1972 Marshall – JMP 50 – 50 Watt, Model 1987 – ID 5240

Post-Plexi era at its best! This 1972 Marshall JMP 50 (Model 1987, Big Box) is exemplary for the sound of the early 70s - powerful, biting and yet transparent.
Exactly the tone with which Michael Schenker (UFO) and his Gibson Flying shaped the rock sound of this era.
Freshly serviced, technically top and in really good condition - a piece of amplifier history that is ready for immediate use.
The faceplate and the impedance rotary switch have been replaced.
Master volume with control on the rear panel.
The housing comes from a 100 watt top from this period.
