You can tell, this guitar has a very bright sound, this one has a dry sound, and this one highlights the serious impressively. I'm sure you understand everything you explain, and then you ask, "So why choose that?. After all the explanation I gave you, will you know which one you sound like?, Of course no. You must have a good time for someone learn to distinguish the sound quality of each guitar. Then you find out what the sound that pleases you most. You can also say, I want a guitar that has the sound of Slash, for example. There are people that break the head for it, but beware, often the sound of the guitar you hear is due to the effects and you can use to simulate these effects. So if not break your head over the issue of the sound of the guitar now.
Most likely is you have a guitar to learn to play and finish with a different one, when you've learned to discriminate one sound from another and you are sure the sound you like best. Remember that the vast majority of players had more than a guitar over his career, so do not worry too much at first by the particular sound of each or by the advanced features they have. Instead worry for feeling comfortable with it, that you really like its shape and color and you can brag to everyone. Remember that having a guitar you love is actually bigger than stimulation can have to start turn to play.
