1974 Marshall JMP Lead MK II 50W

Here’s a vintage 1974 Marshall JMP Lead Mk II Model 1987 50W electric guitar amplifier head. This particular example, serial number 1636F, is in extremely excellent original condition and includes a vintage custom Anvil ATA case! This early printed circuit board (PCB) version is every bit as powerful as its Plexi predecessor,and this particular head was completely serviced to be prepared for serious studio use, as well as, the most demanding live situations. A custom Anvil case was outfitted for this exact head many years ago, and it has successfully preserved this amp in very excellent cosmetic condition ever since.

Serial Number: 1636F
Inspection Date: 28-1-74 (Jan. 28, 1974)
Transformer Codes: 1202 – 164, 784 – 139

Aside from a few replaced caps and upgraded power tubes, this example is all original. The original black levant tolex is in near perfect 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!
