Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 Guitar Tuning Machine sets an exacting standard in closed guitar tuning technology. Built with a refined 1:18 gear ratio, it delivers ultra-smooth rotation and outstanding tuning stability for solid and slotted headstocks.
Every individual component is CNC-machined to precise tolerances and surface-finished for flawless mechanical operation. High-grade brass posts ensure wear-free longevity, while permanently lubricated internal gears eliminate routine maintenance.
Featuring the innovative stepped flanged washer, this tuning machine aligns the string post perfectly over a 0.39-inch (10 mm) diameter bore. This design removes tilting torque and simplifies installation without requiring stepped headstock drilling.
