Sorry, but this is my territory Bought the green iceman, the J signature. Also an 8100 and a Randall.
Astro creep was 3 Randall Century 200 amps and one Marshall 8100 Valvestate. All at the same time during a splitt kinda thing. Also different cabinets.
Read it all in guitarmagazines during that time.
Live J used Century 20 stacks, some with a tubescreamer.
Afterr the splitup of of WZ J sold some of his Randall's and he bought himself a Recto. But he never recorded a Recto.
