1974 Marshall JMP 100 Super Bass, model # 1992. Amp is in very very good condition. Wiring has had only minor componets replaced,no mods, and features original tranformers. Chassis is very clean, Tolex is very very good with the exception of a small area that has been torn and reglued on the bottom of side (see pictures). No extra holes in chassis or cabinet. Please note one of the mounting nuts is missing on chassis so only three screws hold chassis in cabinet. Amp sounds 'godlike' just like a vintage JMP Super Bass 100 should.I think you could look a long time before you find a better example.Amp will be packed well in an oversize box and fully insured. Please feel free to call for an accurate in hand discription, Jerry cell# 541 661 1963.
