I previously purchased this amplifier used and have confirmed that it produces sound. It has active pickups, and there are no battery leaks. The neck is almost straight and does not hinder playability. There are scratches on the surface of the body, but no other deep scratches. The condition is good, but it is still a used item, so please refrain from purchasing if you are overly concerned. I will respond to any questions in the comments.
