Hey Gang, Been a long time since I posted in here. I just put an out of state JCM 800 2203X on layaway and I had some questions. The one I have on hold was made in 2007. How are the effects loops in these? Have they been redesigned over the years or are they the same loop from start to present? I'm just trying to prepare myself. If anyone has info to other design changes that would be great to hear about! I hope that with a reissue it's one of those things where is not had a lot of revisions but you just never know these days. Also, Has anyone replaced a Marshall effects loop with a Metropoulis zero loss effects loop? If so did the inputs line up exactly with the existing send and return jacks on the amp? Thanks in advance!
