Marshall JCM 900 4100 Dual Reverb

I love the 900. i dont really mind the shared EQ that much because it still sounds so damn good switching between the two. if it really bothers you to use a shared EQ, pay more than twice as much money for a 900 and buy a triple super lead.

I play a stock gibson SG standard and a mexi strat with lace sensors, l.r. baggs piezo bridge and i run my 900 through a 4x12 mesa cab. Two effects: the morley mark tremonti wah (which is totaly wicked) and a BOSS metal zone (if you consider a distortion pedal and effect). ive stopped useing the metal zone because it sounds too... old school metallica meets solidstate. I play anything from blues, to rock, to metal, to hardcore and the amp sounds damn good for every style. Not a lot of gain but if you want a lot of gain, again, pay way more money than you really want to and by TSLs, rectos, etc. I don't understand why people are saying the clean isnt really clean. I also have a fender from the 70's and i think the 900 is just as clean as the fender. So i have come to the conclusion that people are retarded and they dont know how to use this amp. i have turned this amp up to 8 (its 100W) and it sounded just as clean as it does on 2. The only thing i need from this amp is a small push of gain for solo work, thats nothing a duncan pickup booster cant fix

no problems except for when i bought it, it had this crazy buzzing noise because the guy before me didnt really take care of it, it had a buch of dirt on it and sticky stuff all over it, most likly a spilled pop or beer. it turns out there was a hairline fracture in a line in the circut board, no biggie. since i've fixed it it sounds brand new and the amp repare man fitted the 900 with JJ 6L6s. I dont know much about tubes, but these sound really good

ive never delt with marshall but if i did im sure they would be very helpfull

I have been playing for 6 years, im 17 so i don't have much money. If it were stolen i would cry, then buy another one. I really love turning my overdrive channel up to 6 and 8 (havn't made it to 11 yet) and listening to the amp bark out this nasty bottom end. ive owned one other amp that i sold to get this one, it was an old school mesa studio .22 that was a great amp, sounded good, but i couldnt play with any bands and so i need more wattage. there isnt one thing i hate about this amp, the lack of gain for solos isnt a big deal because it still sound raw straight through. if you are looking for one but havent herd it, listen to AC/DC, its not the same amp but it sounds very very close

Not sure on the date,traded an "AVT" 50 Head and "MGD" 100 WAT "A" cab for the "JCM" 900 used,but I've owned the JCM 900 for about a year now. I have found it to be unparalleled in sound quality.I unfortunately damaged it in a gig move. Still waiting for "PARTS", but I think what ever the cost of repair it's well worth it!!! The sharp highs just blow you away,and volume is outrageous!!! I've tried to imitate the sound, but have been unsuccessful. I Think this Amplifier is a 10.

I use a Dean Icon ,Dean EVO,Les Paul Studio . Each has it's own sound but the 900 brings out the best in each one of them!Playing things from Cooper to Ozzy to Alice in chains I can expect the best from this AMP!!

Thru my own fault I await the bill for repairs . I otherwise have never had a problem with this model!!!

Unknown

I find this Amp to be invaluable to my band and myself.

I don't know what year my JCM 900 4100 is... thinking 80's... but I've gotta tellya...as is...it knocks cigs outta my ashtray at 6 feet away!!!...which is what I was lookin for!!!! I was looking for tubes with "POWER"... with intentions of using pedals I've enjoyed over the years! Sure you can buy "Boutique Amps"...that will create those perfect tones you need...BUTT...who in this economy can spend 10grand for Dumbles...or Bruno's or etc.etc.etc. shall I go on? We all know that Jim Marshall is the Father of "LOUD" & thats watts that!!! My preferance for over 32 years of guitar playing has always been FENDER...period!!! But for the origanal sucker punch to your face....it's always been MARSHALL!!! Wait till those tubes get HOT!!!!!

Jimi Hendrix got me going in 1968...not only that...a local guitar hero in Brooklyn, NY was gettin all tha girls!!! I finally fixed his butt when I got my 1st Fender Strat 1963 & a FenderDual Showman after working my paper route...then I heard of "MARSHALL" I bought my 1st. JCM 800 and fawgetabowdit!!! Sweeted my style...no noise...75% up on everything...then WOODSTOCK!!! Clean channel needs my boxes but will definately do a Pete Townsend...distoetion is minimal but that's why I love my boxes!!!

Jesus blood never failed me yet.

Never needed any support...I STAND ALONE!!!

32 years of playing guitar...to many other Major Amps to say...

From what I've heard I think mines a '96 model, it has 6L6's. The amps pretty versatile, but its just a simple amp, no real features. Its just two channels which I guess was great after having only one...

I dont love the distortion channel, its just ok. This amps cool and it barely meets my needs. The clean channel kinda sucked too. It seems on the lead channel it lacks bottom end and on the clean theres too much. My clean channel is messed up though and it has a boost of gain. I use this instead of the normal distortion channel because it sounds so much better and is way louder. It sounds like an old Marshall should. I have a Gibson Les Paul with an EMG 81 in the bridge and helps to get a tone that I can live with. I have a Peavey 412MS cab and a Marshall 1960B cab. Both cabs sound totally different and its hard to say which is better. I'm trying to get a killer tone with amazing depth and clarity meanwhile with a lot of punch. The way my gear is right now is it does that, I would totally keep this head around for certain styles and whatnot. Its great for vintage rock.

