Name That Amp

JCM800 2204 is also obsolete....
Not really everybody still copies it...pretty much the basis of all modern "high gain" amps.
They are all pretty much a Fender bassman with a gain stage(s) added.
Not much has changed.

I mean there was JCM 900 with SS input stage and diode clipping....
that was about the most creative it would get.
The few amps that were not modded bassman amps...not very many.
 
Where Marshall's fall short is the mid-range 25K mid pot same as the Bassman 5F6A.
The Hendrix and EVH amps were modified to 50K mid pot Dumble went 250K at 12 o'clock position killer.
My 1959 Fender Concert amp has the fattest mid range with no mid pot just 250k treble and 250k bass 500k volume less is more.

JCM 2000 sounded better than 800 or 900 to me. It's the only one I would consider.

My very first Marshall was a JTM30. Sounded great but had a nasty habit of overheating.

Used an SWR bass rig for some gigs in the 90s when I was working as a hired gun.
Good sounding head; it had decent preamp drive tone, plus a compressor and an exciter built in.
Nice EQ arrangement: bass & treble knobs plus a 4-band graphic where you could tune the center frequency of each band.

It looked just like this pic so I assume it was an SM-400.
