Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers outstanding tuning precision and smooth operation with its refined 1:18 gear ratio. All components are CNC-machined to exacting tolerances and surface-finished, featuring a self-locking drive mechanism that ensures consistent, responsive, and stable tuning performance.
Equipped with high-grade brass string posts engineered for wear-free durability, each unit incorporates the innovative stepped M6 flanged washer with a 0.39-inch diameter base. This design centers the string post securely through the banjo bolt, eliminating tilt torque and protecting both the string post and mounting components without requiring stepped peghead drilling.
Designed for lifetime maintenance-free performance, every closed housing is permanently lubricated with Schaller special grease. The dual-pin base design maintains exact vintage housing specifications with 0.39-inch pin-to-pin spacing for seamless retrofits on compatible solid headstocks.
