Marshall 2100 SL-X JCM900 Master Volume [1993-1999]
100 watt amp, all lamps.
The mine is mounted in 5881.
Single channel, but 2 different volumes footswichables.
Bass, Mid, High
Preamp gain
Gain amplifiers
A Master Volume and Master Volume B.
The amp has a effects loop.


Usage is fairly intuitive.
In my view, the presence of knob is always a 10.
Low on 9 / 10 and the treble instead of 4 / 5, midlles 6. The amp has a tendency to strike quickly if they are not sharp rises above 5 / 6.
Readily obtained a good sound, however, over time, we learn to know this amp and really fine adjustments effectively!
The two volumes are really a plus: I go into volume B (set a bit stronger than A) for solos to pierce the mix!
For cleans, well, you have to play on the volume knob on my guitar! With a single channel such as this, we can have a clean, crunch and a big distortion of just playing the guitar volume pot and passing a microphone to the other!


This amp fits me like a glove. He really has the sound I wanted.
Over time, I learned to really refine my settings.
I played with a standard LP in 2007 and '67 Flying V 1990 and I play mostly hard rock, heavy metal.
The mine is mounted in 5881. I counted, before the amp change for EL34 from all accounts I've read.
When I tried the amp in a cash converter, I fell in love. When I had enough money, he was gone, I waited a year before finding one on the site itself (small annoce).
I kept my 5881 and does not change accounts!
This amp really sounds great. The master volume is really effective. You can have a good sound was reasonable volume.
on the other hand, up 2.5 / 3 on the master volume was very little sound.
The amp sounds very hard, AC bracket, it's heavy sound!!

Many people tend tend to confuse it with the JCM900 dual reverb. This amp has nothing to see, and is, to my taste, well above! It is closer JCM800 with more gain and without the necessity to push the volume very hard to get the big distortion.


I've had maybe 4 years (I do not remember exactly), purchased through this site ad.
It is no longer sold new, in time, it can be found at 500 €, which gives us a quality / price excellent!
I tried many other amps, which, in gorsmarshall: JCM900 dual reverb, jcm200 tsl, jvm, JCM800 ... This is the JCM 900 SL-X was my favorite of all!
I would do this choice several times if necessary. I would even be willing to pay me another.
I'm curious to see what it gives EL34, but I like my sound so I'm afraid to lose by changing lamp!
FYI, I played on a 4x12 "in V30, which goes perfectly (already tested on 1960AV cabinet, cabinets mounted LadyLuck eminence in hp vox, G12H100 but none suited him as well as the V30!
This amp is a great value!!

Marshall 2100 SL-X JCM900 Master Volume [1993-1999]
JCM 900 SL-X 2100 and amended 5Ow passage EL34 (JJ) and Tungsol V1/JJecc83s V2etV3/EH12AX7A in V4. All on a 4x12 JCM900 1960 lead. So 5OW all lights and lamps in every single channel and no reverb but very fxloop loop practice and sound quality. The footswitch activates the second master volume. I put 10 because I like the simplicity Bon Marshall often means single channel! Just missing a reverb but there is a loop ....


Simpler is not possible! We get that great sound you just know how to play and have a good scratch! Equalizer is efficient (only on dual reverb) and games at low volume is possible. Big win and grain Marshall All Tube without transistors, brief but happiness!


I play blues rock, to hard, 80's thrash and stuff like Pantera, also of grunge and it does! Basically it goes from crunch AC / DC to Slayer .... After the styles for even more extreme no problem; a tube screamer or a good pedal to boost and an overdrive MXR 10 "eq in the loop for more low and to carve out pieces and mediums .... It is monstrous! The clean sounds are not the forte of SLX to crunch when it's going to depend on the guitar and play the volume knob works great. So any single channel is not asking either! is "HI GAIN" is therefore primarily for distortion but still with the famous Marshall grain that I like. This is the last good amp Marshall and nothing to do with a dual reverb or anything that has existed .... Soon it will surge as the JCM800 .... It's not my first series in the Marshall JCM900, head and combo, and SLX mk3 and county of origin in 5881 . IT is not the picture EL34 sound even better for dual reverb! The SLX original is very very good too and I encourage you to test it ....


That's happened since Chez Marshall? Not much! The JVM and JCM2000 not the same magic ... Best Head Marshall JCM800 2203 with the single channel! Here is a list of my old Marshall tube: Head JCM 900 DR 6L6; JCM DSL100 2OOO; VINTAGE MODERN 2X12 100W 50W.COMBO DR EL34.DSL 401.JVM 50W .... All KO against SL-X!

