Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine combines legendary design with modern precision, featuring an enhanced 1:18 gear ratio for smooth, accurate tuning. High-grade CNC-machined brass string posts fit precisely into the sealed housing to provide exceptional tuning stability and long-lasting durability.
Equipped with Schaller's innovative stepped flanged washer, this tuning machine ensures effortless mounting and precise centering over the banjo bolt without requiring a stepped peghead bore. This design eliminates tilting torque and protects both the string post and rear mounting screws from excess strain.
Each closed machine head is permanently lubricated with Schaller special grease for completely maintenance-free operation. Engineered with self-locking precision gearing and a standardized two-pin housing footprint, it delivers reliable, sensitive, and stable string tension adjustment.
