I recently bought my Bugera amp through zzounds.com. i noticed , like a few others i saw here, about the amp having an led issue , where the orange around the volume knob turned red, and there was nothing in the manual about it whatsoever. Here is what i figured out.. maybe it will help. I at first thought it was maybe a clipping register, however, noticed no issue in sound quality. The amp is 1000 watts , and i made several calls trying to get customer service, on the amp through Bugera/Berhinger. So i played a gig out (my first one with this powerhouse little combo) and I noticed, that no matter how hard i played or how loud i got, it never showed up a red light on my amp. My thought now, is that these may be another issues entirely. I was on stage and my amp was the only thing pulling power through the plug in /circuit on my side. I think this red light showing up, is if the power supply isnt strong enough to support the amp drain. And it redlights to let you know it hasnt got enough juice to maintain, the amp draw. I had no red light flash, not even once in the venue. Maybe this will help others out..
