I'll say this much...believe it, don't believe, doesn't matter to me but back in the 90's I worked at the Amphitheater in Nashville, worked in the administration. Sadly the original Amphitheater is long gone, great times...especially for me when it came to gear and having an all access admin pass. Scorpions, Rush, Kiss, Dokken etc...you name it, if I could I scoped their rigs out. Sometimes you'd have a prickly tech, sometimes not.
In Ed's case...it was all there. Rig, guitars...easy to see. On those two tours it was all Peavey. No hidden amps or rack cases, no rehoused units...it was the 5150. In fact the only non Peavey amps that I saw were on the 2nd of those two tours and were Marshalls that were used for his piezo's. In fact the second tour he was playing his prototype Peavey guitars which his tech gladly let me see. Most of those rigs have been photographed and documented, it's out there and was exactly as I saw. Actually the most interesting thing about it was how open his tech was and on each tour his tech had numerous 6L6's laid out on a towel. I'm sure Ed played alot amps in the studio during that era but on those two tours, at that venue, what I saw were 5150 rigs. Was there for the VHIII tour as well but too busy to check the rig out...the album and tour tanked but I've always said, that was the best live guitar tone I've ever heard.
