Does it have to be a humbucker? I'm not a big fan of the Strat bridge pickup & some of the Tokai pickups are too thin & bright for my tastes. The Duncan Twangbanger is supposed to sound like a Tele bridge pickup & I reckon it gets a good half way there. About 8k, fatter & warmer than most Strat bridge pickups but it doesn't overload position 2. No routing necessary. I love 'em.
It doesn’t have to be a humbucker, but I would prefer a high output bridge. I usually play with gain so that’s why I was gearing towards a Dimarzio super distortion S since its got a little more beef on the bass end
