Choosing your first guitar can be tough.
You want a stable guitar that wont go out of tune very often and a good set-up. It can be really hard to judge playability when you are a beginner so it is best to ask a friend who knows how to play if you want to go with second hand or sticking to a major brands brand new guitar is also a viable option. You can ask the store to set it up for you.
Knowing the overall genre that you want to play is also important. If you want to play heavier stuff it might be best to go with a guitar that has humbucker pickups on it.
Lastly, having a good looking guitar will encourage you to pick it up and play more often.
