Gary and Donny,
I did a little section of "Peaceful" to demonstrate the sound from my Digitech. On the "ooh, ooh, ooh" section I purposely did 3 repeats. The first one was with no harmony. The other two are with harmony like the Eagles. I wanted to show that a decent harmonizer can indeed spice up your sound.https://app.box.com/s/efe0slq497z4vukj0k1ncbwfoa5adc0c
