Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine offers exceptional tuning precision and stability with an enhanced 1:18 gear ratio. Designed with CNC-machined components and high-grade brass string posts, it ensures smooth operation and reliable performance without wear over time.
Featuring the innovative stepped flanged washer, this tuning machine aligns the string post through the banjonut seamlessly without requiring stepped peghead boreholes. This design eliminates tilting torque and reduces structural strain on both the post and mounting screws.
Engineered to match the exact installation dimensions of its predecessor, the M6 135 serves as a direct drop-in replacement for effortless upgrades. Every unit is permanently lubricated with Schaller special grease for completely maintenance-free functionality.
