Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 series sets a high standard for enclosed guitar tuning machines, offering an improved 1:18 gear ratio for exceptionally precise and smooth tuning comfort. Drawing on decades of classic design since 1966, this updated model integrates modern innovations while preserving its renowned legacy.
All components are CNC-machined to exacting tolerances, finely finished, and equipped with a self-locking drive that guarantees uniform, delicate, and stable tuning. The high-grade brass string posts are fitted directly into the housing, ensuring superior tuning stability and wear-free performance under regular string tension.
Featuring Schaller's innovative stepped collar washer with a 0.39 in diameter, the M6 180 reliably centers the string post via the hollow bolt without requiring a stepped headstock bore. Permanently lubricated with Schaller special grease, each enclosed unit provides long-term, maintenance-free reliability.
