Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and tuning comfort with an improved 1:18 gear ratio. All components are CNC-machined to exact tolerances, surface-finished, and equipped with a self-locking drive for smooth, delicate, and stable tuning.
Featuring high-grade brass string posts precisely fitted into the housing, this machine head guarantees maximum tuning stability and wear-free performance. The innovative stepped M6 flanged washer centers the post reliably via the hollow screw, preventing tilting moment and eliminating the need for a stepped peghead hole.
Permanently lubricated with Schaller special grease for maintenance-free operation, the M6 135 maintains identical installation dimensions to its predecessor for a seamless direct replacement.
