Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers exceptional tuning precision and smooth operation with an advanced 1:18 gear ratio. As an evolution of the legendary 1966 original, it features precision CNC-machined components with a self-locking drive mechanism for outstanding tuning stability and wear-free performance.
Equipped with high-grade brass string posts and factory-applied special grease lubrication, each sealed tuner is completely maintenance-free. The innovative stepped M6 flanged washer ensures effortless installation and solid post centering through the threaded bushing without requiring a stepped peghead bore.
Engineered for seamless drop-in replacement on existing instruments, the M6 180 design eliminates tilting torque and reduces mechanical stress on both the string post and rear mounting screws.
