Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 features an advanced 1:18 gear ratio that delivers exceptional tuning precision and velvety-smooth operation. All components are CNC-machined and surface-finished to ensure consistent, highly sensitive, and wear-free tuning stability with a self-locking drive.
Equipped with high-grade brass string posts and permanently lubricated with Schaller special grease, these sealed tuners are completely maintenance-free. The innovative stepped M6 flanged washer accurately centers the string post without requiring a stepped peghead bore, eliminating tilting torque and reducing strain on mounting hardware.
Engineered with identical installation dimensions to its predecessor, the M6 135 serves as a direct drop-in replacement without requiring guitar modifications. It includes threaded bushings, flanged washers, and mounting screws for complete and secure installation.
