Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine delivers outstanding tuning stability and velvety-smooth performance with an upgraded 1:18 gear ratio. Designed as an evolution of the legendary original sealed tuner first introduced in 1966, this modern version features precision CNC-machined components and a self-locking drive mechanism to ensure consistent, highly sensitive, and slip-free tuning.
Crafted with premium brass string posts precisely fitted into the housing, the M6 Pin is engineered for complete wear resistance and reliable longevity. It features the innovative stepped M6 flanged washer, which centers the string post securely via the threaded bushing, eliminating tilting torque and removing unnecessary strain from both the post and mounting hardware without requiring stepped headstock boreholes.
Equipped with permanent lifetime lubrication using proprietary Schaller grease, these sealed tuners operate maintenance-free under heavy playing conditions. Designed with dual mounting pins spaced 10 mm apart, they offer direct replacement compatibility for corresponding tuner layouts while providing superior mechanical precision.
