Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers exceptional tuning precision and velvet-smooth operation with its improved 1:18 gear ratio. As an evolution of the legendary original sealed tuner introduced in 1966, this model incorporates refined engineering and state-of-the-art CNC manufacturing for flawless performance.
Crafted with premium high-grade brass string posts and a self-locking drive mechanism, the M6 180 ensures maximum tuning stability and wear-free durability. Each enclosed unit is permanently lubricated with proprietary Schaller special grease, making the internal mechanics completely maintenance-free.
Installation is streamlined via the innovative stepped M6 flanged washer, which centers the string post precisely through the banjo bolt and eliminates tilting torque without requiring stepped peghead counterbores. This design reliably relieves mechanical stress from both the post and rear mounting screws for extended instrument reliability.
