Quickly: Auto-tune mic modeling + + esser + comp + double EQ
Rack Model
jacks I / O and MIDI control and footswitch

UTILIZATION

Very easy to use, each module (EQ, comp everything) has a small corner him and buttons DDIS, all with a 2-line screen and a legible wheel.

SOUND QUALITY

No breath.
The presets are handy, as it explores a quick whole spectrum of possibilities of the device.
Auto-tune little use.

OVERALL OPINION

ATTENTION amimenter not in (I had not the power supply source and I tried with 500 mA: it's horrible, it seems to have a robot voice).

Otherwise, there's everything you need for voice: perfect for live.
