Grover 406C Chrome 3+3 Mini Locking Rotomatic Tuning Machines

Internal-cam locking string posts and 18:1 fine tuning are built into familiar Rotomatic full-size cast housings for 3-left/3-right pegheads. As you tune, the post automatically locks the string. You'll need fewer string wraps, change strings faster, and your tremolo will have more accurate return-to-pitch.

These full-size Rotomatic tuners feature large removable metal knobs with adjustable tension, cast gear housings with lifetime sealed lubrication, and 18:1 gear ratio for fine tuning. Sets of 6, for 3-left/3-right pegheads.

Mounting screws and threaded hex peghead bushings with washers are included. 10mm (13/32") diameter pegholes required.
