Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets an industry benchmark for precision and tuning stability. Engineered with a refined 1:18 gear ratio, it provides exceptionally smooth, accurate adjustments for all playing styles. High-precision CNC machining and high-grade brass string posts ensure wear-free, consistent operation across the lifespan of your instrument.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation while ensuring continuous, rock-solid axis centering. The stepped washer design reliably centers the string post through the banjo bolt and eliminates tilting torque without requiring stepped drilling in the headstock.
Each sealed tuner is permanently lubricated with Schaller special grease for completely maintenance-free performance. Built to exact tolerances, the M6 Pin delivers exceptional durability, structural rigidity, and classic craftsmanship.
