Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine delivers state-of-the-art precision and exceptional tuning comfort with its 1:18 gear ratio. All components are CNC-machined to exacting tolerances, surface-finished, and permanently lubricated with Schaller special grease for completely maintenance-free performance.
Featuring high-grade brass string posts engineered for maximum wear resistance, this tuning machine provides uncompromising tuning stability. The self-locking internal drive mechanism ensures smooth, sensitive, and dependable string adjustments during every session.
Equipped with an innovative stepped M6 flanged collar with a 0.39 in diameter, the unit centers the string post securely through the threaded bushing without requiring stepped headstock drilling. This design eliminates tilting torque and protects both the post and mounting hardware from unnecessary stress.
