Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin tuning machine delivers precise and smooth tuning performance with its advanced 1:18 gear ratio. Designed with CNC-machined components and a self-locking drive, it provides exceptional tuning stability and sensitive, accurate adjustments.
Crafted with premium brass string posts fitted directly into the housing, this machine head prevents wear and ensures maximum durability. The enclosed mechanism is permanently lubricated with Schaller special grease, making it completely maintenance-free over its entire service life.
Featuring the innovative stepped M6 flanged washer, it centers the string post reliably through the hollow screw without requiring stepped peghead boreholes. This design eliminates tilting torque and relieves mechanical stress on both the string post and rear mounting screws.
