Grover Original Rotomatics (102 Series) 3+3 Tuners

Popular since the '60s, Rotomatic tuners are now available in 2 gear ratios. For 3-left/3-right pegheads.

Rotomatic® full-size tuning machines feature large removable metal knobs with adjustable tension, cast gear housings and lifetime sealed lubrication. 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.

For 6-in-line pegheads, see Grover Midsize and Mini tuning machines.

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.
