I've only been attempting to do vocals the last couple of years. I thought the Harmony Voice Live2 would help me. WRONG! My wife said you better not go out gigging with that unit, you sound awful. Yea, total honesty, better hearing it from her, than from the audience. I do have the Harmony M, I use it on a limited basis, works for me and no one's asked me to pack my gear up and leave the gig.
