Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and tuning comfort with an improved 1:18 gear ratio. Continuing the legacy of the original 1966 closed-gear design, this updated model integrates modern innovations while preserving classic performance.
Each component is CNC-machined to exacting tolerances and surface-treated for maximum durability. Solid brass string posts are precision-fitted into the housing to guarantee exceptional tuning stability, smooth action, and wear-free operation.
Equipped with an innovative stepped flanged washer, the M6 180 centers the string post securely without requiring a counterbore in the headstock. Sealed permanently with specialized lubricant, these tuning machines are completely maintenance-free.
