Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin tuning machine sets a high standard for enclosed guitar tuners, featuring an upgraded 1:18 gear ratio for smooth, precise, and dependable tuning comfort. Built on decades of proven German engineering, it delivers exceptional stability and refined performance for modern instruments.
Every component is precision CNC-machined and surface-finished, utilizing high-grade brass posts fitted into the housing for maximum tuning stability and wear resistance. The self-locking internal drive mechanism and permanent factory lubrication ensure consistent, maintenance-free operation.
Equipped with an innovative stepped flanged collar with a 0.39 in (10 mm) base diameter, this design reliably centers the string post via the hollow bolt without requiring a stepped peghead bore. This construction eliminates tilting torque and protects both the post and mounting points for extended longevity.
