well i've just finished todays practice with an hour long jam, and i spent most of that on the neck VHII coil tapped. it sounded seriously good, much strat-ier than you might expect, particularly when stuck through a clean boost and a wah into a plexi model - i was briefly in tone heaven! both me and my tech agree that, for whatever reason, when coil-tapped BK's tend to send more like a real singlecoil than others we've come across.
for me, coil-tapping is a viable alternative because im not in a position to be able to afford another guitar, just my LP. Also, i cant drive so i couldnt get multiple guitars to and from jams and auditions, so its nice to have a great bucker and a convincing coil-tap in the one package.
However, as TO was specifically asking about the bridge pickup, i have to be honest, i almost never use this coiltapped. Every once in a while i turn it on, usually if im in the middle position on the pick-up selector and i don't want the bridge bucker to dominate the coil tapped neck. But i still got it done because it cost me no extra and its not particularly complex or anything, so i figured i might as well get it done.
