For sale is a used 1976 Marshall JMP 2204 50 Watt Tube Guitar Head. If you are looking at this listing, than you already know this is one of the greatest amps that Marshall has ever made. Hands down my favorite, as it delivers that raw and rude tone you would expect from a late 70's era Marshall. This amp is in good condition with normal wear that would expect from a 42 year old amp. There is wear in the tolex and it looks to have been painted over in some spots. With the obvious exception to the tubes, everything is original on the head. The tubes have plenty of life left in them.
