Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine offers precision and stability with an improved 1:18 gear ratio for smooth, sensitive tuning. Engineered as the modern evolution of the legendary original closed tuner, it retains the classic mounting dimensions for seamless replacement without modification.
Featuring CNC-machined components with premium surface finishing and self-locking drive mechanisms, this tuner utilizes high-grade brass posts fitted tightly to the housing to maximize wear resistance and tuning retention. Permanent lubrication with Schaller special grease ensures completely maintenance-free operation.
The innovative stepped M6 flanged washer reliably centers the string post without requiring step-drilled headstock holes, eliminating tilt torque and relieving pressure from the post and mounting screw.
