Re: Humbucker Bridge/Single Neck Tele
You could get a Duncan Custom shop tele-sized single wound a la strat. Lew has one, and I've not heard him berate it at all.
Or a Fralin Blues special-that's a bright, strong, chimey sounding neck pickup that's akin to a strat as well. I currently use it and am pretty happy with it. It is not covered so you won't have that jangley rhythm sound, but it is a great pickup-very open and percussive.
As for the bridge mix-I'd suggest a 59-although I've not tried that particular combination.
