Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and smooth operation with an improved 1:18 gear ratio. Designed as an evolution of the legendary original sealed tuner, all components are CNC-machined with high precision and surface-treated for maximum wear resistance and performance.
Featuring high-grade brass string posts engineered for optimal tuning stability, each unit is permanently lubricated with proprietary Schaller grease for completely maintenance-free reliability. The innovative stepped M6 flanged washer ensures precise post centering over the threaded bushing, eliminating tilting torque without requiring stepped headstock boreholes.
Compatible with standard guitar headstocks, this direct-replacement tuner offers effortless installation and rock-solid mechanical stability. Precision engineering guarantees smooth, sensitive adjustments for demanding musicians.
