I got a Gator rack bag for my IAMP 600 and I think it doesn't allow enough air flow. A couple times the amp has shut down (does not produce sound) but seems to remain on. The preamp lights still light up, but no sound comes out. I reproduced the problem at home once, and when I took the amp out of the bag I noticed it was warmer than I've ever felt it before. Turning the amp off and on again fixes it. Does anyone know if that's how this amp is designed? I emailed the company about it as well, I'm just being impatient and I thought maybe someone here knows. Thanks!
