That is an Ibanez. The Korean ones are the low end of their models. The headstock appears to be rosewood as well as the back of the guitar, but I would have to really look at it to tell. Low end guitar makers stain woods to look like other woods. They are OK guitars, great for somebody that doesn't want to drop too much cash starting out. These are made for Ibanez by a Korean company whose name escapes me right now. With a hard case in the $125-200 area retail, a dealer would give you about $50-75.
As an aside, Korean guitars are getting better and are no longer the bottom of the guitar maker barrel. They are about where Japan was 15 years ago. Many low end brands are out sourcing to the Phillipines and China. Epiphone, Jackson, Ibanez, and about twenty other companies are having guitars made in Korea.
PS - I noticed this, it appears to be an early nineties vintage. Also Ibanez is a Japanese company, case you do some research and get confused about where it is from.
