Schaller M6 180 Guitar Tuning Machine

The Schaller M6 180 guitar tuning machine represents precision engineering with an advanced 1:18 gear ratio, delivering velvet-smooth operation and superior tuning stability. Designed as a modern evolution of the classic closed-back standard introduced in 1966, it features high-precision CNC-machined components and a self-locking drive mechanism for reliable, wear-free performance.
Equipped with an innovative stepped flanged washer, this tuning machine simplifies installation by reliably centering the string post through the banjo bolt without requiring stepped peghead drilling. This design eliminates tilting torque and distributes structural pressure away from both the string post and rear mounting screws.
Crafted with premium high-grade brass posts fitted seamlessly into the housing, all units are permanently lubricated with Schaller special grease for completely maintenance-free longevity. The compact footprint directly replaces predecessor models without requiring headstock modifications.
