Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine delivers precise tuning comfort and unmatched accuracy with an upgraded 1:18 gear ratio. All components are CNC-machined to precise tolerances and finished for high-grade performance, utilizing a self-locking drive mechanism that guarantees smooth, sensitive, and stable tuning.
Crafted with premium brass string posts precision-fitted into the housing, this tuning machine provides maximum tuning stability and long-lasting, wear-free operation. The closed housing design is permanently lubricated with specialized Schaller grease, rendering the unit completely maintenance-free.
Featuring the innovative M6 stepped flanged washer with a 0.39-inch diameter base, it reliably centers the string post through the banjo bolt and eliminates the need for stepped headstock drilling. This design absorbs tilting moment and reduces mechanical stress on both the post and rear mounting screws.
