No operational issues were found. I am selling this because I rarely used it. Everything in the pictures is included. The built-in battery's charging management function has been improved, extending the maximum continuous usage time from the previous 6 hours to 7 hours. The G10T transmitter is compatible with the Relay G10S and Relay G10 guitar wireless systems, as well as the Line 6 Spider V 60, 120, 240, 240HC amps (original and MKII) and Yamaha THR-II. Simply plug the G10TII into your instrument and start playing. It has a built-in rechargeable battery that provides up to 7 hours of playing time, and charging is as simple as plugging it into the input of the G10 or G10S guitar wireless receiver or the compatible amps mentioned above. - Brand: LINE 6 - Model: RELAY G10 - Model: RELAY G10II
