Joyo headphone amplifiers are the solution to the age-old problem of how to play electric guitar or bass on the road or even at home, if you need to play quietly, how to practice late at night and how to play into headphones or with your favorite songs. With the JA-03, this is now possible.
You can easily connect this pocket-sized device directly to your guitar, plug in your headphones or speakers from your computer, for example, or perhaps an mp3 or CD player, and you're ready to play.
