Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents precision engineering and modern innovation built on an iconic legacy. Featuring an improved 1:18 gear ratio, it ensures precise, velvet-smooth tuning and exceptional tuning comfort. Every component is CNC-machined with high accuracy and surface-treated to guarantee consistent, responsive, and stable performance.
Crafted with premium brass string posts precisely fitted into the housing, this tuning machine delivers optimal tuning stability and long-lasting wear resistance. The innovative stepped M6 flanged washer centers the string post securely without requiring a stepped headstock hole, eliminating tilting torque and reducing pressure on both the post and mounting screws.
Designed for permanent reliability, all enclosed tuning machines are lubricated for life with special Schaller grease, making them completely maintenance-free. The compact housing design allows direct drop-in replacement for previous versions without requiring headstock modifications.
