Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents the continuous evolution of a legendary closed-gear design. Featuring a refined 1:18 gear ratio, it delivers unmatched precision, smooth action, and exceptional tuning stability. High-precision CNC-machined components and solid brass string posts guarantee wear-free performance and reliable operation.
Equipped with the innovative stepped M6 flanged washer, this tuning machine ensures direct center alignment of the string post without requiring stepped headstock boreholes. This engineered design effectively eliminates tilting torque and reduces structural stress on both the post and rear mounting screws.
Permanently lubricated with Schaller special grease for maintenance-free longevity, each unit is built for direct drop-in replacement on standard headstocks. Premium surface finishing and precision-fit internal gearing ensure dependable, velvety-smooth instrument tuning.
