Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets a benchmark for closed-type tuners, featuring an upgraded 1:18 gear ratio for exceptionally precise and smooth tuning performance. Precision CNC-machined components and high-grade brass posts ensure optimal tuning stability, wear resistance, and reliable self-locking operation.
Equipped with an innovative stepped M6 flanged washer, this tuner allows effortless installation while firmly centering the string post via the banjo bolt. This specialized design eliminates tilting torque and relieves mechanical stress from both the post and rear mounting screws without requiring stepped headstock drilling.
Permanently lubricated with specialized Schaller grease for maintenance-free operation, the two-pin housing maintains exact footprint compatibility with legacy single-pin Schaller models with a 0.4 in (10 mm) pin-to-pin spacing.
