They also work great clean, and not just 'metal' clean, a real clean. I've made this quick clean demo on Amplitube using a Bassman and Deluxe models.
I plan on recording another using a very light edge-of-breakup setting as they can also fit that genre nicely. I wouldn't attempt to argue that they are the greatest of pickups and for most applications I would still choose a PAF style pickup over them, but they're not just a one-trick-super-high-gain-pony.
