Some people's sweat is acid. Count my son among them, must have something to do with puberty and that spring fountain of testosterone he has in him. No finish can withstand - he could always get a job in the aging department of the Gibson Custom Shop.
Actually, I don't find it so ugly, but it is weird that the wear and tear concentrates on the rim area of the maple top only. If he really did that himself just by playing the thing then that particular DeLuxe was both well-loved and well-used.
Incidentally, the above pic is helpful to see the non-roller bridge Gibson used on those five string DeLuxe LPs (and the Specials too). Might be from Schaller as well.
