Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers precise and smooth tuning performance with an upgraded 1:18 gear ratio. Engineered with precision CNC-machined components and surface-treated finishes, its self-locking drive ensures stable, sensitive, and reliable tuning across all playing styles.
Crafted with high-grade brass string posts that fit snugly into the housing, this tuning machine provides maximum tuning stability and wear resistance. The innovative stepped M6 flanged washer eliminates the need for stepped headstock drilling by reliably centering the string post and distributing mechanical pressure evenly.
Permanently lubricated with Schaller special grease for maintenance-free operation, the sealed housing preserves longevity. Designed for instruments requiring a 10 mm pin spacing and an 8 mm distance between locating pins and post center, it provides a direct, secure replacement for compatible pin-mount configurations.
