LINE6 RELAY G10S Wireless System The firmware has been updated to the latest version. I used the transmitter, G10TⅡ, in a two-transmitter setup at live houses several times, but I'm selling it because I switched to the G50. I purchased it new in October 2019. I think it's fine for personal hobby use. If you're doing a long solo live performance, I recommend purchasing a separate 10TⅡ transmitter and using the 10T as a backup. Velcro is attached to the back. The adapter and G10TⅡ are not included as they were listed separately. I confirmed that it works without any problems at home. Everything in the photos is included. Please note that this is a used item, so no claims or returns are accepted. Thank you for looking. Line 6 Guitar Bass
