Grover A-Style 409 Mandolin Tuning Machines

Engraved die-cast baseplates, 18:1 gear ratio. Complete sets of 4-left/4-right tuners, with equal-length knob shafts and removable pearloid plastic knobs.

Standard 29/32" (23mm) string post spacing. Drill the peghole to 5/16" (7.94mm) and ream the face with our standard peghole reamer.

Each set includes:
• Pair of 4-left, 4-right tuning machines
• Removable pearloid plastic knobs
• Press-fit peghead bushings
• Mounting screws

Installation Tips

Peghole spacing: Plate-mounted tuners can't work efficiently if the pegholes are improperly drilled. Our Mandolin Peghead Drill Jig ensures precise 29/32" spacing for accurate alignment for these tuning machines.

Bushings: We recommend the #2061 Bushing Reamer (.328" diameter) to cut a clean, accurate counterbore for a professional job. Fit the press-fit tuner bushings correctly so your tuners will work smoothly.

Mounting screws: Pilot holes required. Installing delicate screws into hard wood requires great care and accuracy. We highly recommend the #1714 Depth-stop Drill Bit (3/32" 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.
