Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine delivers outstanding precision and smooth tuning comfort with an optimized 1:18 gear ratio. As a modern evolution of the classic closed tuning machine introduced in 1966, it incorporates state-of-the-art enhancements while preserving its iconic aesthetic and renowned reliability.
Precision CNC-machined components and surface-finished brass string posts ensure wear-free longevity, exceptional tuning stability, and velvety action. Each enclosed tuner is permanently lubricated with Schaller special grease for completely maintenance-free operation and long-term performance.
The innovative stepped M6 flanged washer centers the string post securely over the hollow screw, preventing tilt and reducing strain on both the post and mounting screw. Designed with identical mounting dimensions to its predecessor, it allows for direct drop-in replacement on compatible guitar headstocks.
