Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine delivers outstanding precision and smooth operation with an improved 1:18 gear ratio. All components are CNC-machined to exact tolerances, surface-finished, and permanently lubricated with Schaller special grease for maintenance-free reliability.
Equipped with high-grade brass string posts engineered for maximum tuning stability, each unit integrates a self-locking drive mechanism. The innovative stepped M6 flanged washer eliminates tilting torque and centers the string post securely without requiring a counterbore in the headstock.
Designed with a 0.39 in (10 mm) pin spacing, the M6 Pin ensures stable anchoring and direct alignment. These premium machine heads offer versatile configurations to match diverse instrument designs and headstock thicknesses.
