They typically feature a pin or retaining mechanism that clamps the strings in place, preventing them from slipping when you’re playing. Locking tuners work just like regular tuning machines but they are designed to improve tuning stability and make string changes much faster. Locking tuners provide a mechanism that negates the need for several winds on the string post by using a system that latches onto the string, only needing a twist of a half turn to fully make contact with the string and ensure stable tuning. \u003cbr\u003e\u003cbr\u003eLocking tuners are great for players who use tremolos or who frequently change tunings. They are also great for players who want to make string changes quickly without having to worry about winding strings around posts. \u003cbr\u003e","published_at":"2020-07-25T09:55:06-04:00","sort_order":"best-selling","template_suffix":"","disjunctive":false,"rules":[{"column":"tag","relation":"equals","condition":"Parts\/Guitar Locking Tuners"}],"published_scope":"web","image":{"created_at":"2023-03-31T12:43:14-04:00","alt":null,"width":1500,"height":1347,"src":"\/\/sporthitech.com\/cdn\/shop\/collections\/Chrome_6L_Beauty_J-1500.jpg?v=1680280995"}}]