I've had this head for a few years now and its great. Nothing major has ever happened to it to make it stop working and its been played at a bunch of shows. The only thing is that the clean channels messed up but thats only made it better. Not sure if its something i can rely on though.

Never dealt with them but they should be fine because they're a huge company.

It all really depends on what you want your sound to be. The JCM 900 is a fairly versatile amp but I think its best for rock. Nothing too heavy, nothing too soft. Although it does do ok for heavy and soft music. The way my gear is now is its fine for heavy metal and hardcore, punk stuff and its amazing for vintage rock.

? I think that this amp was made somewhere in the first 90's (91-92)

? If you want a HARD ROCK sound, this one is probably one of your best purchases. But don't expect it to make all music styles, no amp can... My music style is contiously changing between Heavy (classic one) and Hard Rock, and the sound is very very good, but IT'S VERY NOTORIOUS THAT IT SHOULD NEED A 3rd CHANNEL!!... because it lacks of gain, mostly in lead parts. I sometimes would like it to sound more distorted, but i won't put any stomp boxes which could colorize or dirt my sound.

? I have written about the channels.. well, it has 2 channels, the first one made for cleans and soft dirt sounds, and the "LEAD CHANNEL" supposely made for soloing, but IMHO is best to make gain power riffs, but not at all shred...

? It also comes with a dual reverb (2 reverbs, one for each channel), which is very good. It's slightly useless when your knob it's higher than 5 (12:00) because is a powerful reverb which will destroy your sound if you don't put attention to it.

? About the power.. damn it.. it's one of the most powerful demons out there... it's 100 Watts, but it sounds like a bomb. My cabinet is a 375 watts 1960A 4x12 Marshall cabinet, and I think i could completely destroy the speakers with this amp... The only problem is the gain level... less power and more gain could be great,,,

? I'm going to change it soon for a rack setup. Concretely a Mesa Triaxis preamp + 2:90 Poweramp. I don't have enough money for them both, that way I'll buy the triaxis at first and use it in the FX LOOP of the Marshall (which, BTW, it's a great FX LOOP; slightly noisy, but still good), taking the power from it... Next i'll buy the 2:90 and sell the Marshall...

? Finally, the 6 is for the ABSOLUTE NEED OF A 3rd channel...

? My gear (i will talk just about my MAIN gear)is next: My guitar is a PRS STANDARD 24 with HFS and VINTAGE BASS pu's into a MORLEY BAD HORSIE wah. From the wah, the signal goes directly to the input of the marshall. In the FX loop i have a ROCKTRON INTELLIFEX XL as effect processor. My cabinet as i said before, is a Marshall 1960A 4X12.

? About the sound, i wrote hard above... If you make Hard Rock, go for this amp (KISS, ol' SCORPIONS, ol' JUDAS PRIEST, etc..). Don't buy it if you're a metal-head, a shred guitarist (if you hate stomp boxes), or a DEMON-DISTORTED-SOUNDS lover.

? Note that this amp is also good for blues sounds when setting low.. it's a very good one for that, considering that the rest of your gear (like your guitar) is very important for that too...

? I finally put it a 8 because what it can do, it's one of the bests, but it isn't versatile at all for heavier (or very soft) things..

Well, I have had it for a lot of years (at least 4-5) and it's like new.. i put a 8 because it sometimes break the fuses, but except for that, it's like a tank (it also weight like a tank)...

Never dealed with them...

? What can i say of this amp that i don't said above... it great if you feel that it fits your sound... it's bad if you think it lacks of gain or pristine cleans,... I'm done.

Same as other 4100 Marshalls

When I first got this amp I didn't like the sound. It was very bright and it came stock with el34. What I did was change the tubes to JJ6L6GC which cut way back on those highs. Then I put a Boss SD-1 in front of it to boost the overdrive. Level all the way up, Gain 9 o'clock, And tone to taste. Just keep the tone down or else it will get get feedback(your call). Just with those simple changes this amp sounds totally different then when I first bought it. I wouldn't think of getting rid of it now.

I bought it used with the original marshall el34 tubes still in it. When I replaced the tubes to JJ6L6GC and re-biased it, It didn't seem to have any work done to it. I think it is 12-13 yrs old.

Never had to deal with them

everyone was telling me to keep the El34 in it, But I took a shot at the JJ 6L6GC, and it was a good shot. El34 are bright in this amp which some may like. If you don't like the harsh highs of the El34 then give the JJ 6L6GC a try. And yes!! It still sounds like a Marshall....And a Good one at that.. Hope this helps those people that are in that treble hell I was in..

