DESCRIPTION: For sale is my 75' Marshall JMP 1987. My asking price is $1500.00. This is a nonmaster vol. head, but a master vol. mod has been added to one of the rear speaker outs. When the master vol mod is on 10 it is completely out of circuit. Please keep in mind i used my cell phone to record this video. The head is set at a volume no louder then a loud conversation. So you know the sound isnt going to be the best. I just wanted to put something out so your'll able to get an idea.
