Line 6 has the worst customer service in the world!!! I also have a defective G10 that wont charge i opened a service ticket and Line 6 replied that i needed to contact a service center near my home which i did but the owner of the store said since i didn't buy the system through his store he is not obligated to give me service!!! DONT BUY THIS SYSTEM THEY ARE CRAP!!! And they are NOT serviceable!!!!
My G10 looses charge in like two minutes after charging for a couple hours, it even displays the green light on the transmitter. But like i said as soon as i plug the transmitter into the guitar the charge last for around a couple of minutes.
