A guitar accessory is an item used to enhance the sound of a guitar. The most common accessories are a CAPO (4 letters), which is a device that clamps onto the neck of the guitar and changes the pitch of the strings; an amp (3 letters), which is an electronic device used to amplify the sound of the guitar; a STRAP (5 letters), which is used to secure the guitar to the player's body; a PICK (4 letters), which is a small piece of plastic or other material used to pluck the strings; and an EBow (4 letters), which is a hand-held device that uses electromagnetic fields to vibrate the strings of the guitar.
