Can the JCM800 / JMP 2203 do modern metal?

I own a JEL mod 2203 JMP.

Currently have tried boosting with an SD1 and OD808.
V30 speakers

Guitar has rather high output pickups

It sounds good don't get me wrong.

Wouldn't say it's as modern as my old 2ch dual rect.

Any tips on really taking these into modern high gain territory?

My definition of modern is like dual rectifier, 5150/6505, uberschall etc.

Or am I trying to make the amp do something it really can't?
Yes it will just try a 10 band eq ,deadweld duality ,fortin 33, any ts9 or od808, maxon,Friedman boost etc. just experiment with various pedals to shape your guitar tone
 
Not to derail the thread or anything, but it's sorta on topic. How big are the tonal differences between a JTM 2203 & JCM 2203. I know there was variances in tone just from amp to amp even in the same production year. Does a JTM have more of a 70's vibe to it and and JCM is more 80's90's?

That could play a factor in if it can stretch into modern metal. I could see where an 80's/90's vibe type amp with a different gain/tone structure and feel having an easier time doing it. Maybe it could be more about finding the individual amp that's better adept than looking at the 2203 model as a whole.
 
The later ones are said to be a bit brighter and from my albeit limited experience I can agree with that. I seem to remember that the circuit is more or less the same from the JMP to the JCM era but that there is a difference in the voltages. The dudes that know amps for real will chime in, I´m sure.
 
In short...........YES..............:yes:

The VFE standout is very good but the Maxon ST9 Pro+ is absolutely killer into a stock 2203 or modded 2203. I got a Maxon ST9 after watching Killtertones video and it's crazy good into my Splawn modded 79 2203 with stock levels of gain on the 2203. The pedal drives the shit out of the 2203 and the ability to adjust the mids and highs really add to how aggressive you want it.

Here's Killtertones totally stock 2203 verus a Dual Recto and the Marshall keeps up with the Recto IMHO. He is using SD Black Winter pickups in the video.

I also picked up a Maxon ST9 Pro+ after watching Jason’s video and I’m so glad I did. It does sound absolutely killer. I’d say my KSR Eros can get slightly more modern, but the Maxon ST9 Pro+ is amazing. My son is helping to pay his way through college in a classic rock cover band and we tried the Maxon ST9 Pro+ driving the front of a Fender Vibroluxe Reverb reissue and holy crap! The SRV tones that jumped out of that amp when he played Voodoo Child Slight Return blew my mind with how great it sounds!

Despite guys saying they’re the same on paper, I found the late ‘70’s JMP2203/4’s to have a richer, warmer, juicier tone with more growl, especially in the mids. The JCM800’s IME tend to sound brighter, tighter, punchier, smoother mids, not brittle, but more in that direction of the spectrum. They would be a bit closer on the spectrum toward modern, but still wouldn’t be what I’d reach for if that’s what I was going for
 
I must report I did not like my 78 2203 for modern metal in any way . But blended with another amp it was spectacular . Alone is a no go . I mean you could make it work but you’re just doing a bunch shit to make it sound like a modern amp already in the arsenal . But blended its it’s a great asset
 
I think it's kind of a subjective question, but the answer is objectively yes (IMO 🤣), but with the caveat that it might take more work and fiddling ...It also might be worth it! Agree 100% with those suggesting double boost + EQ in loop to get there.

I recently got the OD808x and like Eric Rutan I think you'll give up your original if you're into more modern tones.
