Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin tuning machine delivers exceptional tuning precision and stability with an advanced 1:18 gear ratio. Designed for smooth, velvet-like operation, each component is precision CNC-machined and permanently lubricated with Schaller special grease for maintenance-free longevity.
Crafted with premium high-grade brass string posts fitted precisely into the housing, this closed tuner minimizes wear while maximizing tuning stability. The self-locking drive ensures consistent, responsive performance across all playing conditions.
Featuring the innovative stepped M6 flanged washer, this tuning machine reliably centers the string post without requiring a stepped headstock bore. This design eliminates tilting moment and relieves mechanical stress from both the post and the rear mounting screw.
