MGR/stratcat5150's review"Marshall JCM900 50 Watt 2x12 Combo"

Marshall 4502 JCM900 Dual Reverb [1990-1999]
traded old valvestate head plus 300 at field of dreams in fairfield, ia. I basically stole the head when i bought it so didnt get hurt on the deal at all!!!! MARSHALL TONE in a portable box.

MARSHALL TUBE OVERDRIVE!!!! The dual reverb is nice as well, but doesn't come through p.a. well. very impressive when paired with an older marshall 4x12 w/ greenbacks, more for looks than anything else...did most gigs w/o the cab. you can get a nice spanky sound from the clean channel, or drive it a bit more for a decent rythym sound.

clean channel doesnt clean up well without losing tone and a bit too much gain for my taste. i tried a bbe sonic maximizer and was pleased, but bought a les paul instead of an extra piece of outboard gear.

built like a tank!!!! this thing has been dropped, had p.a. cabs fall on it, been rained on, drank more than its fair share of beers, and always fires right up...overall good amp for the right deal...have since switched to marshall/mesa set up for cleaner tones, and a little extra punch for solos.

I prefer the 50 watt version so you can get a bit more from the tubes without killing evrybody. Good overall amp served me well for a lot of gigs with 0 problems!!!! The valvestate i traded in for it went down all the time. I would recommend this amp for all but the most serious tone freaks...well worth the money.

Metal fury's review (This content has been automatically translated from French)" Very good!"

Marshall 4502 JCM900 Dual Reverb [1990-1999]
It's known, I do not see what I can add!

I spent 25w because the seller had bought the lamps need! its beautiful!
It is very simple, good saturation, but you have to play hard .. ca is heavy ..


I use the easiest way it is!

No pedals! just wha wha! That's it! ESP and Marshall do the rest!


I play Metallica (mostly) and our compositions very close to it.
I play an ESP Eclipse with ringing of the fire of Jesus!

The sound is good but you have to really push hard for the typical sound of the JCM .. not in the room!
It sounds great for loose strings etc but for my friend plugged in a 112 bandit attack more! I get a limit next to him .. But the solos etc! a treat!


I have 2 years and I just bought a Blackstar HT 5 level for the sake of "needs to be to burn for a big sound"!
I've always looked for a JCM 800 because I love the sound but the price being what it is the JCM 900 is excellent!

It is robust, simple, accurate, the reverb is good, the texture is great, but it lacks a bit of attack for blocked for metalheads if not for the blues and company pff it's great!

AVmetal92's review (This content has been automatically translated from French)" A slap in the ..."

Marshall 4502 JCM900 Dual Reverb [1990-1999]
100% lamp
Two Celestion speakers! :)

two outputs direct out (in bad quality ...)
an effect loop send / return
a switch 50W/25W
etc. ...

Maximum power: 50W (25W switchable in, yet happy because 50W is ... TOO!)

Two channels, one clean and one lead
Reverb, gain and volume to the two independent channels
EQ shared between the two channels (if you change one, you change the other person ... it's a shame but the equalization of the clean channel suits me very well lead)
No effects except reverb (it is fulfilling its role, pleasant to listen)

Included footswitch: channel and reverb (the reverb turns on or off for both channels simultaneously)

I put 9 because I wish to go through an exit direct and via a DI out directly on the mixer, but in this case the sound is better through the good old celestion and microphone. 9 because of the shared EQ also ...


Configuration very simple, it turns, it comes out, we're happy or not, if not: you go back and it's good:)

Manual? What manual?

Within hours the amp is under control ...


The clean channel is a real slap in the face ... It's not clean fenderien, but ... Here, it speaks for itself:) It's very sweet, crunch it too (unless you get on the gain but hey ...), it's just wonderful ...

At the lead channel, the gain goes up to 20 ... so it's heavy, very heavy. I do still goes that far, and with the gain to one hour / two hours, it sends the bass distortion fairly clear, beyond it gets a bit sloppy and fuzzy boundary ...


I have since the beginning of the weekend, I spent all my time to test it and to enjoy happiness.

I've had in my possession that transistor amps (Marshall, Line 6 ...) but I had the opportunity to test the Fender Super Champ XD (lamps) of the second guitarist in my group, and are not photo, it plays at all in the same register at the ... So clean that distos available:)

I traded a Gibson Les Paul cons Studio 2009 + 70 €, I could not pass up a Marshall all-tube, especially since in the end, the sound is exceptional, and that the JCM 900 are no longer in production long ... I was told that it dated from the 80s, but knowing that the JCM 900 series was launched during the 1990s that ... So an amp that should be within 20 years and will be extremely valuable in the coming years!

Marshall 4502 JCM900 Dual Reverb [1990-1999]




Of course the distortion is not original but then top with a boost from the Dunlop's another machine that takes a different scale not need much to have a clean amp that boost in enregoistrement I keep this amp for the high register of distortion coupled to an amplifier that possde high low filters whose frequencies are obtained it on a t putra big sound

Breizh Atao's review (This content has been automatically translated from French)

Marshall 4502 JCM900 Dual Reverb [1990-1999]
APRS quite a few years of practice, I finally found the AMP!

