Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine combines legendary design with modern precision engineering. Built with a refined 1:18 gear ratio, it ensures precise, velvety smooth tuning action along with exceptional tuning stability. All components are CNC-machined and surface-finished to deliver reliable, self-locking drive performance.
Crafted with premium brass string posts precisely fitted into the housing, this tuning machine provides maximum wear resistance and longevity. The innovative stepped M6 flanged washer centers the string post securely over the hollow screw, removing tilt torque and eliminating the need for stepped peghead drilling.
All enclosed M6 Pin tuning machines come permanently lubricated with Schaller special grease for completely maintenance-free operation. Featuring dual rear locating pins with a 0.39 in pin spacing and a 0.31 in distance from pins to the center of the post, it offers solid alignment and effortless installation.
