Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 Guitar Tuning Machine delivers exceptional tuning accuracy with its precision-engineered 1:18 gear ratio. Designed with CNC-machined components and high-grade brass string posts, this enclosed tuner ensures smooth operation, self-locking drive stability, and lasting wear resistance.
Featuring Schaller's innovative stepped flanged washer, the unit mounts securely and centers the post through the hollow screw without requiring stepped peghead drilling. This design eliminates tilting torque and reduces strain on both the string axis and rear mounting screw.
Permanently lubricated with Schaller special grease for completely maintenance-free performance, the M6 135 maintains identical installation dimensions to its predecessor for hassle-free drop-in replacement.
