According to an interview in Guitar Player in 1998 (or '99?) he uses Shure SM-57's or Shure Beta-57's for close micing the amp (in the studio he also uses a Neuman for ambience, if I remember correctly). It's kinda hard to tell from the photos from the recent Stray Cats tour, though. But 57's are pretty much what everybody uses, so he probably still does too.
