Eddie was never terribly concerned with the aesthetics of his guitars beyond his trademark stripes. Wear and tear was a good thing. As beautiful as his EBMM sigs were, he just used and abused them. Michael Anthony even recounted once that Ed was frustrated that Mike had a bass that looked too beautiful - figured wood, nice finish, no wear. So he grabbed it from Mike and made gouges in the front of it with a screwdriver. Mike was pissed, but the damage was done.
Back in the day, this is something that made EVH who he was. It was an awkward learning curve, but he never really adhered to conventional... anything, if he could help it.
