Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry benchmark for precision and stability, featuring an improved 1:18 gear ratio that provides smooth and accurate tuning. Engineered with high-precision CNC manufacturing and surface finishing, each component operates with a self-locking drive mechanism to maintain pitch reliably.
Crafted with premium brass string posts fitted directly into the enclosed housing, these tuners ensure maximum wear resistance and long-lasting tuning stability. Permanent lubrication with Schaller specialized grease guarantees completely maintenance-free operation under all playing conditions.
Featuring the innovative stepped M6 flanged washer, this tuning machine centers the string post securely through the threaded bushing without requiring stepped peghead drilling. This design eliminates tilting torque and reduces mechanical stress on the post and mounting screws, matching the exact installation dimensions of preceding models for effortless direct replacement.
