Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine delivers outstanding precision and smooth tuning comfort with an upgraded 1:18 gear ratio. Designed with CNC-machined components and surface finishing, its self-locking drive ensures consistent, sensitive, and stable tuning performance.
Crafted with premium brass string posts precisely fitted into the housing, this tuning machine provides maximum tuning stability and wear-free operation. Closed tuning machines come permanently lubricated with Schaller special grease for completely maintenance-free longevity.
The innovative stepped M6 flanged washer reliably centers the string post without requiring a stepped headstock bore, eliminating tilting torque and reducing mechanical stress. Featuring identical mounting dimensions to its predecessor, it allows direct, modification-free replacement.
