This large tap plate (golpeador) is used by most Spanish flamenco guitar luthiers to protect the guitar top from the player's action without muting sound projection. The adhesive on this golpeador is very sticky. If you do not have experience working to apply this it is advised that you practice on a not so important instrument first, or seek the help of a professional luthier. Removal can be difficult, and finish damage is always possible! Be aware experience to apply a golpeador is required.
