Hi, I've been researching different blender options and I'm kind of stuck on one feature. The XBlender gets great reviews, so I'm leaning towards that. But my concern is the actual blend knob. Will this decrease my clean volume when I blend in the wet? What I think I want is my clean signal to stay at a constant level while adding in some effects in parallel, giving the effects more of a "background" position. Can I do this with the XBlender or do I need a blender with separate volumes for each channel?
