I always take really good care of my gear and up until now id never had a problem with it. I figured id explain my problem to see if any of you guys had run into it. Im running my ampeg b4r bridged at 1000 watts into m ampeg 6x10hlf. I know this cab isnt rated at 1000 watts but the cab isnt being the problem, the head is. It keeps peaking out with the gain and volume halfway up. Lately it keeps going into mute mode while im playing decently loud. Anyone have any idea before i drop it off at the amp store for it to sit for 6 monthes before its repaired?
