Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets a benchmark for enclosed tuning mechanisms, combining classic heritage with refined modern engineering. Equipped with a precise 1:18 gear ratio, it delivers velvety-smooth action, sensitive adjustments, and dependable tuning stability for discerning players.
Crafted with CNC-machined precision components and high-grade brass posts, each tuner features a self-locking drive and permanent internal lubrication with Schaller specialty grease for maintenance-free operation over years of play.
An innovative stepped M6 flanged washer eliminates tilt torque and simplifies headstock mounting, centering the string post directly through the banjo bolt without requiring stepped headstock drilling.
