Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine offers exceptional precision and tuning comfort with an upgraded 1:18 gear ratio. All components are CNC-machined and surface-treated, featuring a self-locking mechanism that ensures smooth, responsive, and long-lasting tuning stability.
Equipped with high-grade brass string posts engineered precisely into the housing, these tuners deliver wear-free operation. The stepped M6 flanged washer centers the post reliably without requiring stepped headstock drilling, eliminating tilting torque and protecting the mounting screws.
Sharing identical mounting dimensions with its predecessor model, the M6 135 enables drop-in replacement without instrument modifications. Sealed and permanently lubricated with Schaller special grease, these machine heads remain completely maintenance-free throughout their lifespan.
