Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents an evolution of the iconic closed tuner design first introduced in 1966. Featuring an advanced 1:18 gear ratio, it delivers ultra-smooth operation, precise adjustments, and exceptional tuning stability. Every component is CNC-machined to precise tolerances and finished for long-lasting, frictionless performance.
Equipped with premium brass string posts precisely fitted into the housing, the M6 180 eliminates wear and ensures consistent string tension. The innovative stepped M6 flanged collar reliably centers the string post via the hollow bolt, eliminating tilting moment and removing stress from both the post and rear mounting screw without requiring a counterbore in the headstock.
Permanently lubricated with Schaller special grease, these sealed tuners remain entirely maintenance-free over years of performance. The M6 180 is engineered as a direct replacement for previous models, offering modern functionality and flawless intonation retention across all configurations.
