Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine offers precision engineering and smooth tuning stability with an upgraded 1:18 gear ratio. All components are CNC-machined to exacting tolerances, featuring surface-treated finishes and self-locking drive mechanisms that ensure consistent, delicate adjustment.
Crafted with premium brass string posts fitted precisely into the housing, this tuning machine provides maximum wear resistance and tuning accuracy. The stepped collar design centers the post securely through the banjo bolt, eliminating tilting moment and relieving stress on the peghead and mounting assembly.
Equipped with permanent internal lubrication via specialized Schaller grease, each enclosed unit operates maintenance-free. Dual-pin indexing ensures reliable positioning with an exact 0.39-inch pin-to-pin spacing for solid mounting.
