Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets the standard for closed-type tuning machines, featuring a refined 1:18 gear ratio for velvety smooth, high-precision tuning. Each component is CNC-machined to exact tolerances and surface-finished, utilizing a self-locking drive mechanism to deliver reliable stability and sensitive adjustment.
Equipped with high-grade brass posts precision-fitted into the housing, these tuners ensure zero wear and maximum tuning stability. The innovative stepped M6 flanged washer centers the string post securely through the banjo bolt, eliminating tilt torque and protecting against excessive lateral pressure without requiring stepped peghead holes.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, these tuners feature a dual-pin configuration with a 0.39 in center-to-center pin spacing and an 0.31 in distance from pins to string post center.
