The Dimebucker is a terrific pickup for most styles except maybe Lawrence Welk!
I think Robert S. put one in a Les Paul and was very happy with it. Robert's a rocker but he's not a heavy metal or grunge type player...although I'm sure he can play that way if he feels like it!
One nice thing about rails pickups like the Dimebucker is that there is no decrease in volume or sustain when you bend a note. Often there is a little change in sustain and the feel of the note with pickups with polepieces when you bend the note and bend it between polepieces. With rails, the pole piece is always right under the string no matter where the string is being bent to.
