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. It's a historically valuable part, as this type was released by ESP before the original Floyd Rose. This listing is for the bridge unit only, but its locking nut apparently had fine tuners, which also predates Floyd Rose.
