I have an SX fretless o) with rather sharp fingerboard edges. Can anybody suggest a good method for smoothing them out, or point me to a thread/sticky with some info? (I did search, but not exhaustively). I thought about just sanding them down (doesn't have to be a really polished job), but then I'm not sure how to treat the exposed wood after that. Would it be fine? What are my options? Thanks for the help!
