2.4GHz digital wireless system with cable tone settings up to 30 feet. - Brand: LINE 6 - Model: RELAY G30 - Type: Wireless System - Number of Channels: 6 - Frequency Band: 2.4GHz - Included Accessories: AC Adapter - Cable Tone Settings: OFF / 15 / 30 feet (0 / 5 / 10 meters) Includes transmitter, receiver, AC adapter (genuine), and a CLASSIC PRO 60cm shield cable (white). Each channel has been tested and confirmed to be working. The receiver has a slight stickiness, but it's not very noticeable, I think. The battery cover of the transmitter tends to not close tightly due to the product's specifications, but this one closes quite well. Thank you for looking.
