Grover mandolin tuners feature engraved die-cast baseplates, plus 18:1 gear ratio. These are complete sets of 4-left/4-right tuners on two baseplates, 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.
To be sure these tuners fit your instrument, compare your existing machines and peghole dimensions to our listed specs to help determine the best replacement.
