Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers refined performance and tuning comfort, driven by an advanced 1:18 gear ratio for smooth, precise adjustment. Built with high-precision CNC-machined components and durable surface treatments, it incorporates a self-locking drive that provides consistent, highly stable tuning.
Crafted with premium brass string posts precision-fitted into the housing, this tuning machine ensures maximum wear resistance and rock-solid pitch stability. The innovative stepped M6 flanged washer reliably centers the string post via the banjo bolt, eliminating tilting torque and removing the requirement for stepped headstock drilling.
Permanently lubricated with Schaller special grease for maintenance-free operation, this two-pin configuration maintains identical housing dimensions to legacy single-pin models. Designed with an 8 mm center distance between the mounting pins and the post axis, it offers seamless replacement and outstanding mechanical reliability.
