Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry benchmark for closed-gear tuners, featuring an upgraded 1:18 gear ratio for exceptionally precise and smooth tuning. Crafted with CNC-machined components and high-grade brass posts, it guarantees maximum tuning stability, wear resistance, and long-lasting performance.
Equipped with an innovative stepped M6 flanged washer, this tuning machine simplifies installation while eliminating tilt torque and relieving pressure from the string post and rear mounting screw. Its permanently lubricated internal gearing ensures completely maintenance-free operation across years of heavy playing.
Designed with identical mounting dimensions to its classic predecessor, the M6 135 serves as a direct, drop-in replacement without requiring headstock modifications. It delivers unrivaled reliability and precision tuning for guitars with solid or slotted headstocks.
