Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers outstanding precision and tuning comfort with an upgraded 1:18 gear ratio. All components are CNC-machined to exacting tolerances, surface-finished, and equipped with a self-locking drive for smooth, highly stable tuning.
Solid brass string posts are fitted precisely into the housing to ensure maximum tuning stability and wear-free operation. The stepped M6 flanged washer reliably centers the post through the threaded bushing, eliminating tilting moments without requiring a stepped peghead bore.
Permanently lubricated with Schaller special grease for entirely maintenance-free longevity, this closed tuner features two mounting pins with a 0.39 in center-to-center pin spacing and a 0.31 in pin-to-post distance.
