Grover Roto-Grip Locking Rotomatic (502 Series) 3+3 Tuners

Fast string changes and non-slip tuning! Rear thumbscrew locks the string for non-slip tuning and fast string changes. For 3-left/3-right pegheads.

Traditional Rotomatics® with a twist! Simply wind the string once, tighten knob, and tune to pitch! You'll need fewer string wraps, change strings faster, and your tremolo will have more accurate return-to-pitch.

For 3-left/3-right pegheads only. For 6-in-line pegheads, see Grover Roto-Grip Mini Locking Guitar Machines.

Full-size Roto-Grip tuners for 3-left/3-right pegheads feature:
• 18:1 gear ratio for precise tuning
• Cast gear housings with no-hassle lifetime sealed lubrication
• Traditional large Rotomatic removable metal knobs

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