I own a Bag End 4x10 8ohm cab that can handle 400 watts. I also own a BP200 bass pedal and a carvin 2000 watt 2 channel power amp. As of this morning, my rig is very quiet. There are no other signs of damage. I used to not be able to crank up the volume on my pedal all the way up and the volume of the power amp past 2/3s of the way before it got so loud the "clip" light came on. It was very loud at this level. Now I can turn all knobs up full bast and the volume only seems half of what it used to be. The sound itself other than being quiet is fine. What the heck is going on here?
