Buying a guitar can be quite confusing, especially when you do not know a lot about guitars. There are some differences between all the different makes, models, prices. Here, you will get some pointers on how to find the right guitar for you.
First off, find a guitar that fits comfortable across your body. For those of you who are young, a full sized guitar might be too big. What you want to do is put the guitar on your body as if you were going to play. You should not have to lean over the front of the guitar to reach the strings.
One of the most important pieces of buying a guitar is how much money you have, or for you children out there, how much money your parents "will spend" on a guitar. For a beginner, any guitar will not do, the better the guitar is the easier it will be to start. A basic run of the mill brand will do, like a Gibson, or a Harmony. For those who are more experienced, the price of the guitar usually reflects how good it is. Normally, the higher the price, the clearer the sound, the better the construction.
If you have any in depth questions about what exactly a certain brand of guitar has over another brand, please ask your local retailer. They will be more then happy to help find the perfect guitar for you and your playing needs.
