Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and smooth tuning comfort with an improved 1:18 gear ratio. All components are CNC-machined to exact tolerances and surface-finished, while the self-locking drive ensures consistent, delicate, and stable tuning performance.
Crafted with premium brass string posts precision-fitted into the housing, these tuners guarantee maximum tuning stability and wear-free operation. The enclosed design is permanently lubricated with Schaller special grease for completely maintenance-free functionality over its entire lifespan.
Featuring the innovative stepped M6 flanged washer with a 0.39-inch diameter base, the string post centers securely without requiring stepped headstock holes. Sharing identical installation dimensions with its legendary predecessor, it serves as a direct drop-in replacement without instrument modification.
