I've been very happy with my Recto, but there's always more to be had. In midst of applying for jobs, I'd somehow end up scouring the instrument section of craigslist. How or why I was on craigslist is a mystery, but it paid off.

I stumbled across an awesome deal on a VERY underrated and fairly unknown Marshall... the Marshall JCM900 SL-X. It's a hand-wired, hot-rodded Marshall JCM900. This amp is an absolute beast! I was never that big of a fan of most of the JCM's, but the SL-X really blew me away. I had an idea of what it would sound like, but was totally wrong when I played it. I was close to picking up a 70's vintage Marshall cab with the checkered grill cloth, but my girlfriend would have killed me if I came home with more than what I intended on buying.

Enough talking. I got home late last night and have been at work since 6 AM... time to go play the amp. Enjoy the pics.

The guy I bought it from was the original owner and your typical Gibson/Marshall kind of guy. He kept telling me there's no need for an OD with this amp, but I was a little skeptical. My Recto sounds great alone, but really needs an OD to tighten up the low end. I played the amp last night before leaving his place and was shocked to find out he was right. The SL-X sounds amazing on its own and tight as hell without an OD in front of it.

You should knock him out with his Boss processor, take the amp, and play it the way it was meant to be.

Congrats.

never played one myself tho.
I wondered why the frisbee was getting bigger, then it hit me.

I have an SL-X and i agree with exactly what your saying, its a beatiful amp.

What do you use as OD with it?

Ive used a Luther Drive and an '84 TS9

Thanks! The SL-X runs under the radar, yet is easily one of the best amps Marshall has released over the past 20 years. No idea why it's so underrated and unheard of.

Quote by 311ZOSOVHJH
Congrats. I've heard good things about this amp too? So are you keeping the Recto? Maybe sell that to fund a killer cab?

There's not a whole lot on this amp. It deserves to be on the forefront for Marshall. I was set on keeping the Recto, but after playing the SL-X I'm on the fence about the Recto. It's really that good.

I had a feeling you'd know of the SL-X. They're hard to come by. Everyone who has one is holding onto it. Seems to be a hidden treasure by Marshall. I'll be hanging onto it for quite a while.

SL-X's are good, they removed all those bs opamps and clipping diodes at the front and added a tube instead. They still have a couple of opamps in there but they are further down the path. The input socket connects directly to a valve so you can drive the hell out of it and it still sounds good.

Like I mentioned before, I probably won't even throw an OD in front of the SL-X. As crazy as it sounds, I see no point.

Quote by WtrPlyr
The SL-X is hand wired? That's cool.

Anyways, HNAD


I opened it up last night before buying. Everything is immaculate.

You sure can! If you happen to have more info on the amp, please PM or provide me with links or whatever. I had a hard time finding much on the SL-X. I'd really appreciate it.

The price range is all over the place. If you're lucky, you can find them around $350 to $600. The used section of Guitar Center brings up several ranging from $700 to $1300.

I was originally going to buy that guys SL-X. He was going to let me take it for $300, but turned out he wasn't legit.

Will do. I've got a few OD's I'll try out.


For those that are interested, here's some info I dug up.

"Marshall have specialised in the production of valve amplification since 1962.

The unique tone and playing response of the valve has formed the cornerstone of the Marshall “Sound of Rock”, which we have modified over the years to cope with the changing demands of the evolving guitar player.

The JCM 900 models split into two distinct product ranges, the Master Volume SL-X and the Dual Reverb. Though they share common ancestry and have similar rear panel functions their applications are quite different.

HI GAIN MASTER VOLUME SL-X

The latest innovation from our valve designers involves the use of an extra ECC83 pre-amp valve in the gain stage of the Master Volume SL-X models.
This gives a gain soaked front end that is the most extreme yet produced by Marshall and is controlled by twin gain controls, the first (item 2), from 0-10, the second (item 3), from 10-20! Combinations of these two controls can take you from classic Marshall crunch in lower positions, to pure overdriven outrage on maximum. It is well worth experimenting with these twin gains in conjunction with the tone network (items 6-9) to really get to know the full capability of your new SL-X head.

The twin Master Volumes (items 4 & 5) are another unique feature of the SL-X amp giving you two footswitchable output volume levels, ideal for rhythm to solo switching. Although a clean sound is available, this amp was designed for the uncompromising high gain player who demands a no compromise sound."

* Twin gain controls from 0 to 10 and 10 to 20.
* Twin footswitchable master volumes (A) and (B) for rhythm to solo volume switching.
* Equalization controls for Treble, Middle, Bass, and Presence.
* Effects loop with sensitivity control.
* Direct and recording compensated line ouputs.
* Impedance selection switching.
* Twin loudspeaker ouputs.
* High/low power switching (pentode to triode).
* Valve failure LED's.
* Entirely wired and assembled by hand.
* Made in England.

Asking about Recto because you deserve a better cab than that Peavey. Just thinking GF may not care as much if you use funds from Recto and old Cab to buy a better cab - like a Mills or Splawn or even a Marshall or Mesa cab.

He was flakey and dishonest. The day after I told him I'd stop by to try the amp out and buy he didn't answer my calls/emails/texts and deleted every FS posting he had. Smells fishy to me, so I backed off after the 2nd day.

I was actually extremely close to buying a new Mesa 2x12 Recto cab for an amazing price a few weeks back, but wasn't willing to drive 3 hours to get it. The seller wasn't willing to drive more than 10 minutes from his house.

The JSX cab sounds surprisingly good with both amps. I've used the Recto/JSX combo live and in the studio with my last band and couldn't complain. The guy I bought the SL-X from had a ton of gear. I played it through his JCM900 cab last night, which is loaded with G12T75's. Sounded great. The JSX doesn't really lack in any department, it has a very balanced speaker response without sounding too woofy or harsh. I may replace the cab down the road, but not really thinking about it right now.

If and when I do, there's a good chance it'll be a Mills or Mesa. Can't go wrong either way.

Great amps. The SL-X was made to compete with the Rectos back in the day, except they were the old two-channel models.

I've always wanted an SL-X too, they occasionally pop up on my Craigslist for great prices but I never have money.

I know how you feel. I was very disappointed when I missed out on the first SL-X I came across. A day or two later I stumbled across another and immediately jumped on it. Just wait till I get a chance to record some clips, you'll really be itching for one again.

Thanks for the info! Didn't know the SL-X was meant to rival the Recto. It sure as hell can keep up with my Triple. Hopefully the next time you come across one you'll have some extra money. It's truly a hidden treasure of Marshall's. Can't say I've ever been this impressed with a Marshall.

Thanks! Found that a few hours ago. Contains a lot of useful information and specs.

The SL-X slays. Why Marshall only produced these for 2-3 years is beyond me.
