Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine combines legendary design with modern precision, featuring an upgraded 1:18 gear ratio for exceptionally smooth and accurate tuning. Each unit is CNC-machined to exact tolerances, paired with premium brass string posts to ensure outstanding tuning stability, self-locking drive reliability, and wear-free operation.
Equipped with Schaller's innovative stepped collar washer (0.39 in diameter), the tuner centers the post securely through the threaded bushing without requiring stepped headstock drilling. This smart design eliminates tilting torque and relieves mechanical stress from both the string post and rear mounting points, while sealed internal housings lubricated with proprietary Schaller grease offer lifetime maintenance-free performance.
Engineered for direct replacement and custom configurations, the M6 Pin utilizes a two-pin rear mounting pattern with a standard 0.39 in center-to-center pin spacing and an 0.31 in post-to-pin offset. Every tuner is crafted with precision-matched components, providing superior functionality and professional-grade durability for demanding guitarists.
