Ideal tuners for fixing up those not so valuable, but dearly loved instruments.
14:1 ratio with white plastic knobs. Nickel-plated.
29/32" (23.02mm) string post spacing.
5/16" (7.94mm) diameter pegholes required.
Each set includes:
• Pair of 4-left, 4-right tuning machines
• Press-fit bushings
• Mounting screws
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 #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.
