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; screws and knurled press-fit bushings included. Drill the peghole to 5/16" (7.94mm) and ream the face with our standard peghole reamer.
Tip: 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.
