Locking tuner with locking screw on top of the shaft. Otherwise like the tried and tested Schaller M6 Mini. 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 your strings faster and easier. Only this patented locking system based on the ball socket principle prevents string notching and breakage. 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
