Jimmy Page actually used vox amps quite alot after the first couple albums. And who know that his tele had really thin strings on it (8s) and his supro was not too different from a fender twin but he used a solasound tonebender fuzz pedal in front of it. But Jimmy used many amps and the marshalls were only used live. In studio he used a few supros, vox amps, hiwatts, and I think he had a couple fenders. As for guitars he had multiple strats, three teles (1 ruined after the first tour), I believe 4 les pauls that he used in studio including the black beauty that was stolen, a fender xii, a rickenbacker, a danelectro (which was said to be used only live and that a tele was used for recording what sounds like it), and of course he used the doubleneck sg live. I studied this for a while but I am not saying that I am totally accurate as page never really fully evaluted on his studio gear to the public.
