I own a MIM Fender Jazz Bass with stock pickups. I'm planning on getting new pickups in it soon.(looking at seymour duncan) How much work would it be for a tech to put one jazz pickup in either the bridge or neck position, and a humbucker in the other, If it's worth it. Which spot is better in your opinions for the humbucker. Is seymour duncan a good idea, or should I just sit down and shut up?
