Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets an industry benchmark for precision and stability. Equipped with a refined 1:18 gear ratio, it delivers an exceptionally smooth, accurate tuning process. Every component is CNC-machined to exact tolerances, paired with premium brass string posts fitted precisely into the housing to guarantee wear-free performance and superior tuning retention.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation while reliably centering the string post directly via the hollow screw. This smart design eliminates tilt torque and relieves mechanical stress from both the post and the rear mounting hardware without requiring stepped peghead drilling.
All enclosed internal mechanisms come permanently lubricated with Schaller high-grade grease for completely maintenance-free operation over a lifetime of use. Precision-engineered self-locking drives ensure ultra-responsive, consistent adjustments that keep your instrument sounding its best.
