Today one of my partners was telling me that he's dating a girl who used to play bass in a band years ago. She brought over her '73 P-bass to show him. It's natural with a clear finish. He says it looks great, except a strip of damaged finish on the back, where it looks like maybe some glue in the original case attacked the finish. Has anyone seen what this vintage of P-bass is going for? Just curious. He says she also has a Mustang bass that she thinks is a '59. Did they even make Mustangs in '59? I thought something like that might have some collector value, even if it isn't the best bass they ever made.