Features are well described below, it has lots of features and options so i rate it pretty high, but.... it would have got a 10 when i could attach my PC keyboard to it hahahaha

I had 3 of em because i could buy em cheaply back then, all equiped with 5886's (6l6). I used them for a while but was not very satisfied with the sound in the long run, i used to play em without any stomp boxes. Turned out that the EL34 equipped JCM900's sounded a lot "browner". I had some great fun with these amps but now i replaced them for JCM900 2500 SLX's. These just have more marshall tone (and more drive then those 2204's from the old days). The Hi gain dual reverb 900's have a very high output volume, especially when playing large shows i had all three of em cranced all the way up, this way you can compensate a bit what the 5886 tubes are missing. I am not saying that these amps are not good, they are fine, but try em before you buy em to make shure that the sound is what you expect of it, they just don't sound classic Marshall. I am giving it an 8 because they can sound a bit harsh en when playing at lower volumes they sound very sterile in the overdrive pre-amp section.
I play a Fender Stratocaster with (don't laugh) Squier Japan pickups, they just sound great and everybody wants to know where i got these great classical fender sounding pickups hahaha, this guitar sounded very pure on the jcm's. I also use a Gibson LP with EMG active pickups wich does well for those heavy metal bits, and finally a Marco Messer built custom guitar with Gibson ES135 elements and wich i a real sustainmonster but without the classic gibson look (it looks like a IbZ JS1000 but is better finished and had a glued on neck en hardtail).

It is very reliable. My amps were played full throttle all the time, only thing i had to do is having the tubes replaced because they just wear out now and then, but that is what you get when you burn en that hard all the time.

The company does not give any customer support as far as i know, when you need good support, ask the store where you bought the amp.
I have an engineer checking my stuff out now end then, when using a tube amp you should do so too, just have em checked up once in a while en be treat em with care and you will never need any customer support.

I am playing for several years. I have tried all sorts of gear and still have some great amps, guitars and rigs. I still have one Hi gain Dual Reverb left, sometimes i use it for recordings when i need a different rythm sound or somthing like that, never do rock hard solo's with it anymore. This amp is a good buy but don't pay too much for it. It also lends itself as an amp to mod all the way, other tubes (EL34's), a rectifier tube maybe and Drake Trafo's , then you can make this thing shine.

This amp came form the early 90's, it has the el34 power amp tubes (4) and 12ax7 preamp tubes (3). This amp is good for rock, and some punk (if you want an amp w/ lack of bottom end). I play metal/nu-metal, so this amp suits me not at all. It's got a real nice clean channel, and a "hi gain" channel. it has an effect loop (steals tone), I just wish this thing sounded better in general.

I am playing through it w/ an ibanez artist w/ DiMarzio PAF PRO's, a rebuilt ibanez rg w/ a seymour duncan trembucker in the bridge, and an ibanez rg 7 string w/ DiMarzio Blaze pickups. This amp has a complete lack of bottom end and a serious lack of gain. if you turn it up to at least 6 for it so sound "good" it's harsh as hell. switching to 50 watts does nothing more than make it sound worse. It is a pretty clean sounding amp (very little noise when not playing) overall, if you want this amp to sound good, you need a seperate eq control, and an outboard preamp like a JMP. shame on Marshall for this.

I've only had it about 1 1/2 weeks and i'm selling it, so i dunno

I've been playing for about 6 years, and figured i'd "upgrade" by getting a "hi gain" Marshall tube amp. yeah right. i'm selling it for as much as I bought it for and buying the new Line 6 Spider 2 head. if it were lost or stolen, i'd be pissed because I didn't get any money out of it, but then i'd just go get my spider 2 head.

Everyone should know these already

This thing sounds awesome. I don't know what people are talking about, that the cleans sound fuzzy, just mess around with the nobs a bit. I got the A channel gain on 4 and the thing fucking sound awesome! Perfect tube clean! The distortion I have set to sound very close to the jcm800, and if i crank the gain up more it gives me the newer marshall distortion sound. I love it.

2 years without problems.

It's great. Anyone playing rock will love this amp, if not. Check your ears, because this thing rocks ass.

Mine was made in 1993. Two channels: 1- cleanish, and 1- distortion. Footswitchable reverb for both channels with seprate controls for the reverb on both channels. EL34 power tubes. YOu should know the rest by now...

Set up: ESP Eclipes with Duncan 59 (bridge) and Alnico II (neck) & a Frankien-Strat with a Duncan 59 in the bridge to the 900 to a 1960A cab.

The cleans are ok. Not Fender clean, but then again, it's not a Fender. With a little chorus it get me through a gig.

The Distortion is the reason you buy a Marshall. Depending on how you set the controls, this amp has a wide pallette of tones. I have done ZZ Top to AC/DC to MOP era Metallica to AIC with mine.

My settings: Pres- 3, Bass- 9.5, Mids- 3, Treble- 4-5, Pre gain- all the way up and then roll back a touch, Master- 5-6.

No problems in the six years that I've had it.

I love this amp. If it were stolen, I'd get another one. My only complaint is that there is no 4 ohm opperation. For the money, these are hard to beat.
