This pedal is something spectacular. What you can get from this little box at this price range it like it's free. I got it as a present for a band mate, he absolutely fell in love with it instantaneously. The results you can get from this little thing are unbelievable.
The vocals can easily sound like a professionally produced vocals and the crazy thing is that you do it on the fly and can do it LIVE. The vocalist will do it on the fly not the sound guy operating the front of house. You won't be relying on anyone else to make you sound amazing.
This pedal is very versatile, you will achieve amazing results both live and in the studio.
Live, you will be able to make you're choruses sound massive with the thick option or even the group option. Or your verses nice and cute with the octave up mode. You're live sound will start to stand out of all the other bands (if it already does stand out, you will be even a step further away from the competition :)).
In the studio this pedal also performs like a beast. If you split your signal before you hit the pedal you could save a long time by recording a dry clean vocal track and a full produced vocal track at the same time.
Could go all day long about how cool this pedal is. It's built like a tank and if you are a guitarist or bassist that use pedals, you won't struggle to incorporate this bad boy in your pedal board next to your other beauties.
