Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents high-precision engineering with an advanced 1:18 gear ratio, delivering ultra-smooth and precise tuning performance. All components are CNC-machined to exact tolerances and permanently lubricated with Schaller special grease for maintenance-free operation and exceptional durability.
Equipped with high-grade brass posts precision-fitted into the housing, these tuners provide maximum tuning stability and wear resistance. The self-locking drive mechanism ensures consistent, sensitive adjustments while maintaining absolute pitch integrity across playing sessions.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post without requiring stepped headstock drilling. This design eliminates tilting torque and reduces mechanical stress on both the post and rear mounting screws.
