Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for closed tuners, featuring an upgraded 1:18 gear ratio that delivers velvet-smooth tuning comfort and exceptional precision. High-precision CNC machining across all components paired with a self-locking drive ensures stable and sensitive pitch adjustments.
Equipped with high-grade brass string posts engineered for maximum wear resistance and tuning stability, each unit is permanently lubricated with proprietary Schaller grease for maintenance-free operation. The stepped M6 flanged washer centers the string post reliably through the banjo bolt without requiring a stepped peghead bore.
Designed with a 0.39 in (10 mm) pin spacing and a 0.31 in (8 mm) spacing from pin to post center, this tuner eliminates tilting torque and reduces mechanical stress on the mounting components during string tensioning.
