Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers exceptional precision and tuning comfort with an improved 1:18 gear ratio. Designed with CNC-machined components and high-grade brass string posts, it ensures smooth, sensitive, and stable tuning performance for any playing style.
Equipped with an innovative stepped M6 flanged washer, this tuner allows straightforward mounting without requiring a stepped peghead bore. The design reliably centers the string post via the threaded bushing, eliminating tilting torque and reducing mechanical stress on mounting screws.
Built to the standard mounting dimensions of its predecessor, the M6 135 enables seamless replacement without modification. Permanently lubricated with Schaller special grease, each enclosed unit provides durable, wear-free, and maintenance-free operation.
