Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine combines legendary design with advanced engineering, featuring a refined 1:18 gear ratio for exceptionally smooth and precise tuning stability. Each component is high-precision CNC-machined and surface-finished, utilizing a self-locking drive mechanism to ensure uniform, sensitive, and dependable operation.
Crafted with premium brass string posts precisely fitted into the housing, this tuning machine guarantees maximum wear resistance and pitch retention. The closed housing design is permanently lubricated with proprietary Schaller grease, making it completely maintenance-free throughout its service life.
Featuring the innovative stepped M6 collar washer with a 0.39 in (10 mm) base, the assembly accurately centers the string post via the banjo bolt without requiring stepped headstock drilling. This design absorbs mechanical pressure, eliminates tilting torque, and delivers secure installation.
