Just before a recent gig, I noticed some weird behavior with my Headway EDB-2. The Channel 1 input was making a bit of noise, esp turned below 12 oclock, sometimes would cut out completely if turned down. Not to mention that tweaking it makes a bit of noise. Problem seems to be associated with the gain knob. Channel 2 seems fine. Anybody have this problem before? I went on to play the gig fine once the gain was set to about 2 o'clock and was uneventful otherwise. I guess I may have to send it back but it does have to go overseas doesn't it?
