Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents an advanced evolution of a legendary standard in enclosed tuners. Designed with a precise 1:18 gear ratio, it ensures velvet-smooth, highly sensitive, and remarkably stable tuning control. Every component is CNC-machined to exacting tolerances and permanently lubricated with Schaller special grease for entirely maintenance-free performance.
Crafted for uncompromising tuning stability and wear resistance, each string post is precisely fitted from premium brass into the durable housing. The unit features an innovative stepped M6 flanged washer with a 0.4 in (10 mm) base diameter that reliably centers the string post via the hollow bolt. This smart design eliminates tilting torque, relieving mechanical stress from both the post and the rear mounting screw without requiring stepped holes in the headstock.
Engineered for versatile configurations, the M6 180 fits standard solid headstock installations as well as locking and staggered setups. Its compact footprint serves as a straightforward direct replacement for legacy M6 units without requiring headstock modifications. Premium materials and German engineering combine to deliver reliable, long-lasting performance for discerning musicians.
