Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin series sets a high standard for closed guitar tuning machines with its refined 1:18 gear ratio, delivering precise, smooth tuning and exceptional stability. Every component is CNC-machined to exacting tolerances, featuring brass string posts and self-locking drive mechanisms to ensure long-lasting, wear-free performance.
Featuring the innovative stepped M6 flanged collar, this tuning machine aligns the string post reliably through the hollow screw without requiring stepped peghead drilling. This design eliminates tilting moment and reduces mechanical stress on both the shaft and rear mounting points, while sealed lubrication keeps internal components maintenance-free.
Equipped with dual rear mounting pins spaced at 0.39 in (10 mm) center-to-center, the M6 Pin offers a direct retrofit for previous Schaller single-pin housings while maintaining rock-solid headstock placement. High-grade surface finishing and precision engineering ensure superior tone transmission and dependable tuning stability across various playing styles.
