Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers outstanding tuning stability and velvety-smooth operation with its advanced 1:18 gear ratio. Every component is precision CNC-machined and surface-finished, featuring high-grade brass string posts engineered for maximum wear resistance.
Equipped with an innovative stepped M6 flanged washer, this tuner reliably centers the string post via the banjo bolt and eliminates tilting moments, safeguarding the mechanism and extending its operational lifespan without requiring stepped headstock drilling.
Permanently lubricated with Schaller special grease for completely maintenance-free performance, the sealed housing features a dual-pin configuration with a 0.39 in center-to-center pin spacing for solid and secure headstock mounting.
