It's a Sabine NEX-5200

I don't know a whole lot about it and to my recollection I don't think I've ever used it. I've found one review online saying it was pretty solid and good for adding a little oomph to leads. All I remember is that when I was a sophomore in High School I paid my buddy $20 for it and then never used it. So I was wondering if you guys knew anything about it. Thanks, guys!
