That's what I've been using it for... haven't had a problem with it. It's definitely sounding better than the coloration that comes from the tuner's bypass. I don't hear a difference when I plug it in... there might be one beyond my ability to discern it, though.
edited to note: this is an LDR pedal that I'm using... if you have a multi-output volume pedal other than that one, I don't have a clue (as is the case with so many things.)[This message was edited by Nicholas Dedring on 28 September 2004 at 10:09 AM.]
