What do you guys like as a high gain JCM800?

I love Greenies for classic rock and 80's hair metal(Zep, AC/DC, Priest, etc...).

But if you are aiming for a tighter, higher gain tone than that, a speaker change may do wonders.
Could save you a ton of cash too.

Someone else may chime in if this is something you are willing to entertain.
My speaker/cab experiences are rather limited so I will kindly yield to someone else to walk you down that slippery slope lol.

My cab originally had V30s in it (the Mesa ones). I found them a little too harsh with the Mark IV. They sounded really good with the Friedman though. I found that Greenbacks have a more balanced tone than the V30, but maybe not quite as tight.
 
The Helios is nice, I had one for a few years and mostly liked it. But it does have a few WTF design choices. No grid stopper on V1, so it picks up radio stations quite easily. Half of one of the triodes is also unused, so there's a free gain stage there... so why Bogner chose to use clipping diodes instead of a tube gain stage is beyond me. I like diode clipping as much as the next guy, but a tube gain stage does sound better. A few other more technical things going on. For the most part, it sounds good though.
 
Again, to me, they seem more compressed and less chewy than my actual vintage marshalls.

Appreciate your whole response, but I just wanted to focus on this little detail for now. I've never played a vintage Marshall, so is it normal for them to have a putty or chewy feel to them? I'm guessing that's what my Friedman is attempting? The DSL100 I owned for a long time, it definitely did not feel very chewy to me.
 
OP, I've been down this road and wasted a lot of money chasing "The Marshall Tone" without buying a Marshall.

If you want Marshall tone, get a Marshall. It really is that simple.

By your description, and if you refuse to use a boost/od pedal, a JVM or modded JCM/JMP is what you're after.
But even those can greatly benefit from having some sort of dirt out front. Dont cut yourself off at the knees.
Some sort of dirt/boost in front of any amp is just plain fun! 😁

Marshalls have been around for decades.
Any given brand can have issues and/or duds. But should something go wrong with, say a JVM or JCM/JMP, they've been around for so long, any amp tech worth his/her salt should have you fixed up rather quickly.

Appreciate this, and I agree that I should learn from others. I'm leaning towards just going back to Marshall in some form. I like to keep my SD-1 around just for fun, but it's not really my main sound.

Yes and no. It's a sliding scale. A hot-rodded Marshall, if done right, will have a tight low-end that tracks fast. But it will still have a pleasant give when you dig in on the initial attack. When I think of "chewy", I think of a low-mid emphasis with a bit of compression—Bogner. Friedmans... I can't say I've played any that wowed me. They are on the more tame end of the spectrum, IMO. And I gravitate toward angrier, more aggressive, more pissed off tones. And a DSL isn't really in the same territory as a hot-rodded 1959 or 2203/2204.

No problem buddy....

Most importantly, what are YOU playing? I typically resort to the Dokken, Ozzy, Whitesnake, Ratt, Journey, STYX, Van Halen, King Diamond etc... Bottom line, a lot of big, open chords and double stops...

Even newerish Marshalls IE DSL's (Actually a decent amp board issues aside) 1987X, Super Lead etc still have some of that chewiness compared to a tight, more compressed amp like a 5150, SLO, etc.

I'd bet you the DSL was biasd on the side of caution from the factory IE: Colder Bias, less chewy.. a tech can get more into that but typically, the chewier amps I've owned were always biasd on the hotter side. Modded Marshalls are a terrible example as I have Lee Jackson modded 800's that sound woofy and then a JMP he had a hand in that is absolutely Van Halen 1 in a box.

I'll stick with my original answer until I hear your music tastes.... When I was gigging alot, playing professionally a concern I always had was if my main amp goes down, 2 is 1 and 1 is none... I loved that the Quick Rod's were pretty available back then and I could likely jump onto a marketplace, guitar center etc and find one because they all were pretty close. Were some I owned better? Sure... Always preferred the older, pre 4th tube circuits if memory serves me, mine now is an 06'. When I thinned the heard, all the later ones were gone. Personal preferences but at least that would give you a good starting point.

Man, I’m glad I don’t know what I don’t know. I’d be pissed off all of my amps! 😊
