Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine delivers outstanding precision and smooth tuning comfort with an upgraded 1:18 gear ratio. Continuing the legacy of the original closed-housing design introduced in 1966, this modern iteration incorporates high-precision CNC manufacturing and surface finishing to ensure consistent, highly sensitive, and stable performance.
Equipped with high-grade brass string posts precisely fitted into the housing, this tuning machine provides maximum wear resistance and tuning stability. The self-locking drive and permanently lubricated sealed housing utilize specialized grease for completely maintenance-free operation over years of reliable play.
Installation is streamlined thanks to the stepped collar washer design, which cleanly centers the string post via the banjo bolt and eliminates the need for stepped headstock drilling. This smart engineering eliminates tilting torque and reduces mechanical stress on both the post and rear mounting screws.
