I have a Marshall TSL 100 JCM 2000 head with a bad 6 pin footswitch connector. All I have to do is get to it so I can resolder the terminals. After taking off the back plate, I just can't figure out how to get the head apart so I can reach the footswitch connector. Can anyone out there provide some clues? Maybe a few step by step desciptions or a few pics??? Any help would be appreciated.
