Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine features a refined 1:18 gear ratio that delivers smooth, precise tuning control and exceptional pitch stability. High-precision CNC-machined components and high-grade brass string posts ensure wear-free, consistent operation across all performance conditions.
Equipped with the innovative stepped M6 flanged washer, this tuning machine simplifies installation and permanently centers the string post without requiring a stepped peghead bore. This design eliminates tilting torque and reduces mechanical stress on both the post and rear mounting screws.
Permanently lubricated with Schaller special grease, the enclosed housing provides reliable, maintenance-free longevity. Designed with a dual-pin configuration and an 0.39 in center-to-center pin spacing, it offers seamless replacement for legacy single-pin housings.
