Best on the market
Digitech has long been ahead with vocal effects units (they also killed the opposition with guitar effects until they discontinued the GNX4, but that's another story).
The Digitech Vocalist Live Harmony has all the effects a vocalist would normally want without going overboard into obscure stuff (like reverse delay etc.). It excels in 2 areas: the effects are GOOD like, you don't hear any better until you get to the high-end studio stuff. The other thing is the tweakability. They have nailed it with this feature. Instead of an immense amount of off-the-wall effects there are an immense amount of parameters for each and that's what vocals are all about. A small tweak can make a big difference.
For more mainstream stuff the backing voices are fantastic. For modern stuff voices can be significantly de-humanised with good pitch-stepping and distortion. Can't go past it!
