Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers precision and tuning comfort with its refined 1:18 gear ratio. Designed with CNC-machined components and high-grade brass string posts, it ensures velvety-smooth operation, self-locking stability, and long-term wear resistance.
Featuring the innovative stepped M6 flanged washer, this tuner allows effortless installation and solid centering without requiring stepped peghead drilling. This design eliminates tilting moments and relieves tension from both the string post and rear mounting screws.
Every enclosed tuner is permanently lubricated with specialized Schaller grease for completely maintenance-free performance. Its slightly refined housing dimensions fit standard footprints seamlessly without requiring instrument modifications.
