This is an Aria electric acoustic guitar. It doesn't require batteries and can be connected to an amplifier to produce sound. It has a relatively small body, making it recommended for beginners and those with smaller frames. I have adjusted it for ease of playing and confirmed the sound output with an amplifier. Regarding the neck condition, there are no frets that don't produce sound in standard tuning, so I believe there is no extreme warping. As it is a used item, there are signs of use such as scratches, dents, and rust/dulling on the metal parts. No accessories are included. A stand, case, box, and other accessories are not included. Please ask any questions you may have before purchasing. Acoustic guitar, folk guitar, beginner
