Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for enclosed tuners, featuring an advanced 1:18 gear ratio that delivers exceptional precision and smooth, reliable tuning control. Every component is CNC-machined to exacting tolerances and treated with a high-grade surface finish for velvet-like operation and enduring pitch stability.
Equipped with high-grade brass string posts precisely fitted into the housing, this tuning machine provides maximum wear resistance and zero backlash. The innovative stepped M6 flanged washer reliably centers the string post through the banjonut, eliminating tilting torque and protecting both the post and mounting points without requiring stepped headstock drilling.
Permanently lubricated with specialized grease, the sealed housing ensures completely maintenance-free performance. Designed with a dual-pin mounting configuration featuring a 0.39 in center-to-center pin spacing and a 0.31 in pin-to-post distance, it offers seamless integration and steadfast alignment for solid headstocks.
