For sale is a used 1978 Marshall JMP 2203 100 Watt Tube Guitar Head. This amp is in very good condition with typical dings and some wear in the Tolex. There have been some mods made to the amp. The box is a replacement. I personally like the white tolex. There has been a master volume added to the amp. The output transformer has been replaced with a New Sensor JMP 100 output transformer. It sounds amazing. The transformer is built to vintage specs with correct interleave ratios and lots of iron. The tubes have plenty of life left in them
