Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine delivers state-of-the-art precision and performance with its refined 1:18 gear ratio, ensuring a smooth and exact tuning experience. Setting the benchmark for closed tuners since 1966, this updated design incorporates precision CNC-machined components and premium surface finishes for reliable, self-locking stability.
Crafted with high-grade brass string posts engineered seamlessly into the housing, these tuners provide exceptional wear resistance and long-term tuning integrity. Permanent lubrication with Schaller special grease guarantees maintenance-free operation across years of continuous playing.
An innovative stepped M6 flanged washer centers the string post accurately without requiring stepped headstock boreholes. This integrated engineering feature eliminates tilting moments and relieves tension from both the post and rear mounting screws for a solid, straightforward installation.
