This is an electric guitar with a built-in amplifier and effects. With this one guitar, you can play through the built-in speaker. You can also connect it to an amplifier and use it as a regular electric guitar. Furthermore, you can enjoy various sound variations by launching the app. You can connect it to your smartphone via Bluetooth and play along. I've only played it for about a week, and all the accessories are included. I think this is the perfect guitar for practicing at home. Please consider purchasing it. The strings are Erixir strings. It will be shipped in its original box.
