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. Designed to set the standard for enclosed tuners, it features precision CNC-machined components with a self-locking drive that provides consistent, highly sensitive, and stable tuning performance.
Crafted with premium brass string posts carefully fitted into the housing, this tuning machine ensures maximum tuning stability and long-lasting wear resistance. The innovative stepped M6 flanged washer centers the string post perfectly via the threaded bushing without requiring stepped headstock drilling, effectively eliminating tilt and relieving stress on mounting points.
Each enclosed tuner is permanently lubricated with Schaller special grease for completely maintenance-free operation. Engineered for precise fitment, this high-grade machine head combines robust engineering, effortless installation, and reliable performance for demanding players.