The JCM 900 Dual Reverb combo is a 100-watt lamps 100%: The big sound!

The amp IDAL to blues, rock and hard (the AC / DC).

This amp has a clean channel and a channel saturated.

Each channel has a rglage indpendant gain, volume and rverb.

The rverb is warm, the sound is prcis be it plain or saturated.

The qualisation is common to both channels, it can be the weak point of this amp.

I do not put 10/10 to remain objective regarding the qualisation although I did not feel any stress or ESG in my game


This amp is very simple to use!

In my case, I was looking for a good clear sound and a large saturation, I do not have the t!

As each channel has its SETTING THE gain, volume and rverb indpendant, the sound is easy to get.

For qualisation, we must find a compromise and take into account the sound of the guitar mic (bridge / + acute neck / + severe), but overall it's all done Grable!

In my case, I had no manual and I do not feel the need, in 10 minutes, quarter of an hour maximum, my setup sounds (silent bright and saturated ok.

Namely, this type of amp needs to have the warm sound! When you arrive in RPET, THE FIRST thing to do before installing the rest of the stuff and chat with friends, is turn your amp, and you will be surprised by the extent of his rich, deep and powerful!


This amp is made for particulirement play blues, rock and hard!

I play on a guitar LKV ( is a guitar with two single coil and Benedetti guitar and amp combination is magical!

I tried it with a gibson ... say anything, the couple IDAL!

I find its own clear, deep, round and rich prcis with reverb. Mrs. Russ I make it sound a kora (African harp 21 strings) ... I tell you this amp is the top!

The sound is a saturated and trs trs prcis also incisive.

I give 10/10, 12/10 see if I can!


I played with for 6 months.

What I love the sound! The ease of use!

What I like least is the weight, fortunately there is a cot in each fist!
But then we get something for nothing ...

Before buying it, I play Musicman (its too "flashy" I got, Vox AC30.

I also liked the Vox but rpondait evil power of my microphone and it was really cold, warm it for a long time and especially the sound is not the same price!

The report price is exellent quality! You will find between 400 and 550 euros depending on the state and frankly for the price you will not find better!

I'm really happy with this choice and j'espre go a long way with this amp.

Marshall 4502 JCM900 Dual Reverb [1990-1999]
Amp lamps
I tried this amp in the store there this year when a friend of mine was looking EQUIP YOURSELF
I tried this amp on a guitar Vigier Excalibur


Usage is rather simple being given the number of correct SETTINGS


This is where it was stuck ...
the sound was clear through, it was nothing special in fact, neither ugly nor fabulous.
the lead sound, for against, was really horrible. It was like the sound of 10W amps really low end. at that time it has the look me and my friend and we wondered if it was not a joke ... We asked the seller if there was not something cass in because it was really horrible. And he answered, "but nah, you're crazy, c is the sound of Hendrix as you listen, c is the legend marshall ...". good recess, it was not bought the amp.


We try the amp barely 20 minutes. It was too unbearable. the salesman insisted pourqu'on continue, but he begged to fuck this amp the trash!
on the other hand as I said above, I suspect the model we try to have t failed. Or the amp is really the most miserable I've ever tried

cricri83000's review (This content has been automatically translated from French)

Marshall 4502 JCM900 Dual Reverb [1990-1999]
3 12AX7 or ECC83 in the pre-amp section and two EL34 for the power amp section.
It has 2 Celestion G12T-75 HP
It is 50W (gives a lot)
Connections rather simple footswitch imput and the front line and two output, two effects, and two impedances rducteur power for the rear face.
A clear channel and a channel saturated with reverb.


The rglages are simple and effective.
yes the sound is not hard out.
We do not need a manual.


It should all styles.
Sre it with the grain of the lamps it is very well for the good old rock.
For the part I play guitar with a Aria Pro II ZZ Deluxe. (Not great but not too way ...)
For the part because I play with a GE-7 (gualiseur) of BOSS and a ZOOM 606 same as prcdement.
I get a lot of different sounds and Varis.
Sounds too dull ...


Trs little.
Obviously I like the grain on the other hand I do not like the weight of the BTE, but it takes at least a.
oui.Marshall transistors double and triple body and Fender twin reverb including lamps, Peavy, Applause ????? and many others
Excellent .....

nicolashotmail's review (This content has been automatically translated from French)

Marshall 4502 JCM900 Dual Reverb [1990-1999]
Lamps with 100W Marshall amp footswitch 2 hp 12 "celestion
Effects loop and power rducteur (trs not effective at all) and reverb
To crunch or saturation of 'rock' is pretty clear but the sound leaves a lot DSIR and there must be full price for a saturated correct.
I connected to a closed hp marshall 4x12 "celestion and it shakes a lot more volume while disto ...
If c'tait again, I will therefore take the two bodies but think this is not the amp of my dreams ...


Simple to configure with channel equalization.
Manuel? What manual? not need manual.


Top top not for clean sounds and distortion for Triqui (take 2 bodies, closing the box changes everything).
Jou with a Les Paul studio and a strat: better with the Les Paul


That's it, I sold it ... for better than worse.
I will not go that choice.
At the same price, turn to the classic Peavy or Fender.
