Re: Strat pickup replacements
The Vintage Rails is the best side-by-side single sized humbucker I've tried for getting the clear tone of a single. The Duckbucker is basically the V.R. with adjustable poles, and I find that to be a drawback. They're too small. The magnetic field now has to transport through these tiny little dots. The rails blades aren't any thicker, but they're solid. Because of my non-love affair with the little screw poles, I personally would maybe try the Dimarzio tracks instead. I have a Fast Track that I love, so maybe the Chopper in the bridge, Vintage Rails middle, and Cruiser in the neck. Or for a little more oomph all the way around, a Fast Track 2 bridge, Fast Track 1 middle, Pro Track neck.
If you go hotter like that, then there's still enough output in those pickups to coil split them for an extremely clean vintage strat type of sound. If you chose the first recomendation, then the output would be usable if you split them, but you'd probably find it very low.
