1984 JCM 800 100W
Yup. That's pretty much a 50 or 100 watt JMP with a facelift (Usually w/ EL 34's). I prefer the older face...They're out there.
800's sound great w/ 6550's.
The good Marshalls are really just the Fender Bassman's little brothers. But little brother went to the gym more.
I had a great Bandmaster, but I kept blowing it up, awww...Still, a great first amp, even if I did miss the thrill of owning a Peavy.
