JCM 900 MK3 vs JCM900 SL-X

MARSHALLDUDE · 05-27-2009, 08:29 PM

Hi there! I nide a some help, what amp is more recomended for playing alternative rock,the mk3 or sl-x on jcm900?¿

American Viking · 05-28-2009, 06:49 PM

SL-X... all tube, can't go wrong. no one speaks very highly of the High Gain Dual Reverb models and the original High Gain Master Volume models have solid state diode clipping distortion.
I myself am not saying they are horrible but in comparison the SL-X is more favored.

LOL they aren't bad amps. It's a tube Marshall...well more of a sneaky hybrid actually which is why the marketplace puts a lower value on them than a JCM 800 or a JCM 2000. Plus 900's without EL 34 tubes can be quite harsh. We have one in the practice room (the bass player uses it!) and I tried it a few times. It was fine after I figured out how to dial in "my" sound, but once I did I didn't want to mess with it. It was rather brittle sounding and I had to try and warm it up.

My DSL OTOH I mess with constantly because it has so many fine tones and great distortion levels. It's 8 amps in one! On the other side of the spectrum, a JCM 800 is also a one trick pony but it's a GREAT trick; very warm sounding. Marshall realized the JCM 900's were a bit lacking (due to the clipping diodes no doubt; 1988 JCM 800's got them too and are to be avoided) and came up with the SLX. The extra TUBE gain section really warms up the 900's. My next two Marshalls will be an SLX and one of the 800's.

Rivers from Weezer used a SLX for touring.

I use a 4100 Dual Reverb and it suits alternative rock quite nicely. Key is to get an EQ pedal and keep the gain levels as low as possible. Otherwise things get harsh on the clean or inarticulate on the gain channel.

dmnall · 05-29-2009, 12:04 PM

Well I have a MK3 2100 and it sounds great.. Mine has EL34s and I did shape the tone with an mxr 108 *10 band EQ* and I am running a modded boss sd1 in front of it, but I have the Gain Sensitivity down to 16 - 18. My 900 sounds just as good, if not better then an 800. I know when I max the gain sensitivity, the amp starts sounding like an ice pick with too much treble, but the way it sounds with it down just a nice warm full tone... Great for Black Metal and Death metal!

Cheers,
Charlie

MARSHALLDUDE · 05-29-2009, 05:09 PM

THANKS FOR ALL UR HELP GUYS,I went to the store and found only one MARK3 whit EL34S tubes and sounds pretty good for my sound, I could not find any SLX BUT To be sincere MARK3 has this powerful GRAWL! i tested the amp in several ways but the sound is better when you put de master volume to full 10 and use the gain has the master volume and is just what i was looking for.. thanks again!

steelhorse · 05-29-2009, 05:12 PM

tear it up bro!

dmnall · 05-30-2009, 01:54 AM

Marshalldude,
Enjoy the MK3, it is a great amp.. Once dialed in it is great. The only guitar that I own that does not sound as good as my other guitars is my Rhoads pro but that will change when I get my 2 emg 81 pick ups installed in place of the stock Jackson Active pickups!

Cheers,
Charlie

rockinr0ll · 05-30-2009, 04:57 AM

SLX for the win!

....read farther down....

If you found what you want then who cares what we say.

Good luck!

psphill27 · 05-30-2009, 09:16 AM

Great purchase. I have a Mk3 30 watt head and absolutely love it. Once you get it dialed in right, and have the right effects setup in front of it, I think it will hang with anything. I have a DSL 50, VM, and I love my JCM 900 as much as both of them. They're all good in their own way.

Bottom line: it's a Marshall and it will rock.

RobS · 05-31-2009, 05:14 AM

I agree with DMNall, I keep the gain between 14 -16 and found it sounds great there, especdially when cranked. Higher gain 16-20 is good at lower volume but at higher volume gets a bit harsh. Mines a 900 4100DR by the way.

LesPaulopolis · 06-01-2009, 12:16 PM

Glad to see some other happy 4100 users!

Are you guys using the lead channel as a 'soloing only' channel, or are you like me and are using it for your crunchy chords, then boosting it for solos? I've been thinking about getting a pedal to use for crunch tones on the clean channel and using channel B for ripping feebacky solos only. Anyone have success doing this? Other suggestions for great tone?

dmnall · 06-07-2009, 06:09 PM

Well I want to add something that I can now say, the SL-X I thought was supposed to have more gain then the MK3 and I honestly cannot tell the difference.. I picked up a SLX 2100 for my co-worker today and I can say that I cannot tell the difference because both have the same amount of gain except the SLX was modded with dagnall transformers and has EL34s in it the same as my MK3... So how come they sound the same to me??

Some updates, the SL-X does have a little more gain, however, it does not sound as large and full as my mk3.. So in my book the SL-X is a good amp but the MK3 2100 is a better sounding amp, sounding better then even a JCM 800 in my opinion...

Cheers,
Charlie

steelhorse · 06-07-2009, 06:56 PM

Yep everyone has an opinion and of course you're entitled.

