M Elise's review
Its a solid well built Marshall amp with straight forward controls.
This was my first Marshall. I bought it in the early 90s (along with the matching 4X12 cab) and have long since sold it and replaced it with the 30th Anniversary Marshall so I'm writing from memory here. I was immediately disappointed with this amp when I got it and never warmed up to it. I wanted a Marshall that sounded like the classic Marshall sound of the 70s and assumed that all Marshalls were basically the same. I had no idea that Marshalls could be so different. Now I am wiser but poorer. This 900 Marshall sounded nothing like the classic traditional Marshalls which are based around the EL34 tube. The tube in this amp is more like a 6L6. The distorted sound is harder, more aggressive, darker, with harsher harmonics and for some reason the amp seriously lacks bottom end as well. Oddly enough I loved the clean channel with reverb which sounded beautifully liquid and almost magical at times but who buys a Marshall for its clean sound?
I have also come to realize over the years that the cab I bought was wrong as well for the sound I wanted because it has the now common Celestion G12T75 speakers which are best for metal but not 70s rock. Marshall speaker cabs of the 70s used G12H30s or others that sound entirely different. You live. You learn. You spend gobs of money.
This amp was not my cup of tea. However based on other reviews I've read some people apparently love it . Its clearly a love it or hate it thing with this amp. It depends on the sound your after. The bottom line is that you've got to realize that Marshalls from different eras sound quite different from one another and so do the speaker cabs depending on the speakers. To get the sound you want you've got to get the right model amp and the right speakers.
MGR/Anonymous's review"Marshall JCM900"
I like the distortion voice on this amp with its ability to give you a modern tube amp sound.
I also like its ability to give you 2 choices a clean and distortion sound at the stomp of a switch.
The thing that i dislike about the unit is the clean sound which tends to sound a bit "tinny" on its own. However, in saying this the clean sound can be beefed up by adding different effects with it i.e a tube screamer.
During relatively loud volumes my amp has a rattle or buzzing sound and im buggered if i can find out where it is comming from. I took it to an Marshall amp specialist and even he couldnt find where the rattle is coming from. The rattle can be only heard when Im close to the amp, and hence, it hardly bothers me.
My Marshall has been good to me and has never broken down after 6 years of in and out of boots, tipping over, kicking and dropping once from 1 metre. It has a distortion sound with balls and a clean sound with none which can be overcome with effects. If your thinking about buying one test the amp to make sure it doesnt rattle at a good volume.

Equalization is very limited, but the sound is there.
I have the combo version with 1 HP, combined with LAG The Beast Supreme Custom Shop 97 too, ba it smashes.
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.

benswamp666's review (This content has been automatically translated from French)" Very good versatile amp"
Amp 100W, 50W in swtichable (triode: loses power but also the characteristic)
2 foot switchable channels.
Channel A: clean -> crunch
Channel B: crunch -> overdrive
Loop insertion effect balance with -10 / +4 dB
2 amps easy to use switchable channels
Suitable for Blues, Rock and even Metal.
Used since 1998
What I like: Channel A cranked overdrive with a good front.
I also like: changes made to the channel B (diode bridge split) which gives a closer rendering JCM 800 punch.

guizmo238's review (This content has been automatically translated from French)
For my part, the configuration is quite complicated .... I have two speakers who will lead in 1960 with A + B. ... connectivity is quite complicated, I had to look on this site for the information necessary .... but with good advice I got I am absolutely very happy!! I did not get a manual with but at the price I paid I even had the 1960 A cabinet with!! sound of the amp is very good if you look for rock sounds .... but we must add effects to get the big sound ... its very hot and the distortion is effective wish a very good clean and also easy to find!
I like metalheads and rockeux .... this is the amp of choice for my type of player .... I use a digital delay, a chorus and a set of preamp eq ... j ' addition follows a ibanez tube screamer overdrive for Narrow my sound and have the teeth to the metal ... the sound is really good ... in 25 years it is my hobby and best sound is the sound I was looking for! !
it's been 5 months that I use and I'm very satisfied ... nothing to do with the small combo amp and other fine good cheap!! that I like the most is that it is big, yes, but the sound is diffuse Surprisingly ... with 8x12 inches behind the ca pouuse and spreads halucinante way!!, as I bought it used, I can not I really pronounced on the value for money but in my opinion worth it ca pay dearly for this type of amp .... moin has to have a changing temperament, he will follow me all my life I think so! !

helium system's review (This content has been automatically translated from French)" Almost 20 years of loyal service"
I'll spare you a description ... eq for each channel it could be fun! but are not!
There is no simpler, no need to adjust the hours it sounds!
I played noisy, punk, rock, indus, with a rise of 70 SG DiMarzio, a Mustang Us, a Heritage ... and never disappointed! In Briefly, crystalline or clean sounds I do not know, although with the Mustang and the channel A of the amp the sound is more than respectable wholesale with single coils it goes well, we can play funk fusion Red Hot ... but we chose not to its characteristic crystalline Marshall ...
I use that since there is, I'm also JCM800 master volume and a few others but this one I do not loose! The scratch who tested it all appreciated . But then I tested the version with the 5881 and there I found no sound, nothing to see, I also tried the 2000 I can not find it better with buffs that are useless if not have a sound yucky!
This is an amp that is not expensive OCCAZ and with a good selection of lamps it does! Otherwise the little negative point is that the knobs spit, as usual! After years of bomb I'll have to contact me decide to change them!
Don_Viviano's review (This content has been automatically translated from French)" Criticized, but cool nevertheless"
2 channels, common equation, separate gain, reverb separate separate volumes.
Rather summary, I like!
I am using the crunch that obtained by pushing the gain (7-8) 1 channel.
Channel B is truly Hi-Gain, it throws up the distortion.
Treble 7, 7 Middle, Bass 5, 8 presence.
For rock 'n roll, the setting is impeccable expressed above.
I play it on repeat with my LP Studio (micro BB2).
A good crunch though this rather modern (fine texture). Beautiful shine and beautiful presence, I genuinely like. I obtained by pushing the channel A (which must be the clean channel ??!!)
Not tried the clean or hi-gain (not use it). And while many decry
this amp, I find it wrong. If I had one complaint to make, it would be the grain a bit too tight.
But otherwise bore the crunch mix well, it's more enjoyable. With a boost upstream, we have a good lead sound. He collects well as the fuzz, it looks like he will die or that HP will be torn apart.
I play it in repeats 1 time per week is the amp of the studio.

