Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and tuning comfort with an advanced 1:18 gear ratio. Continuing the legacy of the original sealed tuner, this design incorporates precision CNC-machined components and high-grade brass string posts engineered for maximum tuning stability and wear resistance.
Featuring the innovative stepped M6 flanged washer, this tuner allows smooth installation and solid shaft centering without requiring a stepped peghead bore. The self-locking drive and permanently lubricated sealed housing guarantee smooth, sensitive, and completely maintenance-free operation.
Designed with identical mounting dimensions to its predecessor, the M6 135 serves as a direct drop-in replacement. Every component is surface-finished to exacting standards, eliminating tilt torque and protecting string posts under tension.
