Sorry, VH2...whatever that is?

Also, I have auditioned both the TC Helicon and Digitech units for guitar. Both were o.k...good for their intended use.

Thing is, my Tyros system(whatever it's called..or whomever makes it)seems to me to sound just as good as the TC Helicon and Digitech systems I auditioned.

For me anyway, vocal harmonizers don't replace the real thing. It's one thing to see one person on stage and hear harmony coming from one person. It's a totally different thing to have three folks on stage where you can hear the differences in their voices, see their expressions...hear the natural sound of harmony that way.

For me, vocal harmonizers just add interest to the song when I'm playing solo. Nice to have something a bit different at times rather than just the melody...sort of like changing keys in a song now and then.
