    Hey Guys, Can anyone tell me what year they stopped making the original JMP models and began making the JCM 800 2203 models? Was the first year of the JCM 800s 1983? I may be wrong but didn't they stop the JMP builds and then start the JCM 800 builds or did they overlap in build years? Am I making sense?

    I keep hearing about how these two models (Late JMP and early JCM 800s) were basically the same amp on the inside. I also heard that at that time Marshall was about to go bankrupt so they scrambled to build the JCM 800s and some early models they used leftover parts from the late JMPs. Anybody?

    They ran parallel in some markets for a few years. I think 800 came in -81... I've e seen Swedish market jmp's as late as -84
    I'm sure someone else will come in with more details

    There was an Anniversary JCM800 in 1982 so I think you're right, the first units were 1981. I have a 1982 regular 4010.

    I had a 1980 JMP 2203 and currently, I have a 1976 2203...first year of production with the early 70's JMP box!

    I think 1981 was the first year for JCM800's.

    1981' JCM-800


    There was some overlap.
    Technically first year for 800's was 1981'
    But i have seen a 1983 JMP 2203 complete with old JMP style headshell.
    My guess is they had some straglers to get out the door.

    Here is the answer I got back from Marshall. Looks like the JCM800 was introduced in 1981 but didn't start shipping right away. The 2203 and 2204 would have been the same versions as the JMP until about 1984 when the PCB circuits changed. I was just curious about how close the JMP and JCM were in the early days as I have a 1983 JCM800.

    So would a 79 jmp 2204 be about the same thing as an 81 800 2204?

    Yes! All the inside components are identical. The only thing different is the shell.

    I have a JCM800 2203 from April 1981.
    Mine doesn't have the USA sticker/6550 tubes/circuit. It just has a 'sticker' (no country designation) and stock EL34 tubes/circuit. So I don't know if it was shipped over the USA 'en masse', or the buyer brought it over, or if it was shipped by Marshall specially or what. I have no idea. It did however have a human finger inside the chassis from a factory accident I assume.

    I think all the early JCM800's shipped with a human finger in the chassis. Marshall started shipping them again with fingers in the late 2000's but they were Russian and Chinese fingers which just did not have the Mojo of the early British fingers. Two in every Ten amps shipped with thumbs, These were said to be the ultimate.

    I love my 2204 and have a 1977 JMP 2203 that is a hack job but sounds good. I would still like to have that 81-2203 on your table there, it looks very nice !
