Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets an industry benchmark for precision and tuning stability, featuring a refined 1:18 gear ratio that ensures smooth and ultra-accurate adjustments. Built with high-precision CNC-machined components and self-locking drive mechanisms, this enclosed tuner delivers consistent, delicate, and slip-free performance.
Crafted with premium brass string posts precisely fitted into the housing, the M6 Pin offers exceptional wear resistance and long-term tuning reliability. The innovative stepped M6 flanged washer centers the string post securely through the hollow screw, eliminating tilting torque, reducing stress on the mounting screws, and removing the need for stepped headstock drilling.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, these tuners are engineered for versatile configurations. Designed with a 10 mm (0.4 in) pin-to-pin spacing and 8 mm (0.3 in) post-to-pin center distance, they provide effortless installation and rock-solid performance.
