Maiden69 is right, a basswood guitar is slightly better than a guitar made out of cheese. As a first guitar choice you need to make the decision between the major three types of guitar,
a- no vibrato - eg a telecaster with no way to wobble the strings, or a wrap around bridge (for me purgatory)
b- parallel neck, therefore low string hight, wang bar vibrato, eg stratocaster
c- tune o matic with angled neck, great vibrato, eg Gibson style.
Then look in second hand shops, when you see one you like, look down the neck like you are sighting down the barrel of a gun. If the neck is badly, or twisted, bent you will easily see it, don't buy it. If the neck is straight and you like the feel and look of the guitar, buy it regardless of what it sounds like. If it sounds good don't do a thing, if it sounds crap, buy a good bridge pick up and swap it out. It will now sound fantastic if you made the right pup choice. Don't swap the neck pup it will always sound good. Happy new guitar day Rock and Roll.
