Damn - away for a couple days, and come back amazed at the attention this thing has gotten. Thanks all!
And finally got some more quality time with it, and I'm really liking these pickups. They're the "Seymourized" Firebird pickups, and they really are a great combination of chime and grit. I just got about the most perfect Malcolm Young tone I've ever gotten with any guitar - call me a fan.
