My '63 sounds great but I've played others from the '60s that weren't so great. Bottom line is ymmv no matter the year, and this includes the '70s imo when it was tough to find a very good Fender but there were a few great ones as well.
Also the last I looked my '63 Precision had 4 screws holding the neck on.
