Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets the standard for closed tuning systems, offering precision engineering and exceptional tuning comfort. Featuring an advanced 1:18 gear ratio, it provides velvety smooth adjustments and precise tuning accuracy. Every component is CNC-machined and surface-treated, supported by a self-locking drive and permanently lubricated with Schaller special grease for completely maintenance-free operation.
Built with solid brass string posts that are fitted precisely into the housing, this machine head guarantees long-lasting tuning stability and wear-free performance. The innovative stepped M6 flanged collar reliably centers the string post across the 0.39-inch diameter socket without requiring stepped peghead holes. This design eliminates tilting torque and reduces direct mechanical stress on the string post and rear mounting screws.
Designed for versatile installation, the two-pin mounting setup maintains identical housing dimensions to single-pin predecessors with a standard 0.39-inch center-to-center pin distance. Available in various locking and non-locking configurations, it provides secure string retention and flawless performance across electric and acoustic instruments.
