What is wrong with my cab? I have a SWR workingman's 4x10 that i got used maybe six months ago, and i've noticed recently that there is major distortion. Maybe this problem has existed all along, except i'm just playing louder now (larger venues). I have a GK 700 that puts out 380 watts, and I can't use all the power because the cab starts distorting. Is it because it's a 4x10, or because it's a workingman's? I'm considering trading this p.o.s. cab in and getting something more powerful by GK or a 1 x 15. HELP A BROTHER OUT!!!! Thanks in advance.
