Not really distorted . . . on some small guitars it feels like there just isn't any more to give though when you start to dig in with the pick. It's almost like smaller guitars kind of act like compressors - quiet, soft parts get the top humming and loud parts don't really get any louder. Bigger guitars take more energy to get the top humming but once they do they seem to have a little more dynamic range.
Of course this is in my experience in generalities (all different guitars play differently to a point).
