Grover Mini Locking Rotomatics (406 Series) 6-In-Line Tuners

Rotomatic® tuners that automatically lock the string as you tune. For 6-in-line Headstocks

Internal-cam locking string posts and 18:1 fine-tuning are built into Rotomatic midsize cast housings to fit 6-in-line 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 midsize Rotomatic tuners feature compact metal knobs with adjustable tension, lifetime sealed lubrication, and 18:1 gear ratio for fine-tuning. Sets of 6.

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