It is very easy to get started using the Vx400. You just power it up with the included power adapter and plug in a microphone and a speaker output and you're set. If you want to use the included recording software it takes a little more time. Everything you need is included on the disc and once you get all of the software installed you can hook up the Vx400 to your computer via the included USB cable.
The effects the Vx400 has are amazing. My favorite effect to use on this pedal is the pitch change. With the expression pedal in the heel position, you can get a low, bassy, monsterous tone, and then change to an extremely high pitched wine, in the toe position.
I have had this pedal for about 2 years and it has done exactly what I bought it for, which was voice changing effects. As far as durablity goes this pedal is not anything to brag about. After a while something happened on the inside of mine and I think some springs popped loose or something. I haven't really needed to use it in a few months so I haven't tried to fix it or tried to see if I could get a warranty repair. All around it has been a great pedal though and I would defnitely recommend it to anyone who needs a voice effects pedal.
