Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets an industry benchmark for precision and stability, featuring an improved 1:18 gear ratio for smooth and exact tuning control. Each component is CNC-machined to exacting tolerances and surface-treated to guarantee long-lasting, self-locking operation without backlash.
Equipped with high-grade brass string posts engineered for wear-free durability, this tuning machine incorporates the innovative stepped M6 flanged washer. This design reliably centers the string post via the banjo bolt with a 0.39-inch diameter base, eliminating tilting moments and avoiding the need for stepped peghead holes.
Permanently lubricated with Schaller special grease, the sealed housing provides completely maintenance-free performance. Dual rear locating pins ensure rock-solid mechanical positioning and streamlined headstock installation across diverse configuration options.
