Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning precision and stability with its refined 1:18 gear ratio. Designed with high-precision CNC-machined components and surface finishes, the self-locking drive ensures smooth, sensitive, and reliable string tuning across all playing styles.
Equipped with high-grade brass string posts fitted accurately into the housing, these tuners provide maximum tuning retention and wear resistance. The innovative stepped M6 flanged washer centers the string post securely through the threaded bushing without requiring stepped headstock holes, eliminating tilt torque and protecting mounting screws.
Permanently lubricated with Schaller special grease, each enclosed unit operates completely maintenance-free. These tuners offer an effortless drop-in replacement for earlier M6 housings without requiring headstock modifications.
