The Fender floating tremolo also features a knob that enables the player to lock, and thus disable, the tremolo mechanism. This facilitates quick retuning in the event of a string breaking, and strives to provide tuning stability similar to a fixed bridge guitar. In practice, the lock doesn't generally achieve as much stability as a fixed bridge, leading some players to replace the mechanism with a fixed bridge and tailpiece. The "floating tremolo" was greatly favored by some surf music bands, particularly for its ability to produce a pronounced and distinctive vibrato on a sustained chord without disturbing the tuning of the guitar. To fully achieve this benefit however, correct setup, as per Fender's recommendations, was essential.
