"Pat Badger: Oh yeah. I have one picture that I’m holding the Frankenstrat in 5150 and leaning on his Plexiglas Marshall that he used on all the early shit. So I’m holding the guitar and leaning on the amps that recorded 'Eruption.' It doesn’t get much better than that really for a Van Halen fan."

We were led to believe Van Halen recorded his early stuff with one variac'd (magic) amp and one cab. Not so. Ed variaced his Superlead amp and then lined out that signal to a Marshall P.A.
Judging by jnew's awesome tests http://forum.metroamp.com/viewtopic.php?f=16&t=44867 Eddie probably recorded with his Superlead variac'd down to 70 volts and then pushed the speakers hard with the volume on the Master P.A.
