Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers exceptional tuning precision and stability with an upgraded 1:18 gear ratio. CNC-machined to exacting tolerances, every component is surface-treated and features a self-locking drive mechanism for smooth, sensitive, and reliable operation. High-grade brass posts are precisely fitted into the housing to guarantee maximum wear resistance and tuning retention.
An innovative stepped M6 flanged washer streamlines installation and ensures permanent centering of the string post via the hollow bolt, eliminating the need for a stepped headstock borehole. This design removes tilting torque and relieves mechanical stress from both the post and the rear mounting screw. Permanently lubricated with Schaller special grease, the sealed housing provides completely maintenance-free performance.
Designed with standard mounting dimensions identical to its predecessor, the M6 135 serves as a direct drop-in replacement without requiring headstock modifications. Premium materials and robust German engineering make these tuners an ideal upgrade for professional musicians seeking uncompromising reliability and smooth adjustments.
