Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers refined tuning precision and rock-solid stability with an upgraded 1:18 gear ratio. Each component is CNC-machined to exact tolerances and permanently lubricated with Schaller special grease for smooth, maintenance-free operation.
Equipped with high-grade brass string posts engineered for wear resistance, these enclosed tuners utilize an innovative stepped flanged washer that centers the post securely through the peghead without requiring stepped drilling. This design eliminates tilting torque and reduces mechanical strain on both the post and mounting hardware.
Featuring dual rear alignment pins with 0.39 in. (10 mm) center-to-center spacing, the M6 Pin offers straightforward installation on compatible headstocks. Premium surface finishing and self-locking drive mechanics ensure accurate, slip-free tuning performance.
