Hallstatt Hallstatt Electric Violin CV-210E 4/4 with case I received this from an acquaintance, but I'm selling it because I don't use it. Amplifier and headphones have been tested and are working. No bow included. ☆Product Features☆ ● The body shape is hollow, a silent design, making the natural sound quieter than a regular violin, perfect for practicing at home or at night. ● Equipped with a headphone jack, you can play while adjusting the volume using headphones. ☆Product Specifications☆ Size: 4/4 Power: 9V battery Color: Matte Black Please search for the model number "CV-210E" for other detailed specifications. I do not have knowledge of musical instruments, so I cannot answer specialized questions. This is a used item, Please refrain from purchasing if you are looking for a new-like condition or are very particular. Thank you! Q11-16YT
