I have the TC Helicon Harmony G that I have used in the past. I just got the Voicelive 2 today. The Harmony G has been replaced with the Harmony G-XT. The major differences from what I understand are that the new pedal allows updating of firmware and has improved voice detection. I have been very pleased with the products from TC Helicon. If you are just wanting some simple back up vocals you can achieve pretty good results if you play around with the settings and make sure you are not getting alot of bleed into your mic from other instruments to throw the harmonizer off.

In regard to the Bass, I was jamming with some friends and we decided to let the Bass player hook it up and do vocal harmonies with it behind my vocal. It worked great. It actually locks in a little better I think with bass since their is only one note to analyze.

I would go to their Facebook page or their web page and post a question about bass if you want info from the professionals .

Digitech has a similiar device which is good but I do not think competes with TC Helicon. I have also been allowed to play with the Roland VE-20 which has good vocal effects but I am not impresses with their current voice harmonization on this box.

Hope this helps.
