Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and smooth tuning performance with its refined 1:18 gear ratio. CNC-machined components and premium brass string posts ensure maximum tuning stability, wear-free longevity, and responsive operation across all playing styles.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post without requiring a stepped headstock bore. The specialized design effectively eliminates tilting torque while relieving mechanical pressure from both the post and rear mounting screws.
Permanently lubricated with Schaller special grease, the sealed housing provides completely maintenance-free performance. Retaining identical installation dimensions to its predecessor, it allows direct, modification-free retrofitting on compatible solid or slotted guitar headstocks.
