Schaller M6 Pin Guitar Tuning Machine
The Schaller M6 Pin guitar tuning machine sets a benchmark for closed-type tuning mechanisms, combining classic heritage with refined engineering. Featuring an upgraded 1:18 gear ratio, it delivers ultra-precise, smooth, and stable tuning performance. All components are precision CNC-machined and surface-treated, utilizing a self-locking drive to ensure reliable pitch retention and effortless operation.
Crafted with premium brass string posts that fit snugly into the housing, this machine head minimizes wear while ensuring maximum stability. The innovative stepped M6 flanged washer centers the string post securely without requiring stepped peghead counterbores, effectively eliminating tilting torque and reducing mechanical stress on the mounting components. Permanent lubrication with Schaller specialty grease ensures completely maintenance-free functionality.
Designed with a modern two-pin rear mounting configuration with a 0.39-inch pin spacing, it provides a secure drop-in fit for compatible instruments. The robust construction and fine-ratio gearing make it an essential upgrade for musicians demanding professional tuning accuracy and road-ready durability.
