Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine delivers outstanding tuning stability and velvety-smooth operation with its refined 1:18 gear ratio. Each component is CNC-machined to precise tolerances and finished with a high-grade surface coating, while high-quality brass string posts ensure wear-free, dependable performance.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation and reliably centers the string post without requiring a stepped headstock bore. The enclosed housing comes permanently lubricated with Schaller special grease for maintenance-free longevity and consistent self-locking action.
Equipped with a dual-pin mounting base featuring a 0.39-inch (10 mm) pin spacing and an 0.31-inch (8 mm) center-to-post distance, the M6 Pin offers direct fitment and flawless retrofitting for compatible solid headstock guitars.
