Grover Mini Locking Rotomatics (406 Series) 3+3 Tuners

Grover Mini Locking Rotomatics (406 Series) 3+3 Tuners

Rotomatic® tuners that automatically lock the string as you tune. For 3-left/3-right pegheads.

Internal-cam locking string posts and 18:1 fine tuning are built into Rotomatic midsize cast housings to fit 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.
Also available for 6-in-line pegheads.

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 pegholes required.

Installation Tips

Mounting screws: Pilot holes required. Installing delicate screws into hard wood requires great care and accuracy. We highly recommend the #1712 Depth-stop Drill Bit (5/64" bit) for the pilot hole before installing these screws. Lubricate the screw threads with cutting lubricant (also wax or a bar of soap) to reduce friction and help them thread properly.
