Product Review

Depending on your purpose, this may be great, or just an added texture. It's by no means a replacement for real gang vocals. And it's not a replacement for a good Harmony processor. When working with music that has a lot of sound, like Punk or Rock, it gets easily buried in the mix. For recording, it's really just a "thickener" that adds texture to a vocal. Perhaps it's more appropriate for live use, where you may not have the choices you have in a studio. That's probably why it only has a "mic" input on XLR, and no line level input. It has it's niche, but maybe that's enough.
