I have decided I cant afford a new bass and so I want to upgrade my MIM Deluxe Jazz with new pickups. Im a novice in the world of pickups, but I saw an advert for bass player pickups in BP magazine. Ive been on their website and their active jazz pickups look quite nice. But I cant really tell anything from this, so does anyone have any experience with these pickups? What are they like? What other pickup manufacturers should I look into? Im also thinking of installing a new pre amp in my bass, as the Fender one can be a bit noisy some times. Again I dont really know anything about pre amps so what kind of things should I look for? I dont have a huge amount of money to spend, and I play mostly jazz with some rock and funk. Thanks for any help.
