Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine delivers outstanding precision and tuning comfort with an improved 1:18 gear ratio. Designed with CNC-machined brass string posts and permanently lubricated sealed housing, it ensures smooth operation and maximum tuning stability.
Featuring the innovative stepped M6 flanged washer, this tuner reliably centers the post without requiring a counterbore in the headstock, completely eliminating tilt torque and protecting mechanical components.
Built to the identical mounting dimensions of its classic predecessor, the M6 135 allows direct drop-in replacement without instrument modification and is offered in standard, Locking, and TopLocking configurations.
