Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets the standard for closed tuning mechanisms, combining legendary heritage with modern precision engineering. Featuring an upgraded 1:18 gear ratio, it provides exceptionally smooth action, precise micro-tuning, and robust tuning stability. Each component is CNC-machined to exacting tolerances and permanently lubricated with Schaller special grease for completely maintenance-free operation.
Equipped with solid brass string posts that fit snugly into the housing, this machine head prevents wear and ensures maximum tuning consistency over time. The innovative stepped M6 flanged washer centers the string post reliably via the banjo bolt, eliminating the need for a stepped hole in the headstock and distributing mechanical tension evenly away from the mounting pins and screws.
Designed with a dual-pin mounting configuration spaced 0.4 in (10 mm) center-to-center, the M6 Pin offers seamless installation and direct replacement for compatible guitars. With an 0.3 in (8 mm) spacing from the rear alignment pins to the post center, it ensures clean, stable, and rigid placement on your instrument's headstock.
