Have you thought about Curtis Novak's Fatbucker? It was designed to be a drop-in replacement for a Gibson mudbucker, with a sound which is roughly the opposite of the mudbucker - i.e. clanging trebles, a deep, tight bass response, and not too much mud or wooliness. To my ears, it sounds a lot like my old 1972 Telecaster bass, which was one of the most beautiful-sounding basses I have ever owned - something like a really fat P-bass, crossed with an aggressive Rickenbacker!

Good luck in finding the tone that is right for you!
