Schaller M6 180 Locking version with knurled nut / locking screw on top of the shaft. Works like a traditional machine head, but the string needn't be "wound up". Instead it is inserted into the cam hole with the clamp screw loosened, locked with the clamp screw and can then be tuned at once. This makes changing strings faster and easier and prevents string notching and breakage. All sealed tuners are lubricated with Schaller special grease for lifetime maintenance-free service. All parts are precision-crafted and surface-finished, the self-locking drive ensures an even, delicate and steady tuning.
All string posts are made of high-grade brass and fitted into the housing with utmost precision, ensuring the best possible tuning accuracy and wear resistance. Gear ratio 1:14
