The backbox , also sometimes referred to as the black box , is intended to solve some of the difficulties of free-floating tremolos when playing the guitar. For example, it can be used by users of Floyd Rose systems .

The known difficulties of a Floyd Rose tremolo, namely the immediate detuning when a string breaks and the fact that playing with the heel of the right hand on the ball regularly produces slight detuning, are at least partially eliminated by the backbox.

Inserted into the spring chamber of the tremolo on the back of the guitar , the backbox presses against the tremolo block and thus provides support for the string tension. The resistance is adjustable. This means that the guitar does not immediately go out of tune if the string breaks, and the placing of the ball of the hand is compensated for. Nevertheless, it is still possible to use the tremolo arm to influence the pitch . The lowering of the tone is possible without any restrictions, while raising the tone requires a little more force, as the resistance of the backbox must first be overcome.

If the spring tension in the spring chamber is increased a little more than necessary after the backbox has been installed and the resistance of the backbox is equalized, tuning freely floating tremolo systems is also more comfortable, as the string no longer pulls the tremolo upwards.
