Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin tuning machine delivers exceptional tuning accuracy and smooth operation with its refined 1:18 gear ratio. Continuing the legacy of the original 1966 design, this closed guitar tuner features CNC-machined components with a self-locking drive mechanism that ensures stable and delicate adjustment.
Crafted with premium brass string posts, each unit is precisely fitted into the housing to maximize tuning stability and minimize wear over extended use. The innovative stepped M6 flanged washer centers the string post securely, eliminating tilting torque and removing stress from both the post and mounting hardware without requiring stepped headstock holes.
Equipped with permanent internal lubrication using specialized grease, this tuning machine operates completely maintenance-free. Designed with dual mounting pins spaced at 0.39 in (10 mm) center-to-center and an offset of 0.31 in (8 mm) to the string post center, it provides a solid and seamless installation.
