Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers high-precision instrument tuning with an advanced 1:18 gear ratio for smooth, accurate adjustments. Setting the global standard for closed tuning machines since 1966, this updated design offers enhanced functionality and lasting performance without sacrificing its legendary identity.
Crafted with CNC-machined components and precision-fitted brass string posts, these tuners feature a self-locking drive mechanism that guarantees maximum tuning stability and wear-free operation. Permanent internal lubrication with Schaller special grease ensures completely maintenance-free longevity.
Featuring the innovative stepped M6 flanged collar with a 0.39 in diameter, the string post centers securely through the banjo bolt without requiring stepped headstock drilling. This design eliminates tilting torque and relieves mechanical stress from both the post and rear mounting screw.
