Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets an industry benchmark for closed tuners, featuring an upgraded 1:18 gear ratio that delivers exceptional tuning precision and ultra-smooth operation. Each component is CNC-machined with meticulous tolerances and surface-treated to guarantee consistent, backlash-free performance.
Equipped with high-grade brass posts carefully fitted into the housing, this tuning machine provides maximum tuning stability and wear resistance over extended use. The self-locking gear design maintains accurate pitch under demanding playing conditions, while factory-sealed lubrication with Schaller proprietary grease ensures completely maintenance-free operation.
Installation is streamlined via the innovative stepped M6 flanged washer, measuring 0.4 in (10 mm) in diameter, which centers the string post through the banjo bolt without requiring a stepped headstock bore. This specialized design eliminates tilting torque and relieves mechanical stress from both the post and rear mounting assembly.
