Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine features a precise 1:18 gear ratio that ensures smooth and accurate tuning stability. Built with CNC-machined components and high-grade brass string posts, it provides dependable performance and wear-free operation across demanding playing conditions.
Equipped with an innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post without requiring a stepped peghead bore. This design eliminates tilting torque and reduces mechanical stress on both the post and mounting screws.
Permanently lubricated with Schaller special grease for maintenance-free longevity, the M6 135 shares identical installation dimensions with its predecessor model, allowing seamless drop-in replacement without guitar modifications.
