The Sentient (6 string version) is a very nice sounding neck pickup aimed mainly at the broad Metal genre, but it has a really nice, warm sound capable of pretty much anything you throw at it. You don't have to sacrifice tone for output, it's perfectly suited for clean chords, nice crunchy solos and creating really good sounds with the volume rolled off. I bought it together with it's matching Bridge Pickup, the Nazgul, and the outputs of those match each other very well, no adjusting of volume necessary. There really isn't anything not to like about it, as long as the clear and natural sound of a passive Humbucker is what you desire.
The installation was easily done with the provided wiring diagram and it looks pretty slick with the black-in-black look, instead of the usual silver "dots".
A great Pickup all around and easily worth the money!
