Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for closed tuners, featuring an upgraded 1:18 gear ratio that provides velvety-smooth action and precise tuning accuracy. Every component is CNC-machined to exacting tolerances and treated with a high-grade surface finish for lasting durability and stability.
Equipped with premium brass string posts fitted directly into the housing, this tuning machine delivers dependable wear resistance and tuning retention. The specialized stepped collar design ensures seamless installation and keeps the string post accurately centered without requiring stepped peghead drilling.
