LINE 6 RELAY G30 wireless system. The receiver's body side may be slightly sticky, which could be due to the nature of the product. There are no issues with its use. Operation has been confirmed. I have inserted unused AA batteries to confirm operation. The battery cover, which is a common issue with this product, is not broken. However, it feels a bit flimsy, so I used Velcro tape to secure it when I used it. The box, adapter, cables, and all other accessories are included. Everything in the photos is included. As a bonus, I will include a new ESP holder. Since this is a used item, there is some wear and tear, so please refrain from purchasing if you are sensitive to such things. Thank you for your understanding. Please refrain from purchasing if you are sensitive to used items. Thank you for your consideration.
