Schaller M6 90 Guitar Tuning Machine

The Schaller M6 90 guitar tuning machine delivers outstanding precision and tuning comfort with its improved 1:18 gear ratio. All components are CNC-machined to exact tolerances, surface-treated, and permanently lubricated with Schaller special grease for maintenance-free operation and smooth performance.
Featuring high-grade brass posts precisely fitted into the housing, this tuning machine provides maximum tuning stability and wear resistance. The self-locking drive ensures consistent and delicate string adjustments under all playing conditions.
An innovative stepped flanged washer centers the string post securely via the hollow screw, preventing tilt and eliminating the need for stepped headstock boreholes. It features identical installation dimensions to its predecessor for direct replacement without instrument modifications.
