I am lucky to have been given a old Fender P bass. The serial #(-21175 on the 4 bolt neck plate) dates it to 1958 I think. But I think it is maybe a 1968 from the history I am told. Maybe the plate was switched? ANYWAY would these pickups get old? Would new ones sound better?? Certainly technology has changed. It sounds good; plays GREAT. It is noisy if hand contact is not made with the strings though. Thanks.
