Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a high standard for precision and tuning stability with an improved 1:18 gear ratio. All components are high-precision CNC-machined and surface-treated, featuring a self-locking drive mechanism that guarantees smooth, sensitive, and reliable tuning performance.
Crafted with premium brass string posts precisely fitted into the housing, these tuners offer exceptional wear resistance. The innovative stepped M6 flanged washer ensures straightforward installation and permanently solid centering of the axis without requiring a stepped bore in the headstock.
Permanently lubricated with Schaller special grease, each enclosed tuner is completely maintenance-free. Designed with a dual-pin configuration featuring 0.39 in center-to-center pin spacing and 0.31 in spacing to the post center, it provides reliable stability across varied playing styles.
