You could be right, I haven't thought about over driving the input. I'm setting the gain how you would set gain on a mixer or really anything.
I don't think its the EQ. I switched cabs with the same EQ, no fuzzy noise from it and sounds exactly as I want.
But I do really appreciate all the info thus far. Keep it coming, cause this cab sounds killer and should perform just fine with the low end.
Ok now we are getting some where. Have you A/B'ed the cab with another cab with all the same settings? If the actuall distortion is coming from the cab at low volumes, then you may have a fried voice coil.
