Schaller M6 90 Guitar Tuning Machine
The Schaller M6 90 guitar tuning machine represents high-precision engineering and exceptional tuning comfort. Featuring a refined 1:18 gear ratio, it delivers ultra-smooth, accurate, and reliable operation. All components are CNC-machined with high precision and surface-finished to ensure consistent, stable tuning with self-locking drive mechanics.
Crafted with premium brass string posts precision-fitted into the housing, these tuners provide maximum tuning stability and long-lasting wear resistance. The innovative stepped M6 flanged washer centers the string post securely via the hollow screw, removing pressure from both the post and mounting screw without requiring stepped peghead drilling.
Each closed machine head is permanently lubricated with Schaller special grease, making the internal mechanics completely maintenance-free. Designed with identical mounting dimensions to its classic predecessor, the M6 90 allows for seamless direct replacement and straightforward installation.
