Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and tuning comfort with an improved 1:18 gear ratio. All components are CNC-machined to exacting tolerances, surface-finished, and permanently lubricated with Schaller special grease for maintenance-free operation and smooth performance.
Equipped with high-grade brass posts engineered precisely into the housing, these tuners ensure optimal tuning stability and zero wear. The innovative stepped M6 flanged washer centers the string post securely over the banjo bolt without requiring a stepped peghead bore, eliminating tilting torque and reducing pressure on the mounting screws.
Featuring identical installation dimensions to its predecessor, the M6 135 serves as a direct drop-in replacement without instrument modifications. Each set includes banjo bolts, stepped flanged washers, and mounting screws for straightforward installation.
