A super nice early Marshall JMP-50 Plexi amp showed up in the workshop......our very first experience with a Marshall amp.....and provided a great opportunity to thoroughly dissect it, compare its circuit to that of the Fender 5F6A Bassman, and then evaluate its tone through both a 3 x 15" speaker cabinet and a Leslie speaker. Viewers have been clamoring for a video featuring a Marshall amp......so here it is, and it's a DANDY !!!
