I had the same problem with mine...ends up it was dirty...I soaked it in gasoline overnight and then powered it up to dry...now it doesnt do that anymore
How did that stuff with the Great White show trial end up...like Im sure everyone here knows that you have to have corrigated foam that is fire retardant for your home studio...and that is what caught fire in that club and ended up being the reason it went up so fast.
I thought if they would have dug deeper they would have blamed it on using faulty building materials...you cant just hang stuff on the wall that will burst into flames...that Club owner was responsible for all those deaths.
