Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine delivers precise tuning stability and velvety-smooth performance with an upgraded 1:18 gear ratio. Each component is CNC-machined to exact tolerances and permanently lubricated with Schaller special grease for maintenance-free operation.
Equipped with high-grade brass string posts precisely fitted into the housing, this tuning machine provides maximum wear resistance. The innovative stepped M6 flanged washer centers the string post securely through the banjo bolt without requiring a stepped peghead bore, eliminating tilting torque.
Featuring dual mounting pins with a 0.39 in center-to-center spacing and a 0.31 in distance from pins to string post center, this model ensures seamless installation and rock-solid alignment on compatible instruments.
