Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers outstanding precision and smooth tuning performance with its refined 1:18 gear ratio. All components are CNC-machined to exacting tolerances and surface-finished, featuring a self-locking drive that guarantees velvety, sensitive, and stable tuning.
Crafted with precision-fitted brass string posts, these sealed tuners ensure maximum tuning stability and wear-free operation. Every unit comes permanently lubricated with Schaller special grease for completely maintenance-free longevity.
An innovative stepped M6 flanged washer reliably centers the string post without requiring a stepped headstock bore, effectively eliminating tilting torque and reducing strain on both the post and mounting hardware.
