Like they've said, they're all over the map; the ones I liked best were from the Norlin era, the one McCarty era one I had I gave away to a friend (that's how much I liked it), the recent era ones have ranged from what a pile to real good, I can not comment on the Custom Shop models as I've never owned one, the brand new Gibson USA models have gone in a different direction.
That is the truth as I know it.
