I just got my x2 wireless in the mail yesterday, so I decided to try it out today at a live gig. My band was playing in front on 5000+ people on a massive stage so I thought it would be a good opportunity to use it. She worked like a dream for the first half of the set (about an hour). Then I swaped out my P bass for a Stingray, and the Stingray sounded great too, except the wireless stopped working after the first song. It wasn't the battery, because after the show I looked at both the transmitter and the receiver and both had a good bit of life left. The signal sort of went in and out for a second, then died on me completely. Has this happened to anyone before?
