Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers outstanding precision and smooth tuning action with an upgraded 1:18 gear ratio. All components are CNC-machined to exact tolerances, premium finished, and engineered with a self-locking drive mechanism for stable, sensitive adjustment.
Precision brass string posts fit securely within the housing to ensure optimal tuning stability and long-lasting wear resistance. An innovative stepped M6 flanged collar reliably centers the string post via the hollow bolt without requiring stepped headstock drilling, effectively eliminating tilt torque and relieving stress on both post and mounting components.
Equipped with permanent lubrication using Schaller specialized grease, these enclosed tuning machines remain completely maintenance-free. Designed with a dual-pin configuration and a standard 0.39 in center-to-center pin spacing, they offer seamless replacement and dependable performance for discerning guitarists.
