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 tuning machine introduced in 1966, this model incorporates refined mechanical enhancements while maintaining its classic design.
Each component is CNC-machined to tight tolerances and surface-finished for smooth, delicate, and stable tuning through a self-locking drive mechanism. Premium brass string posts fit securely within the housing to ensure optimal tuning stability and long-lasting wear resistance.
Equipped with an innovative stepped M6 flanged washer, this tuning machine simplifies installation by reliably centering the string post via the hollow screw, preventing tilt torque and reducing mechanical stress on the post and rear mounting screw.
