Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine delivers outstanding precision and smooth tuning comfort with an upgraded 1:18 gear ratio. CNC-machined from premium components, it features a self-locking drive and high-grade brass string posts engineered for wear-free durability and maximum tuning stability.
An innovative stepped M6 flanged washer ensures straightforward installation and precise string post centering without requiring stepped headstock drilling. This design eliminates tilting torque and reduces strain on both the string post and rear mounting screw, extending the longevity of your instrument's hardware.
Each enclosed tuning machine is permanently lubricated with Schaller special grease for completely maintenance-free operation. Built to identical mounting dimensions as its predecessor, the M6 135 provides an effortless, direct-fit replacement upgrade for existing setups.
