So Floyd Rose seems to introduce another series (as if there wasn't enough already) but this one has a cool feature with the hex screw arm holder (similar to Gotoh Floyd). Can't find much about it on the net.
Seems like they only exist on new 2015 Schecter guitars for the moment.
Has anybody got any other info?
From what I remember, they have stainless screws and saddles, as well as modified knife edges. The locking nut also had stainless steel clamps and screws. There was some page explaining all the features an FR1500 had, but it was taken down.
