All user reviews of 4/5 for the Marshall 2203 JMP Master Volume Lead [1975-1981]

I would be short I do not have this amp is that of my roommate ... ^^
I know this is a 100W lamps there are two output levels to play casually in his room (even if I concde you is more for the sc only)
the settings are all that is becoming ordinare in MATIRE amp Lamps of age even if my taste the response of the EQ is pretty weak ... it says it is a Marshall ... but it has the mouth and believe me, he yells !!!

USE

The config is simple AC is plug & play and tan better! the sound is rock and another recess typ derivs not asking too much disto.Cela said, the one I tried did not go out as much distortion as the lamps rather rotten, we must say! after changing these bulbs con I ask a ressayage !!!!! we still even sound that can not Avoie on a Marshall worthy of the name, and that, it is magic !dropoff window

SONORITS

I play ACDC galore and a little more alternative rock or punk bcp but I like this sound and it should not hurt my type of music (coupled to a distortion pedal or metal ca lot clears) ! The sound is all the same rather garish and too shrill at times but it's even pretty cool

NOTICE GLOBAL

What I like least ... the pirx ... ^^ what I like most is the charism can possder what kind of amp there is one thing to say it's tough we not care about us! I know it's amp is not me but I think the new home sries Marshall polivalentes be more and better finished (I speak from a point view gadgets and appearance)

I purchased this amplifier used at Rebel Music in Oxford, MS. I had a 100 watt solid state Yamaha and wanted a tube amp. I got lucky and found this amp while looking at Traynors. It is probably from the mid to late seventies and has high/low inputs and a master volume control.

The tone, even though it does not have many features, the one thing this amp has that many new production amps do not have is great tone. If you put rat distortion in front of it you have Angus and Slash at your disposal. I only use the low channel because it is even loud enough to go unmiked at small clubs. The one thing that really helped this amp are the tubes. I have installed all Electro-Harmonix tubes and it makes a huge difference from the sovteks that were in there. This amp is a great find and if you see one, get it.

There is only two things wrong with this amp, the weight and the volume. Every good tube amp worth its salt is heavy so I can't really complain, but it is a pain to get it on stage. This amp is also intensely loud. the high input can get the cops at your house in less that 5 minutes. Even though the volume is good, it still can be a bit excessive.

It is an old Marshall, I have dropped it a couple of times after a long night and it does just fine. Except for a speaker wire becoming unattached, there has been no problems with this amp.

These are great amps and I like the combo because it involves less to lug around. The sound is great and it only cost me $400 and maybe about an extra $200 to undo some sloppy mods and to get it fitted and rebiase with some new tubes. I highly recommend these amps.

The Marshall JMP was the go-to amp if you were a rock or metal musician in the seventies and early eighties. Everyone from Thin Lizzy to Iron Maiden used them and the picture of a wall of Marshalls sitting behind an arena stage is something every aspiring rocker dreams of. This firebreather used EL34s in the power section to deliver 100 watts of British crunch. It is a single channel amp with standard bass, middle, treble, presence, and dual volume controls. After 1975 these amps were changed to the gain and master volume setup to appease the players who needed that distorted tone but couldn't dime a 100 watt head. There's no reverb or effects loop on this amp unless it is modified.

UTILIZATION

These amps sound killer for classic rock or hard rock tones. The thing is, even the Master Volume model JMP is still an extremely loud amplifier. You either need to be in a soundproof room or have a good power attenuator to get the cranked tone at a more manageable volume level. The controls are pretty straightforward and act as intended. I find they can get kinda harsh when turned up so I prefer to keep the treble and presence lower when I've turned these amps up to stage volumes.

SOUNDS

This amp sounds killer for that raunchy British powered rock style used by so many bands back in the day. I would say it is a bit of a one trick pony but it does that trick very well. These amps get gain from volume, so naturally it will sound better as the volume is turned up, definitely. It sounds great with a variety of guitars, but the combination of this amp with a Gibson or other mahogany humbucker loaded guitar is awesome. Definitely the ticket for rock and early metal tones with that classic EL34 bite. These amps also make great mod platforms to be turned into high gain monsters too.

OVERALL OPINION

All in all I think the Marshall JMP is a great sounding and ultimately one of the classic Marshall amps of days gone by. They can be had for about a grand used which is a good price considering how good they sound and how iconic they are. You might want to budget for an attenuator to really get the most out of one of these, but when you do, look out!

An all-tube between vintage and modern. It is also quite comfortable with good old pedals (big muff, vox ...) for the big powerful well a bit saturated naturally with its two inputs (low and high)
The 100 watt power are ideal for this type of material, it lacks a channel may be saturated or more punch in the saturation, but hey, ream it with a good distortion is doing great!

UTILIZATION

The minimum requirement for a fonctinnement obtimal. (Without unnecessary complication to my taste)
With 6 pots, presence, bass, middle, treble, master and pre-amp sound setrouve as soon as the button "on-off". Those who love the simplicity is served, maybe a reverb will not be too ... but hey, it will betray the very ethics of these models so well known for their natural.

SOUNDS

So that a particular grain is not unlike the sound of the old old school marshall of yesteryear, but with a modern twist not too exaggerated that leaves an individual carctère this amp head. I used both for good old blues rock with punchy double or even triple over saturation phaser, delay .... It all cash without flinching! [/ B]
A clear, beautifully pure, in charge of mediums and serious even if you have to push them near a bottom!

OVERALL OPINION

My head in 1980, I got it used in 2003, I have never regretted.
This is my first personal all-tube, and I'm not ready to let go!
Personal opinion: if used properly, can do a lot of things, was not afraid to have pedals!
