Mike,

I use the Digitech Vocalist 4 and I am very pleased with many of the set harmonies but you can also fine tune 50 the way you want them. I use many of the presets on gigs once or twice a week. On my site right now I have an example on Who's Gonna Fill My Shoes. It is a preset one part female harmony on the chorus. I am truly satisfied as it makes my vocals really jump out at you when I step on that harmony switch.

Later,
