Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine combines legendary design with advanced engineering to deliver precision and tuning comfort. Featuring a 1:18 gear ratio, this closed-type tuning machine ensures velvety-smooth operation and precise pitch adjustment. High-precision CNC-machined components with refined surface finishes work alongside a self-locking drive to provide consistent, stable tuning performance.
Crafted with premium brass string posts fitted precisely into the housing, the M6 Pin offers wear-free operation and high tuning stability. The stepped M6 flanged washer centers the string post reliably via the hollow screw, removing the need for a stepped hole in the headstock while eliminating tilt torque and relieving stress on both the post and rear mounting screws.
Permanently lubricated with Schaller special grease, these sealed tuners are completely maintenance-free. Designed with two rear locator pins at a 0.39-inch (10 mm) center-to-center spacing, the M6 Pin shares identical housing dimensions with its single-pin predecessor for seamless upgrades and reliable instrument compatibility.
