Here is a vintage 1974 Marshall JMP Lead Mk II Model 1987 50W electric guitar amplifier head. This particular example, serial number 4505F, is in very good original condition! This early printed circuit board (PCB) version is every bit as powerful as its Plexi predecessor, and represents incredible bang-for-you-buck! Recently serviced, this amp is both studio-ready and a great choice for live performance.
Serial Number: 4505F
Inspection Date: 6-5-78 (June 05, 1974)
Transformer Codes: 1202 — 134, 784 — 139
The original black levant tolex is in excellent shape with only a few minor scuffs and a couple insignificant marks. The front metal panel is crisp and very clean with little evidence of wear or use.
This amp is highly musical, produces incredibly powerful overdrive, and instantly generates that tone you’ve been trying to emulate with other amps. This amp looks and sounds great. With the same 6-knob/4-input arrangement as the classic 50w Plexi, the channels canbe jumped to achieve an unbelievably saturated distortion.
Recommended for collectors and players alike, this amp is in very crisp cosmetic condition, and happens to sound every bit as good as it looks! Rarely rented by the cartage company that owned it previously, the only service this amp required was a insignificant cleaning of the pots and contacts. It now works perfectly without noise or distracting pot distortion.
