First impression when unpacking the unit: strength of the product. The hull is made entirely of metal, as well as push buttons and 3 different keys are nice and appear solid. The unit comes with an AC adapter, a quick start manual rather damn good and a USB cord to connect to a PC (you must also download a free program to manage the device on computer). Once the camera is connected and the power management phantom snapped up (two clicks to choose condenser microphone, which turns phantom power), we enter the heart of the matter: the effects! Overall these are quality, management is quite simple and really good presets. The availability of various effects makes the device even more relevant! It does not exempt to sing in tune, but it greatly improves what happens in the sequencer! It takes the camera in hand rather quickly and after a week it is part of set'up as one of the key elements! Perfect for a home studio, it can be easily carried and used live ... A great machine! (Attention, I live with not talking about the mixer and sondier behind because obviously it will not appreciate receiving a lot of reverb signal!) The downside, however, there is no management on / off, I made up for this lack by using the power strip when the device is connected, but honestly it's not practical.
