Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine continues a legendary standard in precision tuning with an upgraded 1:18 gear ratio for smooth, accurate adjustments. CNC-machined components and high-grade brass posts ensure lasting tuning stability, wear resistance, and sensitive control.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post without requiring a stepped headstock bore. This design eliminates tilting torque and reduces mechanical stress on both the post and rear mounting screws.
Permanently lubricated with Schaller special grease, the sealed housing provides maintenance-free performance. Designed with identical mounting dimensions to its predecessor, it serves as a seamless replacement upgrade for solid or slotted headstock instruments.
