Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine sets a benchmark for enclosed tuning mechanisms, combining classic heritage with refined engineering. Featuring an advanced 1:18 gear ratio, it ensures precise, velvet-smooth tuning and exceptional tuning stability. Each component is CNC-machined to exacting tolerances and surface-finished for consistent performance.
Equipped with high-grade brass posts engineered directly into the housing, the M6 180 offers wear-free operation and solid structural alignment. The innovative stepped M6 flanged washer centers the string post securely via the banjonut, eliminating tilting torque and removing the need for a stepped peghead bore.
Permanently lubricated with Schaller special grease, these sealed tuners are completely maintenance-free. Designed for direct replacement of previous M6 models without headstock modifications, they deliver professional-grade durability and tuning comfort.
