Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine delivers legendary performance with refined precision and modern engineering. Designed with an improved 1:18 gear ratio, it ensures exceptionally smooth, sensitive, and accurate tuning stability across every performance.
Crafted with CNC-machined components and premium brass string posts, each tuner fits precisely into the housing to eliminate wear and provide reliable, self-locking operation. The integrated stepped flanged washer centers the string post securely without requiring stepped headstock drilling, effectively eliminating tilt torque and protecting mechanical components.
Each closed-housing mechanism comes permanently lubricated with Schaller specialty grease for completely maintenance-free longevity. Designed with a 0.39-inch (10 mm) dual-pin spacing, it offers seamless replacement for legacy single-pin M6 configurations.
