Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin series sets a standard for closed tuning machines, featuring a precise 1:18 gear ratio for smooth, velvety tuning and exceptional pitch stability. Every component is CNC-machined with high accuracy and surface-finished, supported by a self-locking drive and permanent Schaller special grease lubrication for maintenance-free operation.
Equipped with the innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post via the banjo bolt. This intelligent design eliminates tilting torque, relieves stress from both the post and rear mounting screw, and eliminates the need for a stepped peghead bore.
Crafted with premium high-grade brass string posts fitted seamlessly into the housing, the M6 Pin ensures maximum tuning stability and long-lasting, wear-free performance across diverse playing styles and instrument configurations.
