Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers outstanding precision and tuning comfort with an upgraded 1:18 gear ratio. CNC-machined components with premium surface finishes ensure velvet-smooth, ultra-stable operation backed by a self-locking drive mechanism.
High-grade brass string posts are fitted precisely into the housing to maximize wear resistance and tuning stability. Each closed tuning machine comes permanently lubricated with Schaller special grease for completely maintenance-free performance.
Featuring the innovative stepped M6 flanged washer, this tuner aligns the post securely without requiring stepped headstock drilling. This design eliminates tilting torque and reduces strain on both the string post and rear fixing screws.
