Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 represents precision engineering and refined performance, setting a modern benchmark for enclosed guitar tuning machines. Equipped with an upgraded 1:18 gear ratio, it provides exceptionally smooth, accurate, and stable tuning response across all playing conditions.
Every component is CNC-machined to precise tolerances and finished with premium surface coatings, featuring self-locking drive mechanics and brass string posts tailored directly to the housing for maximum wear resistance. All enclosed tuners are permanently lubricated with Schaller special grease for maintenance-free operation.
Featuring the innovative stepped M6 flanged washer, this tuning machine centers the string post securely over the banjo bolt without requiring a stepped headstock bore. It shares identical mounting dimensions with classic predecessor models, allowing for direct drop-in replacement without instrument modifications.
