If I were you, I'd go with (preferably) an older DiMarzio Model J pup. They match up lovely with the stock Fender P pup. Or, if you're feeling adventurous, replace both of 'em with DiMarzios. When you play it, it'll sound like a blanket has been removed from your speaker cab. Excellent, excellent pickups. And, relatively cheap, too, compared to other brands.
