1976 Marshall JMP Super Lead 100 in nice shape. Get your earplugs out, cause this baby is super loud. However, it does sound pretty nice at low volumes. A bit of hum on the one channel but the other is minimal. Works really well overall.
Looks to be all original with no mods aside from what is stated below. No guarantees as this amp is of course quite vintage.
No back panel. 3 prong cord added. Minor wear on the tolex. Little rust on the handle.
