    Title says it all. Corporate probably figures just buy the JCM 800 reissue, but those JMP models were sex in a box. Wouldn't be hard. Use a Plexi box, JCM innards with a changed capacitor here, resistor there. Easy peasy. Maybe even a limited JMP Studio Classic. My credit card is ready and standing by.

    Yes they did re-issue 2203 2204 but 20 watt now instead.
    Demand for smaller amps and lower costs is what drove that.

    Me three. I've always preferred the master volume JMP 2203 / 2204 design compared to the JCM 800.

    I favor the JMP era versions as well. And the earliest JCM versions were pretty much the same amp, but I draw the line when they redesigned the board to incorporate the controls on the PC board and the input jacks went to horizontal. At that point the cheapening is more than I'm willing to put up with.

    Id be all over a JMP2204X. Pretty dumb cause I have a perfectly good 2204 clone. Really like to see a SC20 in JMP dress. Would probably bite on that too.

    I think it would be great if they continued the trend of the low watt reissues. Give me 20watt JMPs and JTMs in correct head cab styling.

    jmp 2203/4 also. To me the 78's sounded thicker,richer and less harsh than the 800's.Look better too imo.

    One of the keys to the great sounding 2204 50 watt JMP Master volume amps was that the really good sounding ones were only running I think 440 Volts and the harder sounding ones were running upwards of 495 Volts.

    It's the caps. In 1981 they went to the red box-shaped caps, and they don't sound as good, IMO. Now, that is relative, since JCM 800's do sound awesome. But the tone began to change as they ran out of Mullard mustard caps. First they went to the green caps (77-78), which still sounded amazing, then they switched to white caps (78-80), also still sounded great, then the red caps. The red caps sound slightly harsher, to my ears at least. Not quite as cool of a tone. I sold the 1981 JMP 50-watt I owned, as it didn't measure up to the 1977 JMP 50-watt that I will never willingly sell. That amp is a rare one, with a full compliment of mustard caps.

    I know some guys will disagree, but I always say that everyone likes what they like, so it is really a matter of taste, when it is all said and done.

    And, to be fair, an early 80's JCM 800 is on my acquisition list, if you know what I mean, lol. And I like the looks of both styles. It's all relative, it's splitting hairs, to be honest. They are all badass Marshalls.

    No no no! Lol. Late 70’s jmp mv had a lower plate voltage. A lot less harsh than the jcm 800. Imo from all that I’ve heard.
