Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin tuning machine sets a high standard for enclosed tuners, featuring an upgraded 1:18 gear ratio that provides velvety-smooth action and precise tuning control. All internal components are CNC-machined and surface-treated for maximum wear resistance and consistent, self-locking operation.
Equipped with high-grade brass string posts engineered for an exact fit inside the housing, this machine head offers superior tuning stability. The specialized stepped M6 flanged washer reliably centers the string post via the banjo bolt, effectively eliminating tilt and relieving excess pressure without requiring a stepped peghead hole.
Each closed housing is permanently lubricated with proprietary Schaller grease for entirely maintenance-free performance. Designed with a dual-pin mounting format, it directly matches previous Schaller single-pin footprint dimensions for a clean, stable installation.
