User reviews on Marshall JCM900 products

For life (Marshall - 4100 JCM900 Dual Reverb [1990-1999] [2003 - ? ])

By psYchoActiF, 25/04/2014
All lamps, although 90's. Sharper than the JCM800 series. 100W, impossible to fully, but can adjust to 50W.

UTILIZATION

Equalization is very limited, but the sound is there.

SOUNDS

I have the combo version with 1 HP, combined with LAG The Beast Supreme Custom Shop 97 too, ba it smashes.

OVERALL OPINION

Bought in late 1997 after a summer in the fields of cocos in Brittany, this amp is always with me, and I do not divide them. A small problem during the warranty after service return that say ... Almost 20 years ago, and just a change of lamps. Indestructible.

Rediscover it! (Marshall - 4102 JCM900 Dual Reverb [1990-1999])

By GregVal, 18/02/2014
100W tube combo (mine has 3 x 12AX7 and 4 x EL34, but there are also versions with 6L6), switchable to 50W.
One input, one non-switchable effects loop with adjustable level, 2 speaker outputs (8 and 4/16 ohms), one direct line output and one with amp simulation (I haven't tested it) and that's it.
On the front panel, a clean gain, a drive gain, an EQ (bass/mi/treble/presence), volume and reverb level per channel and that's it (which is more than enough).
As for the speakers:, 2 Celestion G12T75 (a very questionable choice by Marshall).

UTILIZATION

It couldn't be easier to dial it in, given that the EQ (as is often the case with Marshall) is useless (I'll come to this later).
The clean sound can crunch gently and be even a little biting, but that's certainly not its main utility. Likewise, the gain level of the drive channel is easy to gauge but it will never tickle a Recto or any other Hi-Gain amp... Contrary to what its name might suggest, this amp is intended for big rock, stoner, punk, but not to extreme metal, not without external "help." that is!

SOUNDS

In terms of sounds, you could be disappointed by two things: A pretty tight clean sound and a drive channel that doesn't have too much gain (a typical Marshall characteristic), despite yielding a really nice color with the gain between 1/4 and 3/4.
But you do need to consider THE main defect of this amp, namely a completely useless EQ. Moving the controls won't affect sound in the slightest, but not moving them at all will make them rust and produce crackles...
However, inserting a (good) EQ pedal in the effects loop will change your life, I really mean it. Clean sounds can take a different dimension, reducing a bit (or more) 800hZ and increasing 3.2 and 6.3kHz. Personally, I have found more than one funky sound with this combo. It's obviously not a Twin, but it's pretty acceptable.
Anyway, don't hesitate to use good drive pedals. A TS-9 on top is an excellent choice, both for the clean channel and to boost the distortion channel.

OVERALL OPINION

I've had it for a VERY long time (more than ten years) and I have even had the amp head version (4100). I just had it retubed and checked. The technician told me it was originally biased too cold, which could explain the sound stiffness and a lack of gain. Don't hesitate to ask your guitar tech about it!

Today it has gotten back on its feet and it's a real joy, despite its size and weight. Its useless EQ still bothers me, but the amp works fine with pedals, and its ultra low character could make it an excellent choice if you are looking for a typical big rock, punchy and reliable amp!

Baffle means (Marshall - 1960A JCM900)

By fabbcrich, 12/02/2014
I do not own personally, I had the opportunity to used 2 times at concerts these speakers were a provision

I played a lot of speakers, Laney 412 lx, 412 Valvestate 412 Carlsbro GLX, Peavey Valveking 412 Mesa C90, 212 Marshall with 1 V30 and 1 eminence legend, my personal 212 made myself with G 12 T 100 HOT, and another 212 made by myself with G12 K 100

Treble and midrange are well ahead and grain amp spring as it should on the other hand there is little low for a 412 (my 212 has a little less treble and more scooped but more low even with only 2 HP), otherwise the sound is good, fairly straight and accurate but not as much as in clean distortion

I would not buy this new 412, too expensive for what it is and the sound I want, I put him 7/10, it is not bad but it lacks too low especially for a 412, my opinion holds account the baffle itself not the value, € 400 and used a little improvement (wiring, stiffen the body and make it a vent at the back to get low and deep) I think its worth it, but I prefer to make my cabinets myself

A good speaker but no more (Marshall - 1960A JCM900)

By Maélio, 04/01/2014
How long have you use it? What is the particular feature you like best and least?
Cla makes fifteen years that I have this cabinet. Used with various heads (Marshall, Engl, Mesa Boogie ...). I must admit it does work in all circumstances. Tough, tough, no surprises. Used in mono or stereo, 4, 8 or 16 ohms. A big advantage.
The structure is strong. The Tolex much less so. Grid, upholstery, wheels, get damaged very quickly, even being careful.

Have you tried many other models before buying it?
No, first baffle purchased new. This is probably the most accessible to all budgets model. Timeless, and above it is found easily on the market. Used and it is very affordable.

How would you rate the quality / price?
With experience, you do again this choice? ...
That is the crux of the problem. this cabinet does the job. But no more. It is found everywhere live in concert halls, rehearsal rooms, so you know what to expect.
At the same time, it is very versatile. Often loud, it can be a reliable friend as a cutter heads (!). If you put it on the ground, it will return a very serious and warm sound. However, at head height, it is full of sharp, drooling, screaming and quite inaudible. So live or in studio, careful where you place microphones!
For metal, there are so many other speakers, to much more expensive price. It is true that we have a chance of breaking this kind of cabinet when playing live. So much tame, it's simple. But for the price of nine, there are so many better speakers.
From secondhand, it is found at a very affordable price. I sold mine 200 euros. But I have tried many others. Other speakers have a much more colorful palette.
Everything depends on the style of music you make, but you probably find more suitable for little more expensive (for the metal, try more ...)
