Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine delivers exceptional tuning precision and smooth operation with its refined 1:18 gear ratio. Designed to build upon the industry standard established by the original closed-type M6, it features high-precision CNC-machined components and a self-locking drive for reliable, backlash-free performance.
Equipped with premium brass string posts fitted accurately into the housing, this machine head guarantees maximum tuning stability and wear resistance. The innovative stepped M6 flanged washer ensures solid, self-centering post alignment through the threaded bushing without requiring a stepped headstock bore, effectively eliminating tilting torque and reducing mounting stress.
Permanently lubricated with Schaller special grease, the sealed housing provides completely maintenance-free longevity. The two-pin mounting configuration matches the housing dimensions of legacy models, making it a dependable choice for modern instrument builds and standard upgrades.
