ESP Mighty Vise Floyd Rose FRT-3 This is a tremolo unit that can be installed on Tune-O-Matic bridges, such as those found on Les Paul guitars. This type is a historically valuable part, as it was released by ESP before the original Floyd Rose. This is an auction for the bridge unit only, but its locking nut apparently came with fine tuners, which also predates Floyd Rose.
