A wood lip plate can have a stengthening effect on the sound of the flute but it also produces a softer sound that blends superbly with others in the woodwind section. 

This replacement stopper transforms your cork assembly into an adjustable one, giving you the new ability to boost your lower and upper octaves.

The presence of a wave on the headjoint strengthens the sound of the piccolo. There is often a preference for having a little resistance for your bottom lip to rest against. 

This is not purely for aesthetic purposes. As beautiful as this wood looks it gives a new depth to the sound of a headjoint.
