BOSSVe-5 - White

Does this unit just have presets, or can you make adjustments to customize the sounds?

I'd like to use this for auto-tune vocals in a live situation but one comment said it would not work well for this. Any comments on using live?

Hi-help! i'm a busker, solo singer with a mic and a speaker and that's it . does it work without a guitar-just a mic?

this price is not include power adapter and the clip of mic stand?
