I was reading the A pickup you totally hated? thread, and it made me curious to know the opposite. What's a pickup that really stood out? Before you answer: I don't want this thread to be a list of your favorite pickups--there's already a bunch of those (e.g. any pickup recommendation thread). My experience and expectation is that a pickup swap results in a minor change. I'm curious for instances that went way beyond that expectation. I want to hear about experiences where it wasn't just incrementally better, but was like a whole new revelation about what a pickup could do. Be as specific as you can.
