What can you tell me about this bass? I bought it in about 1975, and it sat in the closet/basement ever since. When I took it out last year the nut was split in pieces by the strings. It's light blue, single pickup, 30 in. scale length. Worth setting up, or Ebay material? Another question. The nut slot is radiused, similar to the fretboard. Can I get nut blanks that are curved on the bottom or do I have to cut one to fit? Thanks.
