Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and tuning comfort with an advanced 1:18 gear ratio. As the modern evolution of the classic closed tuner standard first established in 1966, this model incorporates refined CNC-machined components and high-grade brass string posts engineered for velvet-smooth operation, superior tuning stability, and exceptional wear resistance.
Featuring the innovative stepped M6 flanged washer, this tuner eliminates tilting torque and relieves pressure from both the post and mounting screw, ensuring reliable axial centering without requiring stepped headstock drilling. High-precision manufacturing and self-locking drive mechanics provide fine-touch tuning and lasting performance.
Each unit comes permanently lubricated with proprietary Schaller grease for entirely maintenance-free longevity. Designed to fit standard setups seamlessly, it serves as a direct upgrade or replacement for precision-demanding electric and acoustic guitars.
