I am really amazed at how good it sounds and the effects that it produces. I wanted something for boosting vocal parts. This will definitely do the job. Ruggedly built too.

This pedal helps fill out my vocals, makes it fuller sounding. In fact, when I rap it sounds just like someone else is rapping with me. So cool:)

The effect can be very subtle or way overdone.. Be sure to judge min context. It may be hard to judge while you yourself are singing, so have someone you trust help you set it.
This pedal is the furthest thing from advertised. It sounds HORRIBLE and nothing like a "crowd" or chanting crowd. Don't waste your time or money.
This won’t replace a good harmony pedal. The gang/choir effects are ok but I don’t think I’ll use them a great deal. However £67 for a microphone Preamp with reverbs and that TC tone button is great value. Even having this in the chain improves vocals massively. It can also run on AA batteries. I didn’t buy this pedal for the effects simply for the reverb and tone at a really good price.
As a relative newcomer to solo vocal projects i found the Critical Mass Vocal Pedal to be extremely easy to use with a highly effective end product. The Pedal allows me to perform without the need to carry any bulky mixing equipment, so armed with just a small amp, a mic and the Critical Mass Pedal I'm good to go to perform in almost any situation.
Excellent product, very worth it! Greatly improves the voice of the singer.
MOST PEDALS ARE FOR VOCLS OF INSTRUMENTALISTS - THIS WAS ONLY ONE i SAW TO GIVE A THICKER SOUND BUT ITS NOT HARMONY - HARD TO DESCRIBE - THE REVERB IS VERY CONTROLLABLE THE CROWD EFFECT NEEDS TO BE UNDERSTOOD YET AND I INEED TO HEAR WITH BIG PA
