I haven't tried it on the 3 or 3 Ext, but ever since the Voicelive 2, they have been offering audio output as a harmonizing option. I don't think you would have a problem. The Extreme is expensive, but it provides a looper, guitar effects, playback of audio files with automation of effects and recording via USB. The only negative I read was that it was a bit fragile. Again, mine is still in the box, so I can't comment on anything yet. Be careful you don't buy the fancy vocal/guitar cable (which i did) as it comes in the package. grin I waited and waited for the 4, but who knows when.... I'd be tempted to go along to a friendly shop and try it out or contact TC Helicon.
