Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 sets the standard for closed tuning machines, engineered with a precise 1:18 gear ratio for exceptionally smooth and accurate tuning. Each component is CNC-machined and finished to deliver velvet-smooth operation, sensitive response, and steadfast tuning stability.
Crafted with premium brass string posts and permanently lubricated with Schaller special grease, these maintenance-free tuning machines are built for maximum longevity and wear resistance. The self-locking drive ensures unwavering stability across a wide variety of playing styles.
Featuring the innovative stepped M6 flanged washer, installation is simplified while centering the string post directly through the banjo bolt without requiring a stepped headstock bore. This intelligent design eliminates tilting torque and reduces mechanical strain on both the post and mounting screw.
