Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine delivers outstanding precision and tuning comfort with an improved 1:18 gear ratio. Continuing the legacy of the original 1966 closed-type tuner, this modern design combines classic aesthetics with refined engineering.
Every component is precision CNC-machined and surface-finished, featuring self-locking mechanics for uniform, ultra-smooth, and stable tuning. High-grade brass posts are precision-fitted into the housing to guarantee maximum tuning stability and wear-free operation.
Equipped with an innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post without requiring stepped headstock boreholes. Closed housings come permanently lubricated with Schaller special grease for completely maintenance-free performance.
