Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine delivers refined tuning precision and exceptional mechanical stability. Featuring a 1:18 gear ratio, it ensures smooth, accurate string tension adjustments with a self-locking drive mechanism. High-precision CNC-machined components and solid brass string posts provide wear-free longevity and outstanding tuning reliability.
Equipped with an innovative stepped collar washer, this tuner allows straightforward mounting and reliable shaft centering via the hollow screw, removing the need for stepped headstock drilling. This optimized structure eliminates tilt momentum and evenly absorbs mechanical pressure from both the post and fixing rear components.
Permanently lubricated with specialized grease, the closed housing is completely maintenance-free. Designed with a dual-pin configuration at a 0.4 in (10 mm) pin-to-pin center distance and a 0.3 in (8 mm) spacing to the post center, it provides a direct, solid anchor on compatible guitar headstocks.
