Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin tuning machine sets a benchmark for closed-type guitar tuners, featuring an upgraded 1:18 gear ratio for ultra-precise and smooth tuning response. Engineered with high-precision CNC manufacturing and surface finishing, every unit utilizes a self-locking drive that provides consistent, delicate adjustment and steadfast tuning stability.
Crafted with premium brass string posts fitted tightly into the housing, the M6 Pin delivers exceptional wear resistance and long-lasting performance. The innovative stepped M6 flanged washer centers the string post securely through the hollow screw, preventing tilt and eliminating the need for step-drilling in the headstock.
Permanently lubricated with specialized Schaller grease, these maintenance-free tuning machines ensure effortless operation. Designed with dual rear mounting pins featuring a 0.39 in center-to-center spacing, they provide a secure fit and reliable instrument upgrade.
