Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents an advanced evolution of a legendary closed-gear design. Engineered with a refined 1:18 gear ratio, it delivers velvety-smooth tuning action and exceptional pitch accuracy. Every component is CNC-machined with high precision and surface-treated for lasting performance, while the self-locking drive ensures consistent and stable tuning.
Crafted with premium brass string posts precisely fitted into the housing, the M6 180 provides maximum tuning stability and wear resistance. It features the innovative Schaller stepped flanged washer, which centers the post via the banjonut and eliminates the need for stepped headstock holes while absorbing tilt torque and reducing stress on mounting screws.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, these tuners offer direct replacement compatibility for legacy M6 units without headstock modifications. They provide professional-grade reliability and smooth operation for demanding players and builders alike.
