Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for enclosed tuners, featuring an upgraded 1:18 gear ratio for smooth, accurate, and stable tuning. Every component is CNC-machined to exacting tolerances and treated with a premium surface finish, while a self-locking drive mechanism ensures consistent tension and prevents slippage.
Built with premium brass string posts carefully fitted into the housing, this tuning machine delivers high tuning stability and wear-free performance. The innovative stepped M6 flanged washer reliably centers the string post without requiring a stepped headstock bore, effectively eliminating tilting torque and reducing stress on mounting components.
Each sealed tuner is permanently lubricated with Schaller special grease for completely maintenance-free operation. Engineered with a 10 mm pin spacing and an 8 mm center-to-post distance, the M6 Pin offers a seamless upgrade path for guitars using standard pin-mount configurations.
