Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry standard with an upgraded 1:18 gear ratio for velvety smooth, highly precise tuning stability. All components are CNC-machined to exacting tolerances, surface-treated, and permanently lubricated with Schaller special grease for maintenance-free operation.
Crafted with high-grade brass string posts engineered precisely into the housing, the M6 135 ensures maximum durability and wear resistance. The self-locking drive mechanism provides consistent, sensitive, and rock-solid pitch retention under active playing conditions.
Featuring the innovative stepped M6 flanged washer, the unit mounts effortlessly without requiring stepped headstock drilling. This design eliminates tilting torque and distributes pressure away from the string post and rear mounting screw, while maintaining identical mounting dimensions to legacy models for direct drop-in replacement.
