No flash plug
Digitech Vocalist Live 3 is a self contained vocal harmony pedal which takes its pitching info from the input from a live guitar and generates harmonies from that.
You can plug your guitar and mic directly into this for a compact processing unit that according to Matt is blindingly simple to use.
