Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine represents the pinnacle of closed-housing tuner design, engineered with a refined 1:18 gear ratio for exceptionally smooth, velvet-like operation and pinpoint tuning precision. Each tuner is manufactured with high-precision CNC machining and high-grade brass posts to deliver optimal stability, wear resistance, and long-lasting durability.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation by eliminating the requirement for a stepped peghead bore while reliably centering the string post. This structural enhancement effectively counteracts tilting torque and alleviates mechanical stress on both the string post and rear mounting screw.
Every sealed tuner unit is permanently lubricated with proprietary Schaller grease, rendering it entirely maintenance-free over its operational life. Designed with a versatile footprint, the M6 180 directly replaces legacy M6 models seamlessly across various solid and slotted headstock configurations.
