Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine represents the pinnacle of closed tuning technology, featuring an advanced 1:18 gear ratio for velvety smooth, ultra-precise tuning performance. Precision CNC-machined components with a self-locking drive deliver exceptional stability, sensitivity, and wear-free operation.
Engineered with high-grade brass posts fitted seamlessly into the housing, this machine head guarantees maximum tuning stability. The stepped M6 flanged washer ensures effortless centering and mounting without requiring stepped peghead drilling, eliminating tilting moment and relieving stress on both string post and rear fixing screws.
Each closed housing is permanently lubricated with proprietary Schaller special grease, rendering the unit completely maintenance-free. Designed with identical mounting dimensions to its classic predecessor, it allows direct retrofitting and drop-in replacement without instrument modifications.
