My band was recording when this happened, so I am attaching an edited mp3. This is after a couple of hours of playing, and it was a hot day. About 5 minutes into the song, I start to hear crackling static. (the clip starts at that point). A few seconds later, I lose a lot, but not all, power and the sound is thin and distorted. I edited out the rest of the song and then there is some bass by itself to try and hear what is going on, at 45 seconds in. I change batteries - it's not that. And at about 1:05, play with the new battery. I start out soft, and there is no problem, but when I turn up, the problem is there again. After giving the rig a few days to mellow out, I tried it again just now at full volume and everything was fine. Can anyone diagnose from the description / clip what happened?
