Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and smooth tuning comfort with an upgraded 1:18 gear ratio. All components are CNC-machined to exact tolerances and surface-finished to ensure uniform, sensitive, and stable tuning performance.
Equipped with high-grade brass string posts engineered seamlessly into the housing, this tuning machine provides maximum tuning stability and wear resistance. Closed-gear internal mechanisms are permanently lubricated with Schaller special grease for completely maintenance-free operation.
The innovative stepped M6 flanged washer centers the string post securely via the hollow screw, eliminating tilting torque and eliminating the need for a stepped peghead bore while perfectly matching the mounting dimensions of its predecessor model.
