I thought Gibson people hated Burstbuckers? If it wasn't vintage or boo-teak (and preferably little-known, insanely expensive, and impossible to get hold of) they weren't having it.
Irony is, when the Burstbuckers were only installed on Gibson guitars that were being sent to Japan, the Gibson people raved about them. Today's Burstbuckers are somehow "different." Maybe they are.
In my opinion, the Burstbuckers are not so bad. A bit compressed for my tastes, but not the worst pickups by any means.
Anyway, I think Burstbuckers are AV.
