Well, it's part synthisiser and comes with 6 pre loaded effects. I think one of them sounds at least a bit like a guitar. One of the cool things about it is you can hook it up to a computer and change the sound through there.
When I started playing guitar, I played until I got blisters, but trust me, after a while, you can play for hours without your fingers hurting. (unless you have to go out in the cold at 7:30 AM to play for an early church service. Something about the combined cold and time make for an unpleasent finger experience.)