Marshall 2100 SL-X JCM900 Master Volume [1993-1999]
Marshall jcm 900 sl-x model 2100

It is an all-tube amp head straight at all (the others are jcm 900 all-tube distortion but requires transistors which nglige the quality thereof)
Dlivre-power is 100 watts (with a switch to limit to 50 watts)
He has 2 hps output (switch 4.8 or 16 ohms)
-D 'output for a transplant on a recorder
-A effects loop
-Presence, bass, middle, trebble, volumes a and b, and gain and master volume.

(APRS to what I was told would come from the sl slash of velvet revolver)

This amp is sending, we can manage to get a good sound even low volume.


The configuration is very simple bass, middle, trebble

the range of sound is huge can easily have the AC / DC hard well through much of nirvana is filthy have a clear allucinant!!

I personally purchase is I do not regret this purchase so I can not find out when the manual if it is complete but the product is no longer manufactured so I think it does not interest many people


For the style I play fits me nikel (AC / DC, dportivo, its hard rock and not metal)

I connect over a fender telecaster lite ash and a gibson sg faded level pedal I do not use but I would suggest a volume pedal to move more easily from clean and saturbr />
may have sound trs adjustable lens with a good clear sound and sound baveu or fat on the distortion is what I love about this amp

This amp is great but I think if we use a lot of its clear it will be harder to use but personally I do not resell it fits me like a gand


It's been barely a year as I was and I am pleased (I was just 600 euros in cash converters for those that his Interesa TElement)

its a hard punch of the best marshall I would not say the best but at least in the top 10 I love this sound saturation makes exercise very well chalereux rock

Avand dessu I play a Marshall Valvestate 8080 (I always) I used to certain repeated or there is no alternative

if like me you have the opportunity to fall on it in this price range that I had fixed 600 800 (it's the price I saw on ebay on average) so I think it's a good buy Minten must have the means

if it would remake a remake I !!!!!!!!!!!!!!!!!

but I reppette I is not often clear sound is the use you make that matters

Marshall 2100 SL-X JCM900 Master Volume [1993-1999]
Good veiled the head Marshall jcm 900 sl-x 2100

- Head lamp while
- 100w (the heavy) or 50 W
- 2 HP 4 outputs 8 and 16 ohms
- Output "direct"
- Effects loop
- Presence, bass, middle, trebble, 2 volumes (switchable, useless my taste), and volume and preamp gain (basically a deuxiemme gain)

it lacks a little reverb, it's a shame, and my knobs a little crachottent


Not have to look you can find three sounds on this amp in 5 minutes, you just use the knobs.

- A fairly clean filthy limit crunchy super hot! (I plug my Shredmaster and ecstasy)
- A very pleasant crunch (with a good OD does!)
- A saturation type Hard 80 (Motley Crue, Wasp, Ozzy here I am!)

I use it plugged into a Peavey VK 412 cabinet (that is already in the butcher shop) next week pending the arrival of Marshall 1960 will give a! (I edit the post after his arrival)


I play on a Gibson Flying V with Seymour Duncan SH4, and I understand why combinason Gibson / Marshall is a classic, sounding a death.
I play Hard 80 ', the Heavy, the Trash and even the grunge of Alice In Chains and Soundgarden and I am conquered by this amp wonderful!
I sound pretty close to the head with Slash (relatively confused XD)
This is an amp very nervous, it's not lace, love has!


I have long wanted a very JCM800 and a 900, I was very fortunate to come upon it in the store, he begins parrait be rare. Jou have a lot of time on a Peavey VK112 VK412 +, whether there lights in the VK, I spend a cold and dry his big sound hot!
I can finally m'ammuser, I think investing in an MXR Zakk Wylde OD to swell even my sound.

Of course I would do this choice, why not even take me one day with 3 other speakers deuxiemme 1960 and make me a wall in my Piola, or in small pubs niois

Marshall 2100 SL-X JCM900 Master Volume [1993-1999]
So tube amp of 100 watts!

One channel but two footswitch selectable volumes, personally I only play on the A!

Level connectivity: guitar input, footswitch input, effects loop with level control, output and line out Compensated!

Besides a pentode mode / triode switch that allows the corny at 50 watts (off of mine)!

In short, it's simple and effective!


Setup is super simple, Presence, bass, middle, treble, and the two volumes called two gain settings and gain preamp!

We get easily a good sound and pushing the mediums, it is not aggressive screaming broken ear but more angry, in short a treat!

I personally think that the amp is very well balanced on all frequencies set to hand may be the presence that becomes really effective only after the race!


It is perfect for my style of music, that is the great big muscular rock that veers sometimes grungy metal with trends and quieter passages!

