Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers precise tuning and exceptional stability. Featuring an advanced 1:18 gear ratio, it ensures smooth and accurate adjustments. CNC-machined components and surface-finished parts provide a self-locking mechanism for reliable operation.
High-grade brass posts are precision-fitted into the housing to maximize wear resistance and sustain pitch stability. The stepped M6 flanged washer centers the string post securely through the hollow screw, eliminating tilt and removing stress from mounting screws without requiring stepped headstock drilling.
Permanently lubricated with Schaller special grease, these enclosed tuning machines remain entirely maintenance-free. Designed to match the installation dimensions of original predecessor models, they allow for seamless direct replacement upgrades.
