Hey Guys. First posting, so bear with me. I recently purchased a 1951 Kay bass in awesome shape. Only, the FB has ruts/worn grooves at the A & D strings at the C & F position. When playing a C, you'll get a little rattle going on. My question is ...Does this qualify as a complete FB dressing or is there a way to repair just the worn spots? The rest of the FB is good. Thanks in advance for any help!
