Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine delivers outstanding precision and tuning comfort with an upgraded 1:18 gear ratio. Designed with CNC-machined components and surface finishes, it features a self-locking drive that ensures consistent, responsive, and stable tuning.
Equipped with high-grade brass string posts engineered precisely into the housing, this tuning machine provides maximum tuning stability and wear resistance. The innovative stepped M6 flanged washer ensures straightforward installation and precise post centering without requiring a stepped peghead bore.
Each closed machine head is permanently lubricated with Schaller special grease for completely maintenance-free operation. The two-pin mounting configuration shares identical housing dimensions with previous models for seamless installation.
