So I got a G-10 and after using it for one day it would not charge - no matter what I did. Line 6 was good enough to send me a new one as a replacement. The replacement unit worked once - after charging it, I plugged it into a couple different guitars and it worked great (an acosutic and an electric). I put the transmitter back in the charger and in the morning the base was flashing red and the transmitter does not light up at all. It looks like this one is defective, too. I can't return it to Guitar Center because i bought it using loyalty points and they subtract it from the price rather than treating it like a credit, so I'd be screwed out of $90 if I tried to take it back. I am not a happy camper.
