Shape does not affect the sound.
The shape is done for look and for ease of use, some playing styles need certain shape, to rest arms, or to support the instrument, or to balance it in the hands, or to be comfortable to play while seated.
Electric instruments rely on pick ups, strings, the mechanics to support strings, the body rigidity and quality to keep the instrument straight and to provide proper contact between strings and board.
Friend of mine is a professional maker, the biggest part of the price is how precise you want it to be. Shape is last concern for him.
