I have a chance to buy this guitar. It's in great shape and plays wonderfully but there are two questions: 1. It really looks like an Ebony fretboard. Was this an option? 2. The back of the neck has a satin rather than gloss finish. It goes up onto the ears of the headstock symmetrically, seems very well done. Was this an option or an aftermarket mod? And for the bonus, how much does the "scuffing" of the neck change the value if it IS aftermarket?
