Thanks for all the comments.
I've got Tim's reply. To be fair, I gave him a lot more info, saying I wanted a bridge pickup that was a bit thicker (especially on the top E) and could do a passable P90 impression, and a neck that was clear and Strat-like.
He recommended the Piledriver bridge (a big surprise to me) combined with a Yardbird or Blackguard Flat 50 neck.
The Yardbird sounds ideal. Reading up on the Piledriver, I think I'm warming to the idea, especially as I like Fender's Broadcaster in the Baja Teles. What concerns me is that it might be a bit too hot and compressed, and lose a bit too much top end. Can anyone chip in with their Piledriver thoughts?
