Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine sets an industry benchmark for enclosed tuners, featuring an upgraded 1:18 gear ratio that provides velvety smooth operation and pinpoint tuning precision. Each component is CNC-machined to exact tolerances and precision-fitted within a durable housing for unmatched tuning stability.
Equipped with high-grade brass string posts and permanently lubricated with proprietary Schaller grease, these maintenance-free tuning machines ensure wear-free, long-term performance. The innovative stepped M6 flanged washer centers the string post securely without requiring stepped peghead drilling, effectively eliminating tilt and reducing structural tension.
Engineered for versatility, this tuner seamlessly replaces older M6 models without headstock modifications. Every set includes mounting screws, stepped flanged washers, and hollow mounting bolts required for complete, rock-solid installation on solid headstock configurations.
