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. Each component is CNC-machined to exact tolerances and surface-treated to provide consistent, stable tuning backed by a self-locking drive.
Crafted with premium high-grade brass string posts fitted precisely into the housing, these tuners ensure maximum wear resistance and rock-solid pitch stability. All enclosed mechanisms are permanently lubricated with Schaller special grease for completely maintenance-free performance.
Installation is simplified through the innovative stepped M6 flanged collar, which centers the string post securely through the hollow screw without requiring stepped headstock drilling. This smart design eliminates tilting torque and relieves mechanical stress on both the post and mounting hardware.
