Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers state-of-the-art precision and tuning comfort with an upgraded 1:18 gear ratio. As the modern evolution of the legendary original enclosed tuner introduced in 1966, it incorporates premium mechanical innovations for unmatched stability.
Every component is high-precision CNC-machined and surface-finished, featuring high-grade brass string posts precisely fitted into the housing to ensure wear-free, self-locking operation. The enclosed housing comes permanently lubricated with Schaller special grease, making each machine completely maintenance-free.
The innovative stepped M6 flanged washer centers the string post securely without requiring stepped headstock drilling, eliminating tilting torque and reducing mechanical stress on mounting hardware.