fabou13's review (This content has been automatically translated from French)
tube amp: 3 in preamp (instead of 4 for a JCM 2000 or JCM 900 SLX) and 4 power (EL 34 for mine).
Impedance selector to play 50 or 100W. Personally I prefer to leave it on 50W.
Purchased 400 secondhand €
2 channels: clean and lead A B each with 1 volume (Master), 1 win and 1 reverb
EQ common to two channels: a problem if we want a channel switcher to another, the sound is too much dispute.
It is perfect for my style hard rock (ACDC, Airborne, Led Zep, ZZ Top etc..).
I use a Gibson SG or a Start 61 U.S. and two with the sound I like. All in a baffle 1936 in Marshall Celestion Vintage 30 (I did not like with the G12T-75).
29/11/2010 (after 1 year): ca does very well with G12T-75, especially 4x12 is less dry, more open.
I use only the channel B Lead. Like not at all push the channel A, it sounds too loud and clapping for my taste, so to get a crunch on channel B I drop my guitar volume knob (with the SG that sounds wonderfully well for the TDCA).
What I love about this amp is that the sound is well defined, and cuts into the mix. What is missing is a little "soft."
29/11/2010: it's actually the v30 gives this side snapping, dry ... it is sweeter with G12T-75.
After 10 months I use repeating and concert, I do not regret that choice at all.
Before I had a JCM 2000 TSL 60 (with 2 v30) is the sound was good, warm and mellow, but too often "fuzzy". The 2000 is missing a definition for playing power chords in the TDCA.
The pros: well-defined cuts in the mix, good value for money
the -: EQ unmanageable if we use the 2 channels (it's not my case)

blaez_minkoff's review (This content has been automatically translated from French)
For the power (which is all-tube):
A 12AX7 phase inverter followed by a push-pull four EL34 (the 5881 U.S. model).
The tone stack is not what I've seen better. Do not hesitate to set equalizer to max or zero. I see so many guitarists who do not dare turn the knobs and put everything at noon.
The clean sound is not up to the race condition JCM900 but was not designed for that. This is an amp for lovers of Rock and Hard Rock distortion.
I have since 1999. Buy € 530 at the time with the baffle 1960A.
By dint of perseverance and testing of any kind I finished not find a config that pleases me.
Fender Jaguar Boss SD1 + modified + clear + channel JCM900 Cabinet Mesa Boogie 1x12 Thiele.
I never use the boost channel because I find it lacks dynamics and spring mixes poorly. In short, the boost channel did a lot of noise but nothing is heard.
I change all the preamp section for it to be 100% lamp except the reverb which remains transistor. It remains only a single channel like a JCM800 but with two gain settings and two input (high & low). Here was a lot of work but I am happy with the result for only 20 € component by taking the best quality. As against this no longer really a JCM900.
I made a post about the transformation for those interested:

hardcore666's review (This content has been automatically translated from French)
Dejate everything said about her
The JCM 900 is very simple to use, very simple
Regarding the sound, it must be admitted into clean is a bit stiff at the base, and not saturated trs a metal base that's true ...
For it is the cons that have become interesting, using the JMP avecun 1 and 1960A with a more or less different guitars: Jackson RR with emg 81, emg HZ LTD7 strings, Gibson Les Paul Standard and a squier strato di Marzio with a microphone, the sound is really metal and hardcore!!
Ke the fact the sound is not typical in trs clean, my friend, a JMP that does the job and it really trs trs well lol
It sounds really metal, TRS big sound and the JCM 900 trs filled out its role of power amp!!
He is strong, too even, but its role APRS all.
Try for others like peawy, the mesa and other JCM 900 is really the height, if you like big fat are well and that we love against less acute Submitted too, the JCM 900 and JMP 1 are unstoppable.
It passes easily obituary Hatebreed and really does not sound like fear or deftones slipknot ...
In 10 years of loyal service I do not resell any time soon!
It is beautiful, sounds like hell, and impresses with its simplicity and power <img class="smiley" src="/images/audiofanzine/interface/smileys/icon_wink.gif" alt="wink" />
I also possde peawy, trs good too, but different, the JCM 900 is built for him laseine !!!!!!!! <img class="smiley" src="/images/audiofanzine/interface/smileys/icon_mrgreen.gif" alt="mrgreen" />
I got it used, I board is jamaist deu
If you like Marshall, metal, EMG lol the JCM 900 amp is a really great !!!!!!!!!!!!!!!!!! <img class="smiley" src="/images/audiofanzine/interface/smileys/icon_mrgreen.gif" alt="mrgreen" /> <img class="smiley" src="/images/audiofanzine/interface/smileys/icon_wink.gif" alt="wink" />
Do not hesitate if you see him, it will be a great companion!