I play with a Gibson SG and a Fender Stratocaster, because I stick a Vox Wha, a Digitech Whammy, Small Clone Chorus Electro-Harmonix, an Ernie Ball volume pedal and a Korg DT-10 Tuner! The head responds very well to the effects of any kind!

You should also know that the game is top marmoset no effect!

The amp is very touch sensitive as they say, it responds well to pick attack and has good harmonics!

I get distorted sounds both bitter but with the body, depending on the amount of gain, it will very nice crunch to the good saturated fat which sends (nothing to be ashamed in front of a duplex, it has the same amount of gain is the only truly Hi-Gain amp brand)!

The bass is pretty without being too invasive, the mediums are very well spaced, it does not change the aggressive merdico bizarre and the treble is by a hair against harsh, but hey, this is typical of most Marshalls mordern that!

Otherwise, there is a way to adjust the silly to have the clean, the Clean and Crunch are also perhaps a little less charming than a JCM800 2203, because the beast is really made for saturax, but it is doing not bad in other areas!

Until then I passed her in the clear knob fiddling with my guitar volume, but now I use a volume pedal and it looks quite effective because the amp responds very well!

In short, it sounds about right and correct in all registers with honors great for large saturations much good punchy!

The amp goes well in the mix and it's a treat!


So I use it for two weeks, I already did a lot of repeats and I had the time to Retube (JJ EL34 in the power to blend personal and small to preamp), it sounds nickel chrome !

I like the side-channel, whereas before I had to finish instead of multichannel amps (2, 3 or 4 channels for some) and I realize it's pointless to have too many knobs, it limits distorts more than anything else!

I have owned a JCM800 2205, too old-school, aggressive and not really focused on the type of sound that I liked, it was too harsh and not flattering and that's never really clean or even saturated as it should I found (super aggressive media, acute invasive), one ENGL Fast Hand Motion (Limited Edition Ritchie Blackmore), not much bass, or body, reactions to the game against excellent (even better than the 800 which, was not bad at all), but amp too focused midrange not sharp with a grain shape, a bit too rigid though somewhere I would still like a lot (also ENGL is a brand that I always even if it is not really what I want), then I went through the box with a single front, then switch to nag too correct dual channel, hoping that would satisfy me orange, but not the fronts (for eh me) are not susceptible to attacks picks, insensitive to the type of scratch, not at all well defined (as it drools impossible) but against the big bass are sending (something that I was missing so far is also why I turned to the side) but hey, I was a little disgusted because of the large low group it sounded a little too soft, my bass player had even thought changed his mind because I'm invading its turf, in short, these amps really weird rectos!

And so there, back to basics with the SL-X and I've never been so enchanted! The saturation is perfect for me, is what to do and the amp responds well to all the same EQ knobs corrections even if it's not the finest, but hey that's fine personal, it's simple to resolve, we want more of a medium with a small lick of bass and treble plus a little back to create a sound a little more work, then hop boom that answers and it works (unlike the weird knobs and front sides of such 'eq of ENGL bland or even my old JCM800)!

Vala, if it again, this is the first time I am really happy with my sound and I do not think I'm over the head when whether it should change anything or not, and I realized account that the arms race was not used much always (I even had his eye on VHT to time to replace the front), I will take it one day and why not a 2203 or a small preamp oriented clean sounds to combine everything!

Vala vala!

Marshall 2100 SL-X JCM900 Master Volume [1993-1999]
All-tube amp head, no diode or as little of the JCM900 dual reverb!
The 2100 version is a 100w head, personally I own the 2500 which is the version 50 of the head!

The settings are very simple, this one setting, a 3band equalizer, two switchable master volume, gain adjustment and an adjustable volume of the preamp!
A switch hight / low backside the head, which allows some kind of power divided into two, convenient to home!

I put new, because the sound is exeptional, I would not go up to ten because we regret the existence of a second channel!


This head is single channel! To get a clear sound, you have to play the volume and tone on the guitar!
Marshall aggressive sound for a comsomé with SG, there is no better!

I put 8 because again, we regret the existence of another canal, after such a matter of taste!

It is not any time to have a pseudo second channel, the two fat master volume control that are switchable!


Moving from a clear sound a little crunchy with a lead of more aggressive by simply turning the knob gain!
The sound is very impressive! I put that head to the same height as the JCM800 in Jmp2203, the grain is at the rendezvous, the heat Equal!


I use this head for 1year!
I like the progressiveness of the gain, the dynamics of the amp, the only downside for me and the single channel, but there are people who apreciated this, then all the best marshall head are almost all single channel at the same time!

I already play a lot of amp marshall, peavey, laney and H & K, the JCM900 is doing more than well, it is even the best marshall head in my play! Heat, momentum, gain = D!
