Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets high standards for closed tuning mechanics, featuring a refined 1:18 gear ratio that provides precise and velvety smooth tuning performance. Precision CNC-machined components and surface-finished parts work alongside a self-locking drive to deliver stable, responsive tuning across all playing styles.
Constructed with high-grade brass string posts engineered specifically for minimal wear, this tuning machine ensures long-lasting stability and flawless operation. The innovative stepped M6 collar washer with a 0.4 in diameter reliably centers the string post without requiring a stepped headstock bore, effectively eliminating tilting moments and reducing mechanical stress.
Permanently lubricated with Schaller special grease for completely maintenance-free performance, each unit is engineered for straightforward installation with its dual-pin mounting system featuring a 0.4 in pin-to-pin distance. Mounting hardware including banjos, washers, and M2.2 x 9.5 screws are included for seamless setup.
