Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents precision engineering with an advanced 1:18 gear ratio, delivering ultra-smooth operation and unmatched tuning stability. Designed as a modern evolution of the classic closed-back standard introduced in 1966, this model incorporates refined mechanical components for flawless performance.
Crafted with CNC-machined components and premium brass string posts, the internal mechanism is permanently lubricated with specialized Schaller grease to ensure completely maintenance-free operation. The self-locking drive delivers sensitive and rock-solid adjustments across diverse playing conditions.
Featuring the innovative stepped M6 flanged washer, this tuner centers the string post securely through the threaded bushing without requiring stepped peghead drilling. This design eliminates tilting torque and reduces mechanical stress on both the shaft and mounting screws.
