Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine sets a benchmark for enclosed tuners with a refined 1:18 gear ratio that provides ultra-precise, smooth, and dependable tuning action. High-precision CNC-machined components and high-grade brass string posts ensure tight tolerances, maximum tuning stability, and wear-free longevity.
Featuring the innovative stepped M6 flanged washer, this tuner allows straightforward mounting and permanent solid post centering without requiring stepped headstock drilling. This design eliminates tilt moment and significantly reduces mechanical stress on both the string post and rear fixing screw.
Equipped with a self-locking drive and permanently lubricated with specialized grease, the M6 135 is completely maintenance-free. It shares identical footprint dimensions with its predecessor, enabling seamless drop-in replacement on compatible guitar headstocks.
