These are complete sets of 4-left/4-right tuners on two baseplates, with removable pearloid plastic knobs.
Standard 29/32" (23mm) string post spacing; screws and knurled press-fit bushings included. 11/32"-diameter (8.73mm) pegholes required.
Available in two different gear configurations: #5675 with worm gear under string post (turn the the knob counterclockwise to tighten the string) #5674 with worm gear over string post (turn the knob clockwise to tighten the string) Important: These two styles may not be interchangeable on the same peghead. See Specs before ordering.
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.
