Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers legendary performance with a refined 1:18 gear ratio for ultra-precise and smooth tuning action. Each component is CNC-machined to exact tolerances, featuring precision brass posts fitted cleanly into the sealed housing to provide exceptional tuning stability and wear resistance.
Equipped with Schaller's innovative stepped M6 flanged washer, this machine head centers the string post securely through the threaded bushing without requiring step-drilled peghead holes. This smart design eliminates tilting torque and disperses tension away from both the post and the rear mounting screw.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, the M6 135 maintains identical installation dimensions to its predecessor for direct replacement without instrument modifications.
