Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets an industry benchmark for precision and stability. Engineered with a refined 1:18 gear ratio, it delivers velvety-smooth tuning response and exacting accuracy for professional performance. Each component is CNC-machined to exacting tolerances and permanently lubricated with Schaller special grease for maintenance-free operation.
Crafted with premium high-grade brass string posts, the M6 Pin ensures maximum tuning stability, wear resistance, and long-term durability. The innovative stepped M6 flanged washer centers the string post securely without requiring stepped headstock drilling, eliminating tilt torque and protecting mounting hardware from mechanical stress.
Designed with a 10 mm pin spacing and an 8 mm center-to-post distance, this tuning machine drops directly into compatible headstocks while offering self-locking drive mechanics for reliable, slip-free performance across all playing styles.
