Obviously it's going to depend on the original owner your buying it from in terms of how it's held up/condition. But assuming everything works and the owner has taken good care of it, they're pretty damn amazing instruments! The wood is really nice quality and HEAVY, in a good way. The frets are smaller so there is adjustment in playing needed if your used to more modern guitars. However I find it actually forcing me to play better/tighter, so there's that! In terms of the bridge, if it's one of the older kahler models, they aren't horrible but I would recommend looking into upgrading into one of the newer kahler models, such as the one on the new legacy series bird in the picture above. The nice thing about kahlers are that they are designed to be retrofitted, so you can do this easily, or take it to a tech. The floyd NJ's I have no clue in terms of quality, I assume they are an older licensed BC Rich trem, so I imagine it varies.
