I have my wav files on a VoiceLive 3 extreme. A bit pricy, but it covers all my harmonies, vocal effects, autotune etc and also guitar effects in one package. Just plug the Voicelive 3 Extreme straight into a PA and you have a very professional sounding setup. Of course, like all really powerful units, the Voicelive 3 Extreme has a learning curve. What I really like is that the Voicelive 3 Extreme allows me to set up all my guitar and vocal / harmony effects to automatically turn on and off at precise moments in each song. You just play and look at the audience or whatever... No jig dancing or foot stomping although it will let you do that if you wish.
