Anyone having any issues with battery drain on the THH06 transmitter? I bought 2 units and one seems fine, the other doesn't seem to switch off properly (although it looks like it does). Battery drains in about 8 hours even when switched off. I had it replaced by the shop but the second one seems to be the same.
Anyone got any thoughts? I've raised a support ticket with Line 6 a week ago but haven't had any response.
