I have an AS100D acoustic amp and when I plug my soundhole pickup into channel one, while I have something hooked up to either the DI outs or the LINE OUTs, it buzzes like crazy. If I plug in to channel one without anything plugged in to the DI's or LINE OUTS, or if I plug the pickup into channel two, it sounds fine. But channel one is supposed to be for pickups. If I plug a mic into channel one it doesn't buzz. Just with the pickup, when the DI's or LINE OUTs are plugged into something. Any idea what the problem is?
