1973 Marshall JMP 50 Watt Lead Head – Converted to Super Bass Spec by Friedman!

Here we have an awesome 1973 Marshall JMP 50 Watt Lead Head. This amp is in overall very good shape for it’s age. There are several extra holes that have been plugged from previous mods that have been undone by Dave Friedman when he switched the amp to super bass specs. The ohm selector has been switched to a 3 way toggle switch. Chassis is mostly original with only the needed filter caps changed during routine maintenance.  The amp features it’s original Drake transformers. It sounds incredible. There’s nothing like the natural overdrive from these amps.
