I'm playing a 1990s Marshall JMP1 Rack Preamp through the power amp of a Marshall 1987X and a 1971 Marshall 1960A 4x12 using a 1973 Gibson Les Paul Custom. This amp has been used by so many of my favorite players, for instance Billy Gibbons and Dave Mustaine.

2016 Marshall 1987X 50W lead Plexi reissue (only Power Amp)
