Thinking about getting one of these. I play in a Classic Rock Cover band (Johnny Cash to Metallica).
I currently use a Marshall JCM800 channel switcher.
I usually only use the gain channel and ajdust my guitar volume knob for clean tones.

Is the JCM900 SL-X a good amp for classic rock?

Not sure about that model - but my JCM 900 (4502) 50 watt 2x12 combo served me well gigging for 19 years - great amp but I liked it best cranking the rhythm channel. We played a wide variety from Allman Brothers to Jimi and Pink Floyd, AC/DC, Janis, ZZ Top, Stones, etc. I plugged straight in using Gibsons and a Fender.

I heard Fogerty at one point was using a couple JCM900 heads. He is a tone king...

I think the JCM 900's are under-rated IMO.

It's a modded JCM 800 and shouldn't be associated with the diode clipping 900 series. The only one worth buying is the SL-X 2100 with EL34's, but it's very picky when it comes to speaker choice. Loads of clarity, great for old school shred.

Can I turn the gain down and get standard JCM800 classic rock tones?

I'd say so. It's a very versatile amp that can go from smooth jazz to modern beard music if you're not careful. Cleans up nicely with a guitar volume knob adjustment.

I'm using:
JCM 900 SL-X 2100 w/ MV at ~4
[[100 watt][90s Siemens EL34s]]
16 ohm Marshall 1960a 4x12 w/ Eminence Lady Lucks
[[Cheap speakers stolen from an Epi So-Cal I sent to eBay]]
Jackson Soloist SL1
[[Dimarzio PAF Pro Bridge]]

No pedals (other than a Hardwire DL-8 Delay in FX loop), guitar is plugged straight in. No post-EQs or Ableton magic of sorts, just a Sennheiser guitar mic into a Mackie Onyx w/ firewire card.

I'm too poor for a Super Lead, but I think my eBay rig does the job. Owning a plexi is like owning a pet elephant when it comes to practicality. Master volume control sure is nice.

Honestly it shouldn't even have jcm900 written on it. I can't stand 900's, but this is a whole different beast. Tons of gain on tap and really ballsy.

I need a backup amp for my JCM800. I don't really care for my Mesa F-50 anymore.
I'm thinking the SLX or a DSL.
I mentioned the SLX because I'm going to look at one tomorrow.

Thanks for all the comments.

No true clean channel on the SL-X, correct? The DSL has a dedicated clean channel. I kind of assume since it's going to be a backup to your 800 that you'd prefer the SL-X(?) I guess it depends on what you need, but both heads are usually available for a bargain.

As I do more research I'm starting to lean toward the DSL. I like having a clean channel because of the variety of music our band plays.
My JCM800 is a two channel.

Ah, gotcha. I don't know why I assumed it was the single channel variety. Yeah, if you need it to effectively serve as a backup, I'd get the one with two channels as well.

If variety is what you want go for the DSL. My only problem with 900s (excluding the SL-X) and 2000s is that they're a jack of all trades, master of none. The same can apply to an un-modded 800.

I'm currently using an un-modded JCM800 and I'm very happy with it. I'm thinking that means I'll probably be happy with a DSL.

I have a DSL50 and an SLX 100 watt both available near me.
I thinking I'm going to buy one of them tomorrow but the more I research the more I'm liking the two channels on the DSL.

I just got a SL-X in the mail today and I am completely floored. I got it on a trade that initially I didn't have high hopes on. I am so in love with this thing right now that it has me considering selling off all of my stomp boxes. It doesn't do clean for **** but the distortion is so tight. I'll probably get an ab switch to go between this and another amp for clean. I have owned a JCM800 combo and this thing eats it for breakfast!

That amp was a horrible mess. The JCM800 Channel switchers own them, hard. Stick with what you have.
It's a very picky amp. I just got lucky and happened to combine my EL34 SLX with mysterious Eminence speakers to make a poor man's plexi.
