This is a set including the Line6 Relay G30 transmitter (bodypack), receiver, AC adapter for the receiver (9V, center negative), and a 60cm cable (CLASSIC PRO). The transmitter's battery cover fits relatively securely. Also, there is no stickiness on the receiver's exterior. There are no particularly noticeable scratches, and I think it's in relatively good condition. However, the belt clip on the bodypack is missing. I have confirmed communication and sound output on each channel. Thank you. - Brand: LINE 6 - Model: RELAY G30 - Type: Digital Wireless System - Frequency Band: 2.4GHz - Number of Channels: 6 - Included Accessories: AC adapter, 60cm shielded cable - Maximum Distance: 30 feet (approx. 9 meters) Thank you for looking.
