Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents precision engineering with an advanced 1:18 gear ratio for smooth, accurate, and stable tuning. Built with high-precision CNC-machined components and premium brass posts fitted directly into the housing, it ensures wear-free operation and exceptional pitch retention.
Featuring an innovative stepped flanged washer, this tuning machine simplifies headstock installation by reliably centering the string post without requiring stepped counterbores. This design eliminates tilting torque and reduces mechanical stress on both the post and mounting screws.
Permanently lubricated with Schaller special grease for completely maintenance-free performance, the M6 180 delivers reliable tuning stability across solid and slotted headstock configurations.
