This is an Alvarez mandolin. It is the "f-style" body. It sounds AMAZING, and is a great bluegrass instrument. I hate to part with it, but I need the money. I am including a Pro-Tec case with this instrument. It is in excellent shape, and sounds great. If you know anything about mandolins, then you know this is a GREAT deal. I may consider a trade for a guitar and cash.
