I was reading Chris Kinman's article on how to keep stock, Strat trems in tune & one thing that wasn't mentioned was that Phantom Guitarworks (www.phantomguitars.com) is now manufacturing locking saddles for these units that, according to quite a good number of players who've tried 'em, tend to work pretty well when used w/ a set of locking tuners & a Graphtech Trem-Nut or other frictionless-type nut. Guess the guys at Phantom figured that it was okay to go ahead & do this since, as we all know, Floyd Rose's patent ran out a while ago. Anyway, just thought I'd mention that. Laters!
