Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 series guitar tuning machine sets an industry standard for enclosed tuners, featuring an upgraded 1:18 gear ratio for velvety smooth, precise tuning. Each component is CNC-machined to exacting tolerances and permanently lubricated with Schaller special grease for maintenance-free performance.
Equipped with high-grade brass string posts engineered for maximum tuning stability, this tuner incorporates a stepped M6 flanged washer with a 0.39 in diameter. This innovative design centers the string post securely via the threaded bushing, eliminating tilting moments without requiring stepped headstock drilling.
Designed to directly replace legacy M6 models without headstock modification, this precision tuner delivers reliable, backlash-free performance across solid and slotted headstocks.
