Love these in the bridge position of my Strats, was wondering just how high/low others have them set at?
Set to taste of course, but understanding the Rails magnetic circuit may help you out. A traditional single coil sprays a strong magnetic field up at the string like a water fountain. You can get farther away from the string and still have a robust tone. In the Rails configuration, the blade from one coil (south) is in pretty close proximity to the other blade (north) so the magnetic field is pulled from one blade to the other. It looks like a really shallow arch or rainbow, not a water fountain. For this reason, changing the distance from the strings of a Rails pickup has more affect on the output and tone than the same distance range on a standard single coil. I like them pretty close to the strings.
I use the neck model and I found that I had to set it pretty high.
I actually screwed the bass side down a few extra turns to brighten it up a little.
I'd say 1/2" at the most.
Not sure about the bridge......
