it! Personally, I found it amazing that little machine! The clean sound is round and warm, not slamming the Fender, but fulfills its role.

The OD1 channel provides good friendly small OD for rhythm. AC / DC to the Foo Fighters

The OD2 channel has an extra headroom and a slight compression, which provides some nice sounds leads.

I used a Fender Lonestar US (Start HSS), and it was perfect for the great big rock US 80/90 's, with the Marshall and more biting.

Be careful to choose the Poweramp with this preamp. It gives its maximum with a good tube Poweramp (VHT 2502). It is a little soft knee with a Classic 50/50. I have not tested one in PA transos.

For those who want to sound Marshall JCM800 for their rack, go for it!

OVERALL OPINION

I have owned for 6 months, sold it to buy a Mesa Dual Caliber (which I think is playing in the same range of versatility, with the grain Mesa).

I changed it only move to a system pedals + head (tired of lugging the rack 35kg), but I admit that I regret it. I buy some new one later.

If you ever find the modified version (with change of the condos, and transistors with good tubes in it) go for it, it's really great stuff, and the amended version is more accurate and more musical.

Try it!

For specifications and review the original preamp, see below. On mine, I made the change, Dr. Boost (chgt condos on the audio line - sixty, ceramic films cons - chgts 15v regulators, amplifiers chgts Ops - 10 in all, the OPA2132 and 4132 to replace TL72 and 74). I changed the lamps by EH and other minor changes to control the breath. At the exit, not really spectacular ... But over time, there is greater precision in arpeggios, sweeps in saturated crunch or even a little push. This is especially the crunch and clean as we gain a better definition. Breath less, sounds a bit more "hifi", more modern (OP amps and condos are certainly something). Warning! That remains the Marshall! In any case the sound is changed. But it becomes more versatile and flexible as thinner and better defined. Consequently, you discover other facets of his guitar playing that lead to other types of uses that most of Marshall. Modif - gear and MO included - must revolve around the 250 €. I made ​​myself a small fifty € uro by drawing samples from the component manufacturers (TI, National Semiconductors, etc.).. Warning! This type of change is still an adventure that n is not within reach of a beginner. It is better to master the solder and the practice of desoldering braid and desoldering pumps. So think carefully before you start it!

SOUNDS

I do rock, variety, jazz, blues, hard ... A little of everything .. what I use it with a Ampulator ADA (I have no amp) on a active speaker Thomann PA302. I think it sends just fine!

Marshall has taken the biggest hold on the guitar amplifier world and completely pissed it down the drain. Sure people will still buy amps from them because they don't know what Marshall is now and they have some a strong hold on the market. Don't get me wrong I love Marshall the way Marshall used to sound. Now they just put out trash after trash. This preamp is no different. At least they discontinued this unit for now. I hope they are re configuring this thing because it sound like trash!

FEATURES:

* OD-1/Classic Overdrive channel - smoldering power will take you from a Super Lead Plexi's molten gold through to searing modern metal.

* OD-2/Modern Hi-Gain channel - tightly focused high gain drive by the truckload. Modern and aggressive, yet fluid and toneful, this stunning channel will give you all the distortion and sustain you'll ever need.

* Clean 1/Warm, Clean channel - for warm, full bodied chords, fat clean lead passages and jazz tones.

* Clean 2/Bright, Clean channel - has the glassy edge of a JTM45 and will give all of the bright, jangly tones you could wish for.

* Each channel includes the following programmable controls: Volume and Gain (0 to 20), Bass, Middle, Treble and presence (rainging from -6 to +6). A Bass Shift option re-shapes the low end character of each channel, too.

* Stereo Effect Loop is 100% programmable from 0 (fully dry) to 12 (full effects) and has level selection (-10dB or +4d) to match your effects processor.

* Each channel and parameter selection is made by pushing the relevant key and then adjusted by using the rotary Master Data control. Once you've dialed in a sound you want to savem simply press the Store Key twice. Recall is instant either from the front panel, via the optional Marshall 4 way footswitch (MPM4E), or via MIDI.

UTILIZATION

It does have tubes in it but who would have known. It sounds very sterile and fake. This is a beginners intro to preamps. I know that Janick from Iron Maiden uses this preamp but I'm not sure if he has it with anything else or if it is modified.

Anyway, you can control a host of presets with midi functionality. So it is quick to fire up a preset sound on the fly for gigging.

SOUNDS

The sound you get from this unit is sub par. Many users of Marshall over the years have said that this is Marshall's worst offering that they have ever created. There is nothing this thing can do to make it sound natural or anything like a JMP or a JCM 800. It is just bad!

OVERALL OPINION

It does have a Marshall British tone but it isn't something that you will enjoy playing will. You can find these units for around $500 or so used but save a few more bucks and get yourself a JCM 800 used. Slap a Boss SD-1 in front of it and you will get a tremendously better tone than you will ever get with this piece of tin.

I woulnd't recommend this preamp to anyone with the money that thy are going for. If you get it for free then maybe but save your self some time and effort and just move on past this. If you need decent preamp get an AD MP1 and get it modified for what you'd pay for this thing.

The Marshall JMP-1 is a valve based guitar preamp, offering a single space rack mountable unit for use with electric guitar. It’s great for the home or professional studio owner who doesn’t necessarily want to always set up an amplifier for recording guitars. The unit has two valve tubes (ECC83’s to be exact) inside of it, so you’re getting a pretty realistic sound for something that isn’t actually a traditional amplifier. It’s got ¼” jacks for input and headphones in the front. I’m not really sure what other types of connections it has since the one that we have at the studio where I work is racked up and hooked up to the patch bay already.


UTILIZATION

There’s a whole lot that can be done with the Marshall JMP-1, a lot of which I haven’t even tried to use it for. One of the smaller producer’s suites that we have at the studio complex where I work has one of these in there, and it’s definitely best suited in this sort of setting where you might not be able to use a real amplifier. It’s also great for beefing up tracks that you’ve already recorded with an amp. There are four basic channels in here – two overdrive channels and two clean channels, each with controls for presence, gain, volume, and bass, middle, and treble EQ control, as well as a Bass Shift control which messed with the low end of your signal a bit. Like any digital device, you can store and recall your settings quite easily. I haven’t seen the manual for this, but it would definitely be helpful to have if you can get your hands on it.


SOUNDS

The sound of the Marshall JMP-1 is about as close to a real amplifier sound as you’ll get outside of using a real amp. I’ll always try to get a real amplifier sound when possible, but have been using this here and there if I’m looking to beef up a pre-recorded sound or adding a new part if I’m not able to use the original amplifier I used. I love the versatility that you’re getting with the JMP-1, as it gives you more options than you could get with a traditional amp, and the real valve tubes give it a realistic sound, which isn’t something you can say for most of the units out there like this…


OVERALL OPINION

If you find yourself looking for a device to record guitar directly into your DAW, but don’t want to compromise too much in realistic sound quality, the Marshall JMP-1 is the perfect place to start. I haven’t seen too many other units like this one out there that offer a realistic sound in such a compact box with this amount of flexibility. It’s still not a replacement for a real amplifier, but it’s about as close you’re going to come…
