hi, i look on ebay at the bewildering selection of vintage fender basses. are certain years more collectable than others because there were less made that year? are some years known for their 'magic tone?' the last 3 top selling jazz basses were 1966. im aware condition plays a huge role in prices, its just odd to me to see a bass sell for 3 grand, and then someone else has a buy it now for the same year @ 14k. any general pointers are appreciated. johnny a.
