Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents precision engineering with a refined 1:18 gear ratio, delivering ultra-smooth operation and superior tuning stability. Designed as a modern evolution of the classic closed-housing standard established in 1966, it features high-precision CNC-machined components and a self-locking drive mechanism for reliable, backlash-free performance.
Equipped with premium brass string posts precisely fitted into the housing, this tuning machine maximizes wear resistance and vibrational transfer. The innovative stepped M6 flanged washer reliably centers the string post through the threaded bushing without requiring stepped headstock drilling, eliminating tilt torque and protecting mechanical components.
Permanently lubricated with Schaller special grease for maintenance-free longevity, the M6 180 can directly replace previous-generation housings without guitar modifications. Mounting hardware including banjo bolts, flanged washers, and M2.2 x 9.5 screws is included for straightforward installation.
