High quality machines with 12:1 ratio, sealed lubrication, adjustable knob tension, cast housings, threaded hex peghead bushings and removable metal knobs.
All Schaller M6 tuners require 10mm (13/32")-diameter pegholes. Sold in sets of 6, with mounting screws, threaded bushings and washers included.
Mounting screws: Pilot holes required. Installing delicate screws into hard wood requires great care and accuracy. We highly recommend the #1713 Depth-stop Drill Bit (No.44 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.
