Hey folks, I recently picked up a 1974 Marshall Superlead that I was told belonged to George Lynch. It was modified by Lee Jackson (Metaltronix) and sounds amazing. Stenciled on the back is L-1. I know that Lee Jackson did indeed modify some amps for George, but have no idea if my 74' was one of them. Can any of you cats shed some light on this? I love the amp and paid a decent price, so if it wasnt George's, I'm cool with that. It would be nice to know one way or another though. And oh yeah, I can send pics if there is an interest. Peace!!
