Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers exceptional tuning comfort and precision with its refined 1:18 gear ratio. As an evolution of the industry-standard enclosed tuner introduced in 1966, this modern iteration incorporates advanced design enhancements while preserving legendary performance.
Precision-engineered components are CNC-machined and surface-treated to guarantee smooth, responsive, and stable tuning through a self-locking drive mechanism. High-grade brass string posts are fitted securely into the housing to maximize wear resistance and ensure optimal tuning stability across playing styles.
Equipped with an innovative stepped M6 flanged washer, this tuner allows straightforward installation while keeping the post solidly centered without requiring stepped peghead counterbores. All enclosed assemblies are permanently lubricated with proprietary Schaller grease for lifelong, maintenance-free operation.
