Locking tuners are a type of guitar tuning machine that features a locking mechanism to keep the string in place. This prevents the string from slipping, which can cause the guitar to go out of tune. Locking tuners are considered to be the best type of tuning machine for guitars because they provide the most stability and accuracy.
Locking tuners are especially important for guitars that are used for heavy playing or for playing in live settings. They can also be beneficial for guitars that have a floating bridge, as they can help to prevent the bridge from moving out of place.
