Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 represents the gold standard in sealed guitar tuning machines, delivering legendary reliability paired with refined engineering. Featuring an advanced 1:18 gear ratio, it ensures precise, velvet-smooth tuning and exceptional pitch stability across all playing styles.
Crafted with precision CNC-machined components and high-grade brass string posts, these tuners provide durable, wear-free performance. The self-locking drive mechanism delivers sensitive and uniform adjustment, while factory-sealed Schaller specialty grease guarantees lifetime maintenance-free operation.
Engineered with the innovative stepped M6 flanged washer, the system centers the string post securely without requiring stepped peghead counterbores, effectively eliminating tilting torque and protecting your instrument. Sharing identical mounting dimensions with its predecessor, it serves as a seamless drop-in replacement.
