Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine offers precision engineering and tuning comfort with an advanced 1:18 gear ratio. Designed with CNC-machined components and high-grade brass string posts, this enclosed tuner delivers smooth, velvet-like action and exceptional tuning stability.
Equipped with Schaller's innovative stepped flanged washer, the mechanism centers the string post securely through the threaded bushing without requiring stepped headstock drilling. This design eliminates tilting torque and minimizes mechanical stress on both the post and mounting screws.
Featuring permanently lubricated internal gears with proprietary Schaller grease, this maintenance-free tuner matches the exact installation dimensions of its predecessor for hassle-free replacement on compatible instruments.
