Double-locking Tremolo System

A tremolo system patented by Floyd Rose, also called a “double-locking vibrato“. A double-locking system is so named because both the floating bridge and the nut clamp down on the strings, locking them in place and preventing them from going out of tune when the vibrato arm is used and abused. The concept behind a double-locking system is that there are three points at which the strings can bind or slip out of tune when a vibrato arm is used: the bridge saddles, the nut, and the tuning machines. By clamping the strings at the bridge and the nut, all three of these points are removed from the tuning stability equation.
