Durability
A pickguard protects the face of your guitar from pick scratches. Even experienced guitar players can scratch the finish of their guitars if they play a little too enthusiastically. Young guitarists are especially prone to rogue pick scratches. A pickguard can extend the life of a guitar but isn’t necessary for players who only fingerpick or rarely use a pick.
A straight headstock doesn’t exert as much tension on the strings as a tilted one does. Guitars with straight headstocks are less expensive to make but may be more prone to warping over time. Most higher-end guitars have tilted headstocks that help balance the tension on the guitar’s neck, extending its life.
Tuning machines are key (pun intended) to the overall sound of your guitar, and they take a lot of wear and tear from daily use. They may become loose over time, particularly if they don’t feel snug to begin with. Choose a guitar with tuning machines that are snug so they won’t come loose but not so snug that they’re too hard to adjust evenly.
The gear ratio of a tuning machine tells you how many times you have to turn the key to wrap the string around the peg one time. A tuning machine with a higher gear ratio gives you more precise control over the guitar’s tuning.
Sound
Finally, the most important thing to consider is how the guitar sounds when you play it. This is essentially a matter of personal preference, and that’s how it should be. Hold the guitar in your hands, see how it feels, and listen to how it sounds when you play it. You don’t have to be an experienced guitar player to know when a guitar sounds right to you – you’ll hear it.
