This listing is for an AMP Energy Sound Reactive LED Sign. It illuminates green and is sound reactive. There are two dials in the back; one for lightning pattern and one for sound reactivity. Both work. The frame of the sign has a small chip that has been repaired and is shown in picture 4. This sign is very rare and is the only one I could find on eBay. It would be perfect for your game room. All reasonable offers are welcome! Thanks for visiting Through the Moon Door. Please stay a while and check out our store while you're here! Have a great day!
