Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine features a refined 1:18 gear ratio that delivers exceptional tuning precision, smooth action, and long-term stability. Built upon the legendary closed-housing design first introduced in 1966, this updated model integrates modern innovations while preserving classic styling and direct retrofittability.
Every component is precision CNC-machined and finished for consistent operation and self-locking drive reliability. High-grade brass posts ensure wear-free longevity, while factory-sealed lubrication using specialized grease eliminates the need for ongoing maintenance.
Installation is streamlined via the stepped M6 collar washer with a 0.39 in (10 mm) diameter base, which self-centers the string post securely through the banjo bolt without requiring stepped headstock drilling. This innovative design eliminates tilting torque and reduces mechanical stress on mounting screws and string posts.
