The Schaller M6 135 guitar tuning machine delivers state-of-the-art precision and exceptional tuning stability. Featuring an improved 1:18 gear ratio, this legendary closed tuning machine allows for smooth, sensitive, and accurate adjustments across all musical styles.
Engineered with premium CNC-machined components, each unit incorporates high-grade brass string posts and self-locking drive mechanisms for wear-free performance. The innovative stepped M6 flanged washer reliably centers the string post via the banjo bolt, preventing tilting moment and eliminating headstock stress.
