A cajón is normally a box-shaped percussion instrument originally from Peru, played by slapping the front (usually called the tapa or head face) or rear faces with the hands, fingers, or sometimes various implements such as brushes, mallets, or sticks.
This particular bespoke order also has a double snare near the top. The snares are 20 strand 7" long and adjustable. The inside surface of the beat side is heavily varnished to give the snares a more crisp sound.
Made from hand selected Chinese hardwood ply (for the gorgeous grain) 18mm thick for the top, bottom and sides whilst the beat face and rear are made from 4mm UK birch ply.