One thing I want to correct, the SLX should not have been modded with Dagnall's they came stock with them at least the 3 or 4 I've ever owned had them.

I also had to bias each one to get that real Marshall crunch and roar because their former owners either had them too hot or too cold.

The most recent I installed a high gain set of JJ E-34L's. Sounded like a souped up Hemi.

Steelhorse,
Nothing wrong with the amp, just sounded a little thing. I thought the Dagnalls were not stock because the MK3 I have here does not have anything on there to say what came stock.. I know that I even tried to add the MXR 108 to it and it sounded better but not as full as my mk3.. My friend actually wants my mk3 and I am just not sure if it would be worth to trade since the MK3 had more fuller sound.. Plus the Amp was modded with EL34s *EH* while my mk3 has Winged C *SED* EL34s??

Would you say trade the amp and add different tubes???

Cheers,
Charlie

steelhorse · 06-07-2009, 11:00 PM

It sounded thin because either the tubes are shot, it's biased wrong or both imo.

The SLX's I've owned are total beasts and can whip many amps they are that monstrous imo, BUT they have to be set up properly.

Don't expect a jet to run on unleaded know what I'm saying?

I never used pedals with the last SLX-2100 I had once I re-tubed and re-biased with E-34L's.

Notice I said E-34L's not EL-34's. Huge difference. The E34's have a very effective and tight bottom end that gives it that fat crunch.

The SLX's I have owned and or seen in my years have all had Dagnall's if they were stock. I saw 1 with Mercury's that was modded.

Listen if you love your amp then by all means keep it, either way you'll be fine.

dmnall · 06-08-2009, 12:27 AM

Steelhorse,
Here is the thing, I through my mxr 108 and threw my modded sd1 and damn this amp was really impressive very booming bottom end. I am going to play with it tomorrow more and after tonights run the SL-X is proving to be a beast so to speak. I do love my MK3 but the SL-X is becoming a better sounding amp and from what I can tell, they both have their strong points. At lower volumes, lowering the gain down and slamming the front end of the slx is getting the huge tone.

Also can the fact that the Pre-Amp Tubes are still the original Marshall Tubes be the issue as well??

Thank you,
Charlie

steelhorse · 06-08-2009, 12:44 AM

Considering the amp is as old as it is, the answer is most definitely the pre amp tubes are affecting the tone.

The last SLX I bought the pre's were sovtek's and were reportedly 7-8 years old. Still sounded ok but really lacked the life & tone imo.

I changed all the tubes, cleaned the sockets, re-biased and damn that thing slammed!

Your driver and tone stacks are in the pre's.

dmnall · 06-08-2009, 01:03 AM

Hey Steelhorse where are you located??? I am asking because I am seriously thinking of keeping this beast and having the tubes changed. This SLX is 94 and on 6-4-2008 the guy who I picked it up had the el34s installed in Indiana by a shop. But I got the amp for my friend with a 4x10 cab for $ 700 and my friend wants my mk3 and I am seriously thinking of doing the swap since This amp just needs at least preamp tubes which will probably make it sound a hell of a lot better.. How hard is it to Bias the Tubes?? Also the power tubes came from Tubedepot. But on Average is the bias numbers on the tubes say 32 according to the Tubedepot...

So should all the tubes be replaced???

Cheers,
Charlie

Yeah I read that Grider.. But the 2100 sl-x with el34s sounds really close *well the one I have did with the EH EL34s and Marshall ECC83s*... Right now I am having it gone through with new JJ Preamp Tubes and JJ E34Ls per Steelheads recommendation and I have a feelling that this thing is going to be a beast with out an o/d pedal and the MXR 10 band in it!

DMNALL :i think your goin to regret this one,I keep the mkIII my opinion...

steelhorse · 06-13-2009, 05:14 PM

nah you won't regret it, the SLX is a great amp. for alternative the MKIII is definitely more suitable, for metal, SLX all the way baby!

5er driver · 06-14-2009, 02:09 AM

steelhorse · 06-14-2009, 02:47 AM

oh yeah

jcmjmp · 06-14-2009, 08:45 AM

The nice thing about the SLX is that the guitar signal hits a tube VS an opamp. If you want to push the front end of the SLX, you'll get a smoother sound vs overdriving an opamp.

Marshalldude,
I dont think so yet. I got the slx to sound a lot better by boosting the front end with the crappy tubes it had while turning the gain on the down... That slx screamed more tone then I could pull out of the MK3..

Now with the tube recommendation that steelhorse let me know... The SL-X is going to not need the boosting and will not need the mxr 10 band in the eq... Since I play metal, death and black metal.. Why not have a higher gain amp with out the eq and the boss sd1 pedal..

The amp was getting really muddy sounding and maxed was oversaturated with gain that it sounded like crap. On the Mk3, it was close to being at SL-X gain on 18.. So I prefer the SL-X and I should have it tomorrow! So it will be a test with my RR pro guitar, Baritone, LPS and Strat.... I cannot wait to get some better metal tones out of this amp with new jj ecc83s and jj e34l tubes!
