Yeah, I know the company claims it doesn't change the voice. Sure, whatever. I am not an expert, so I will not argue the point.
Here is another thought, *and a great test for it to show off just how wonderful it is at correcting a singers pitch*. Use it on a George Jones song... I assume it would work, but...
In all fairness electric guitars are often ran through numerous "magic" boxes, so if another box can improve a less than "perfect" voice of a less than talented singer, then I suppose it's all good.
I just think it's annoying then for "everyone" to kiss that singer's a** about how dang good they can sing. Especially when they are supposedly getting paid millions of dollars (which I don't believe, but that's yet another opinion).
Just a final point, I often like the "less than perfect" voices of some singers.
