For sale is a used 1979 Marshall JMP 2204 Master Model Mk2 Lead 50-Watt Guitar Amp 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 to the tolex. With the obvious exception to the tubes, everything is original on the head with the exception to the cable holding pieces on the back and we ordered a replacement logo from Marshall because the original was missing. The tubes have plenty of life left in them.
