Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets the standard for closed tuning mechanisms, combining legendary heritage with modern precision engineering. Featuring a refined 1:18 gear ratio, it provides exceptionally smooth, velvet-like action and precise tuning stability.
Every component is precision CNC-machined and surface-finished, featuring a self-locking drive and high-grade brass string posts engineered for wear-free durability. The closed housing comes permanently lubricated with Schaller special grease for entirely maintenance-free operation.
Designed for straightforward installation, the innovative stepped M6 flanged collar reliably centers the string post across a 0.39-inch (10 mm) collar diameter without requiring stepped headstock drilling. This design eliminates tilting torque and relieves mechanical stress on both the post and mounting hardware.
