Well you have a Dean Playmate...that's your first problem.

Just kidding...not really, it sounds like your intonation is off maybe. Plus since you have (no offense) a lower model bass it could probably use a professional tune up, truss rod adjustment and all that good stuff.

Take it to a luthier or your local guitar shop, they'll tell you what's wrong, or charge you far out the ass and do nothing.
