Such a brilliant piece of equipment, I have no words. It seems as though the days of blunt, lifeless live vocal sound are gone. This thing is an all in one package, the possibilities of working with it are imense, and it can be used in really a lot of scenarios, but the Extreme version of the voicelive 3 comes with a great priviledge of making it easy along with making it sound great.
First of all the tone function is so great; the compression, de-essing, eq, and other things that they won't even reveal what they put in this thing, it ''produces'' your vocals in a way that for me was never attainable live. And it kills feedback really effectively, but you'll have to learn how to setup this thing as it's a really complex system, it works great out of the box though, so don't fear. ;) I'm just saying that you can really get even a lot more out of it if you spend time studying it, as for me, I have it for a couple of months, and I'm still finding out new stuff that constantly amazes me.
I completely love the backing track & effects automation possibility, I've actually setup a preset for every song, with the song name in the title, I've assigned one button (in the button mapping section) to ''Play track'' and after that I don't have to worry about anything, the mixing levels, adding of harmonies, megaphone effects, doubles, delays, anything, after I programmed it, it just turns on on it's own, and I'm left in peace to completely devote myself to the performance. This thing actually feels so seamless to integrate into the band, and gives you great artistic freedom, while not affecting or burdening your performance. And the quality and what it adds to your sound live is unprecedented! :)
The best ''music gadgets'' I ever bought!! :D
P.S. I don't even need to speak about how good and correct it makes the harmonies, but be sure to tinker with it, and learn how it works, as you can really get brilliant results with some ''playing with the buttons'' ;)
