Featuring precision 16:1 ratio, sealed lubrication, cast housings and removable metal knobs, these are some of the finest tuners available.
The large metal Schaller-style knob is the same as found on many modern guitars. 10mm (13/32")-diameter pegholes required. Sets include mounting screws and threaded hex bushings.
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.
