Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers state-of-the-art tuning precision and stability with an upgraded 1:18 gear ratio. CNC-machined components and high-grade brass string posts ensure velvety-smooth operation, self-locking drive reliability, and wear-free performance.
Featuring the innovative stepped flanged washer, this tuner allows precise centering of the string post via the banjo bolt without requiring stepped headstock drilling. This design eliminates tilting torque and reduces mechanical stress on mounting screws and internal components.
Permanently lubricated with Schaller special grease for maintenance-free longevity, the M6 135 retains standard footprint dimensions for seamless drop-in replacement on existing headstocks.
