Health Checkup: 1979 Marshall JMP 50w

Joey Brasler brings his 1979 Marshall JMP by the shop for Steve to give some TLC. There’s discussion about the mod Steve installed in the amp 35 years ago, the general maintenance Alexander Dumble performed on the amp as well as the usual bench nerdery and bad jokes that happen during these episodes. Enjoy! #joeybrasler #dumble #fryette #marshalljmp #amprepair #vintageamps
