The term 'Guitar Adjuncts' refers to accessories used to enhance the sound of a guitar. One such accessory is a capo, which is a device that clamps onto the neck of a guitar and shortens the strings, allowing the guitarist to play in different keys without having to change the tuning. A capo is typically made of metal or plastic and is used to raise the pitch of the strings, allowing the guitarist to play chords higher up the fretboard.
