Need info on Marshall JMP combos

[ToneLounge]

Specifically 2104 50w MV or similar. Anyone playing these?

Thanks,
B

I've got one at the moment and owned about three in the last 3 years. I keeped the best one. Although I must admit I'm not sure about that model number since Marshall DIDN'T put model numbers on these is the seventies. Mine is a 2X12 combo that is a 50w master volume head turned upside down with knobs facing up (and backwards).

What did you want to know?

Brian and Bruce, I can consult Doyle's book when I get home later (if that helps). I can back Bruce, when I say that the JCM combos that I've played sound very good - that is, they respond like a MV Marshall. Check the pwr section. In the late 70's/early 80's, the American models typically shipped w/ 6550's and the British versions had the EL34 tubes.

Well anyway Brian, I know these amps very well so ask away...
