Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 tuning machine offers unparalleled tuning precision and stability with its refined 1:18 gear ratio. Designed with CNC-machined components and high-grade brass string posts, it ensures smooth, wear-free, and velvety tuning performance for modern guitarists.
Featuring the innovative stepped M6 flanged washer, this tuning machine provides effortless installation and self-centering without requiring stepped headstock drill holes. This mechanism eliminates tilting torque and reduces strain on both the string post and rear mounting screw.
Each closed-type tuner is permanently lubricated with Schaller special grease, making it completely maintenance-free. With identical mounting dimensions to its predecessor, it serves as a direct, modification-free replacement upgrade.
