Hi all. This is weird. G10s works fine with all guitars I've got, except my ovation 12 string. Problem is not with g10s, within 2 to 5 mins or so of inserting the transmitter, the guitar low battery light comes on and stops all signal from passing thru. Yes, it's a brand new 12v battery. Even tried a 2nd battery. Any thoughts? I've got nothin.
