Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine sets an industry benchmark for enclosed tuners, combining legendary heritage with state-of-the-art precision. Engineered with a refined 1:18 gear ratio, it delivers ultra-smooth operation, highly sensitive response, and uncompromising tuning stability. Every internal component is CNC-machined to exact tolerances and permanently lubricated with Schaller special grease for maintenance-free performance.
Featuring high-grade brass string posts meticulously fitted into the housing, this tuning machine provides maximum wear resistance and sustained pitch accuracy. The self-locking drive ensures consistent performance across various string gauges and playing styles. The innovative stepped M6 flanged collar centers the post securely through the banjo bolt, eliminating tipping moments and surface stress without requiring stepped headstock drilling.
Designed for straightforward retrofitting, the dual-pin base matches standard Schaller spacing while providing a firm, twist-resistant mount on the rear of your headstock. Precision engineering and durable metal construction make the M6 Pin a dependable choice for exacting musicians, custom builders, and professional repair shops alike.
