Grover Mid-Size Rotomatics (305 Series) 3+3 Tuners

Rotomatic® midsize tuners feature compact removable metal knobs with adjustable tension, lifetime sealed lubrication and 18:1 gear ratio for fine tuning.

These midsize cast housings fit 3-left/3-right pegheads.
Also available for 6-in-line pegheads.

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 #1711 Depth-stop Drill Bit (No.50 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.
