Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine delivers outstanding precision and smooth handling with an upgraded 1:18 gear ratio. As an evolution of the legendary enclosed tuner design introduced in 1966, it incorporates state-of-the-art enhancements while preserving its iconic look and feel.
Engineered with CNC-machined components and high-grade brass posts, this tuning machine provides exceptional mechanical stability and wear-free performance. Closed housings feature specialized lifetime lubrication for maintenance-free operation under demanding playing conditions.
Installation is straightforward thanks to the stepped M6 collar washer, which aligns the string post perfectly through the hollow screw without needing a stepped peghead bore. It shares identical mounting dimensions with its predecessor model for easy drop-in replacement.
