Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers exceptional precision and tuning comfort with an upgraded 1:18 gear ratio. All components are CNC-machined and surface-treated, featuring a self-locking drive mechanism that guarantees smooth, sensitive, and stable tuning.
Equipped with high-grade brass string posts engineered for wear-free performance, this closed machine head incorporates an innovative stepped flanged washer. This washer reliably centers the string post without requiring a stepped peghead bore, eliminating tilting torque and reducing pressure on both the post and mounting screws.
Featuring the exact installation dimensions of its predecessor, the M6 135 is permanently lubricated with Schaller special grease for completely maintenance-free operation and seamless replacement.
