Fat strat has nothing to do with size what so ever. all it means is that is has a humbucker. And I think if your serious about learning and you know for sure your not gonna get bored with the guitar, Spend the extra cash and get the Fender Standard Strat. Good starter and very easy to upgrade parts, Pickups, Tuners, etc.
I am Comfortably Numb... :D
Oh yeah...STICK IT TO THE MAN!
