I use this pedal in my band which I sing backing vocals for. The "group" setting on it does add a good full sound to my vocal lines. Three of the other backing vocalists use it too and it does sound like around 8 people singing, however if you have the "wet" up past 60%, the latency can sometimes affect the timing. Other features on it like tha octave down and octave up are great too, however like the other settings once you pass a certain amount of "wet" your voice can become a bit delayed and sometimes even out of tune. However, it really has added to our sound. If you are a main vocalist and you want to have constant effects on your vocals, Id suggest paying a bit more for a better vocal pedal. For the price, it's good! But I only use it for slight effects rather than an up front explicit effect like bands such as The Knife or other techno bands. In conclusion, it's versatile and reliable, but can defect your vocal lines if you have the effect too strong.
