Nailbomb - I think it's best for hard rock, but it's really versatile, I've heard here Nailbomb clips ranging from blues to death metal. I have mine quite close to the strings, and I use it primarily for hard rock and (kind of) progressive metal. It cleans up really well when I turn down the volume, though. If I adjusted it a little bit lower, it'd be probably great for less gainier styles as well.
