Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with an advanced 1:18 gear ratio. All components are CNC-machined to precise tolerances and surface-finished, featuring self-locking drive mechanisms for outstanding stability.
Equipped with high-grade brass posts precision-fitted into the housing, these tuners ensure maximum tuning stability and wear resistance. The innovative stepped M6 flanged washer centers the string post reliably via the hollow screw, preventing tilt and eliminating the need for a stepped peghead bore.
Permanently lubricated with Schaller special grease, these sealed tuning machines offer maintenance-free performance. They serve as a direct replacement for previous closed-housing designs, providing modern mechanical reliability.
