|  |     In the years after Fender was sold to CBS, quality suffered.  As
    a result, Pre-CBS equipment is more highly valued.  This is not to
    say that all pre-CBS stuff is great and all post-CBS stuff is
    terrible, but in general, pre-CBS quality is better.  Also, the 
    years following the post-CBS move, some changes were made in
    the instruments that are considered less desirable (e.g., three
    bolt necks).
    
    The collectors market has driven the prices of pre-CBS gear through
    the roof.

|  |     My guess is that Jaco Pastorius is almost singlehandedly responsible
    for the outrageous prices on pre-CBS Jazz basses.  Jaco paid something
    like $90 for his (with a case!).  As Jim says, pre-CBS Fenders are in
    demand because of quality and also 'mystique', but this alone doesn't
    account for the prices on J's.  You'll pay about twice as much for a
    comparable year/condition J-bass as you will for a Precision.
    
    Of course, they are great basses too.
