Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine delivers outstanding precision and tuning stability with an improved 1:18 gear ratio. CNC-machined components with premium surface finishes and high-grade brass posts ensure smooth, wear-free, and sensitive operation across all tuning applications.
Featuring the innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post via the banjo bolt. This eliminates tilting torque, relieves stress from the mounting screw and string post, and removes the need for step-drilling in the headstock.
Built with closed-housing construction permanently lubricated with Schaller special grease, the M6 135 requires zero maintenance. It shares identical mounting dimensions with its predecessor model, allowing seamless drop-in replacement without instrument modifications.
