Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine sets a benchmark for enclosed tuners with its refined 1:18 gear ratio, delivering velvet-smooth action, pinpoint tuning accuracy, and long-lasting stability. Each component is precision CNC-machined and surface-treated, featuring high-grade brass string posts engineered for wear-free performance.
Equipped with Schaller's innovative stepped collar washer (0.39-inch diameter), the string post automatically centers via the threaded bushing without requiring stepped headstock drilling. This design eliminates tipping torque and relieves stress on both the drive axis and rear fixing screw.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, the M6 180 directly replaces legacy housings without modification, offering self-locking drive mechanics and exceptional tuning reliability.
