Grover A-Style 309 Mandolin Tuning Machines

About This Item

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 Standard Peghole Reamer to cut smooth, perfectly round holes.

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.

Replaced the stock tuners on my Trinity mandolin. The stock tuners were rubbish and had to go. Now with the Grovers, it sounds a lot better and stays in tune. A highly recommended upgrade. Thanks Grover and Stewmac.

These Grover Mando Tuners are unbeatable! I use them on all my builds and I'm getting ready to purchase some for the Cigar Box UKE that I'm currently building! Thanks for all you do Mr Stewmac!

Excellent product! Drop in fit on my The Loar LM-300 mandolin. Had to fill the old screw holes (3) and drill new ones (5), but no big deal. I would like a choice of tuner knobs as standard, but black ones are available. They function much better than the original equipment, in my opinion.
