Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine represents precision engineering and refined performance, setting the standard for enclosed tuners. Designed with an advanced 1:18 gear ratio, it delivers velvety-smooth, highly accurate tuning and exceptional pitch stability. Every component is CNC-machined to exacting tolerances, featuring brass string posts that resist wear and seat perfectly within the housing.
Featuring the innovative stepped M6 flanged collar, this tuning machine simplifies installation while ensuring permanently solid centering of the string post. The stepped base eliminates tilting movement and reduces mechanical stress on both the post and mounting screws, removing the need for stepped peghead holes. High-grade surface finishing and a self-locking drive guarantee consistent, delicate adjustment across diverse playing conditions.
Permanently lubricated with Schaller special grease, the enclosed mechanism operates completely maintenance-free over its lifespan. The M6 90 maintains identical installation dimensions to its predecessor for direct, modification-free retrofitting.
