Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for enclosed tuners, featuring an upgraded 1:18 gear ratio that delivers exceptional precision, ultra-smooth operation, and outstanding tuning stability. Every component is CNC-machined to exacting tolerances and treated with a premium surface finish for dependable, wear-free performance.
Equipped with high-grade brass string posts engineered for an exact fit inside the housing, these tuners utilize a self-locking drive mechanism to maintain pitch under demanding playing conditions. Closed housings are permanently lubricated with specialized grease, guaranteeing completely maintenance-free functionality throughout their lifespan.
Installation is streamlined through the innovative stepped collar washer, which reliably centers the string post via the hollow bolt without requiring stepped drilling in the headstock. This structural design eliminates tilting torque and reduces direct mechanical stress on both the post and the rear mounting hardware.
