Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets an industry standard for precision and tuning stability. Engineered with high-precision CNC manufacturing, it features a 1:18 gear ratio that delivers smooth, highly sensitive tuning and reliable performance. All internal posts are crafted from high-grade brass and fitted precisely into the housing to eliminate wear.
Featuring the innovative M6 flanged washer with step, this tuning machine simplifies headstock installation while reliably centering the string post. The stepped washer design eliminates tilting moments and relieves mechanical strain from both the post and rear mounting screws without requiring stepped headstock drilling.
Every enclosed M6 unit is permanently lubricated with proprietary Schaller grease for entirely maintenance-free operation. Designed with a dual-pin configuration at a 10 mm spacing and an 8 mm pin-to-post center distance, it delivers rugged mounting stability for modern solid headstock instruments.
