Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin tuning machine delivers unmatched tuning precision and silky-smooth operation with its refined 1:18 gear ratio. Engineered as the modern evolution of the legendary original closed tuner standard, it incorporates state-of-the-art enhancements while preserving its iconic heritage.
Precision CNC-machined components, durable surface finishes, and high-grade brass string posts ensure long-lasting tuning stability and wear-free performance. Each sealed tuner is permanently lubricated with Schaller special grease for completely maintenance-free reliability.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation by eliminating the need for a stepped headstock bore while securely centering the string post and neutralizing tilting forces.
