I have a pair in my Greco bird. At least, the guy I got em from on ebay claimed they were Chandlers.
Funny thing is, they sound almost identical to the Greco pups! Not that that's a bad thing. Maybe they're marginally brighter, but based on other peoples' comments (and some sound samples somebody here posted long ago, maybe on the old dudepit) I kind of expected them to have a bit more treble than I get from them.
