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 provides velvety-smooth action and precise tuning control. Every component is CNC-machined to exacting tolerances and treated with a high-grade surface finish for lasting durability and stability.
Equipped with high-grade brass string posts engineered for wear-free performance, the M6 Pin incorporates an innovative stepped flanged washer. This feature reliably centers the string post without requiring a stepped headstock bore, effectively eliminating tilting torque and reducing pressure on internal components.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, this tuner features a 0.39 in (10 mm) pin spacing and an 0.31 in (8 mm) spacing from the pins to the center post, delivering dependable replacement performance and tuning stability.
