Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers refined performance and tuning stability with an improved 1:18 gear ratio. Designed for smooth and precise adjustment, all components are CNC-machined and surface-treated with a self-locking drive mechanism to maintain pitch accuracy over extended playing sessions.
Crafted with premium brass string posts fitted precisely into the housing, these enclosed tuning machines offer exceptional wear resistance. The innovative stepped M6 collar washer ensures straightforward installation and lasting post centering without requiring stepped headstock drilling, effectively eliminating tilting torque.
Permanently lubricated with Schaller special grease for maintenance-free operation, this two-pin set is engineered for standard pin spacings. Each set includes mounting hardware, hollow screws, and collar washers for a complete, professional upgrade or replacement.
