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?
