I noticed that the old American Deluxe P-Basses had an almost MM-style humbucker in the rear. The new ones all have a J pickup in the bridge position. Some people swear by the humbucker, but I have a buddy who owns a Fender Tony Franklin fretted and that is one of the best basses I've ever heard. Has anyone played both before? What's the difference in tone and what do you prefer?
