Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers exceptional tuning accuracy and smooth operation with an improved 1:18 gear ratio. Designed to replace its predecessor without modifications, it features identical installation dimensions while incorporating modern engineering enhancements.
Precision CNC-machined components and high-grade brass posts ensure maximum tuning stability, wear resistance, and sensitive adjustment. The stepped M6 flanged washer centers the string post securely without requiring stepped headstock drilling, eliminating tilt torque and protecting mounting hardware.
Permanently lubricated with Schaller special grease for maintenance-free longevity, these sealed tuners provide dependable performance across a wide range of headstock configurations and clamping options.
