Is it normal on a Torpedo Live that the output level parameter changes the tone? I think it should be the same just with different volume, but on my unit the closer the output level gets to mute it sounds more like a dry signal, and the closer it gets to 0db it sounds like a processed signal, even when the output level is on mute it still has a little dry signal on the line out/headphones out, the setup is wet/wet. could my torpedo live be defective?
