Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin tuning machine delivers unmatched precision and smooth tuning comfort with an upgraded 1:18 gear ratio. Continuing the legacy of the original 1966 closed-housing design, this refined version incorporates modern engineering improvements while retaining its iconic look.
Precision CNC-machined components and high-grade brass string posts ensure superior tuning stability, minimal wear, and a self-locking drive mechanism. Each sealed unit is permanently lubricated with Schaller special grease, providing completely maintenance-free operation over a long service life.
The innovative stepped M6 flanged washer centers the string post reliably through the banjonut, eliminating tilting torque and reducing stress on mounting hardware without requiring stepped peghead counterbores.
