Schaller M6 135 Guitar Tuning Machine
The Schaller M6 135 guitar tuning machine sets an industry standard for closed-type tuners, delivering unmatched tuning accuracy and smooth performance. Engineered with a precise 1:18 gear ratio, every component is CNC-machined and surface-treated to guarantee smooth, sensitive, and stable tuning through its self-locking drive mechanism.
Crafted with premium brass string posts fitted directly into the housing, this tuning machine provides maximum wear resistance and rock-solid pitch stability. The innovative stepped M6 flanged washer centers the string post securely via the hollow screw, eliminating tilting torque and protecting against excessive mechanical pressure without requiring stepped headstock holes.
Permanently lubricated with Schaller special grease for completely maintenance-free operation, the M6 135 features identical mounting dimensions to its predecessor for direct replacement without instrument modification. Each unit combines legendary durability with refined engineering to elevate your instrument's tuning reliability.
