BTW, after thinking about it, if I make a change in tone on my rig, I don't know that I want the soundman to be making changes to it. Of course, he has to do what needs to be done to save me from myself, but if I think a part of a song needs a tonal change, I don't necessarily want the soundman correcting it. But again, you have to do your best to match levels and get something that's not totally out of left field, and it's a good idea to warn them that you'll be stomping on pedals and you might occasionally need a tweak.
