Killer sounding 1974 Marshall JMP 500 model 1987. Large box, printed circuit board. Make no mistake, the 50 watt 1987 circuit helped shape the sound of rock n roll guitar and I must say this example sounds phenomenal. Mostly original circuit less some replaced caps and a master volume mod. The master clicks on / off and is better suited left off as when it is engauged it drops the volume drastically. No back cover.

Year: 1974.

Model: JMP 50 1987

Serial: 6182F.

Condition: Overall in good to very good condition less some tolex / cab wear as well as some chassis wear. No back panel.

Modifications: Missing back panel, master volume mod, some replaced caps, otherwise original.

Comments: Killer sounding early 70s JMP 50 watt head.
