Fender super champ X2

Hi
I thought I had purchased a Fender Super Champ XD following the recommendation from Dave Barret. However, when I got it home it turned out that I had been given a Super champ X2. It looks exactly the same as the XD I saw on display at the Music shop. The X2 has a USB slot. However, is it technically the same as the SCXD and will it sound the same. I would like to know before I start using it in case I decide to return it.

Thanks
