My experience of buying a YOB bass (and indeed my observance of others purchasing a YOB bass), is that they rarely work out. I understand the sentiment behind it, but purchase a bass because it speaks to you and feels great, not based on the year it was made.
After all, what are the chances of two awesome things being made in the same year?!
That said, maybe I'm just bitter and being born in '83, a pretty dry period, especially for Fender
