Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 tuning machine sets a high standard for enclosed tuners with its refined 1:18 gear ratio, delivering precise, velvety-smooth tuning operation and exceptional tuning stability. All parts are precision CNC-machined and surface-treated, featuring a self-locking drive mechanism to guarantee uniform and sensitive adjustments.
Crafted with premium brass string posts precision-fitted directly into the housing, these tuners ensure long-lasting, wear-free performance. Each enclosed unit is permanently lubricated with Schaller special grease, rendering the system completely maintenance-free over its operating life.
Featuring the innovative stepped M6 flanged washer, the system centers the string post securely through the banjo bolt without requiring stepped peghead drilling. This design eliminates tilting moments and absorbs mechanical stress from both the post and mounting screw, matching the exact mounting dimensions of predecessor models for seamless installation.
