Ten sound combinations are available to choose from, and they may be selected hands-free by tapping the included foot pedal or by pressing the buttons located on the top of the cajon. Stereo and mono 6.3 mm output jacks allow you to send your signal to any amp or PA system. Adjust your volume as needed with the volume dial. When it’s time for practice or silent playing by yourself, plug your headphones into the cajon through the 3.5 mm headphone jack, and enjoy the rich sounds while not disturbing anyone around you.
