Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents precision engineering with an advanced 1:18 gear ratio, delivering ultra-smooth tuning and exceptional pitch stability. Building upon the legendary sealed design first introduced in 1966, this modern iteration incorporates CNC-machined components and high-grade brass string posts engineered for maximum wear resistance.
Featuring the innovative stepped M6 flanged washer, each tuner self-centers reliably without requiring stepped peghead drilling, eliminating tilting torque and reducing mechanical stress on both the post and mounting screw. The self-locking drive and permanently lubricated sealed housing guarantee consistent, maintenance-free performance across diverse playing conditions.
Designed for versatile configurations, the M6 180 serves as a direct drop-in replacement for earlier models while providing superior mechanical feedback. Every tuner is crafted with tight tolerances to ensure stable holding power and precise adjustment across every string change.
