Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine offers exceptional precision and tuning comfort with an upgraded 1:18 gear ratio. Designed with CNC-machined components and high-grade brass posts, it provides velvety-smooth action, rock-solid tuning stability, and wear-free performance for solid headstocks.
Featuring the innovative stepped M6 flanged washer, this tuner simplifies installation by reliably centering the string post directly via the banjo bolt. This eliminates the need for step-drilling into the headplate while effectively taking pressure off the post and mounting points to reduce tilting torque.
All enclosed internal components are permanently lubricated with Schaller special grease for completely maintenance-free operation over a lifetime of play. Built to the highest standards, the M6 series continues setting the benchmark for precision instrument hardware.
