Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with its refined 1:18 gear ratio. Designed with high-precision CNC-machined components and high-grade brass posts, it ensures outstanding tuning stability and completely wear-free performance.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post without requiring a stepped peghead bore. This design eliminates tilting torque and reduces mechanical stress on both the post and mounting screws.
Permanently lubricated with Schaller special grease, all enclosed mechanisms remain completely maintenance-free. While engineered with slightly more compact housing dimensions than its historic predecessor, it drops directly into place without structural modifications.
