Schaller M6 135 Guitar Tuning Machine

The Schaller M6 135 guitar tuning machine delivers exceptional tuning precision and stability with an enhanced 1:18 gear ratio. Designed with high-precision CNC-machined components and a self-locking drive, it provides smooth, sensitive, and reliable tuning adjustments for electric and acoustic guitars.
Crafted with premium brass string posts precision-fitted to the housing, this tuning machine ensures maximum wear resistance and tuning retention. The innovative stepped M6 flanged washer centers the string post reliably without requiring a stepped headstock hole, eliminating tilt torque and taking pressure off the mounting screws.
All enclosed components are permanently lubricated with specialized Schaller grease for completely maintenance-free performance. Featuring identical installation dimensions to its predecessor, the M6 135 serves as an effortless drop-in upgrade or replacement.
