As always, the quality of a Seymour Duncan is superior to most brands.
First off, don't expect this one to sound like a full sized humbucker, 'cause it doesn't. It sounds more like a single coil on steroids.
Don't let the Maiden boys' crappy guitar sound discourage you, this one sounds killer.
I put this in a swamp ash body and it was a perfect fit with great balance from bass to treble. Off course, it's in bridge position acting as a hot rhythm single coil where it responds good to rolling off the volume for a warmer, less distorted sound. Since it has that hot feel to it, I'm gonna buy one more and install it in neck position. Crazy? Yeah maybe...but how cool wouldn't shredding sound with that hot single coil-sound in neck position??
