Fender Deluxe Bass Tuning Machines with Fluted Shaft.

Set of four tuning machines for use on most modern Precision Bass and Jazz Bass guitars. Wider at the top than the bottom, the fluted shafts force the string windings downward and keep them tight, resulting in a sharper and consistent break angle over the nut, creating increased sustain and better tuning stability.
