I am looking to change out the pickups in my Fender P Bass Lyte. This bass is equipped with factory Fender pickups, split p/u at the neck and a humbucker at the bridge (both active). I have decided on Seymour Duncan Quarter Pound neck pickups, but I am having difficulty choosing a replacement for the bridge pickup. I am looking for fatter bottom end than I am getting with my current setup and more punch in the high end (I get plenty of volume from my high end, but it sounds "thin" to me). If anyone can offer any suggestions I would appreciate it.
