Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 guitar tuning machine delivers outstanding precision and tuning comfort with an upgraded 1:18 gear ratio. Continuing the legacy of the original closed-housing tuner introduced in 1966, this model incorporates refined mechanics and modern engineering improvements without compromising its iconic design.
Each component is CNC-machined to exact tolerances and finished to ensure velvet-smooth operation and lasting tuning stability. The brass string posts are precisely fitted into the housing, while closed internal gears are permanently lubricated with premium Schaller grease for entirely maintenance-free performance.
An innovative stepped M6 flanged washer reliably centers the string post through the threaded bushing without requiring a stepped peghead bore. This design eliminates tilting torque and takes mechanical strain off both the post and mounting screw, ensuring direct drop-in replacement on standard headstocks.
