Hello. I have a JTV89 with POD500. I have problems with the guitar when I want to use the battery. Without the battery everything works fine. With the battery I have no sound. The charge indicator indicates a full charge. I connect the guitar with different cables but nothing changes. As soon as I remove the battery, I found the sound. I tested the battery on another machine and it works. I do not know what to do ...
Thank you for your help! Chris (sorry for my bad english)
