tube amp question
So I got this vht pittbull combo and I was just messing with it and I think theres something wrong with it. First off the volume knob on the clean channel is completely off but if I play I can hear myself fine. Secondly, when I switch to the dirty channel it like stays clean but there is distortion in the backround, like I was playing clean and someone else was playing lower then me but playing on a dirty channel. I don't think this is normal.
