I'm looking to upgrade my 2004 MIM Fender Jazz Bassfor but I can't decide which pickups. I like the look and price of the Bart's, but I've also heard that the Fender Custom Shop 60's pickups are great (comparable.in price). Which would you guys recommend? And are they that different sound wise? I'm looking for a good classic jazz bass sound, and really anything better than the stock pickups that are on it (of which are horrible).
