I have a 1993 Strat Plus that I got late last year. I think they're great guitars, but one thing I noticed is that with the locking tuners, the lock wheels can come off when loosened all the way. With the newer Schaller locking tuners (and other brands too), I believe they're made so that the lock wheels don't fall off when loosened all the way. I've wondered if it would be worthwhile to put newer Schaller locking tuners on the Strat Plus so I don't have to worry about the lock wheels coming off. Do you think it would be worthwhile? One thing is I haven't seen any new Schaller locking tuners in the matte color that came with the Strat Plus.. The new ones all seem to be chrome/nickel, black, or gold.
