I'm not really sure if you could use this one, but if it were me, I'd go with one of the more expensive units that offer more functions therefore more control.
Either the TC Helicon voiceworks or the digitech makes a nice unit called, I think, the live 4 pro.

Part of the beauty of this thing, at least for me, is it's simplicity and lack of settings. It sounds good out of the box, no decisions to make. But of course it doesn't have all the functions of the bigger units.
