You have 3 basic choices of sound when you buy a guitar:
Nylon String Classical
Steel String Acoustic
A lot of people believe that the best choice is to start on an Acoustic Guitar and build up to an Electric Guitar. However, I think that your first guitar should be appropriate to the style of music you enjoy listening to.
If you like AC/DC, Green Day, or say the Foo Fighters, you really need an Electric Guitar to get the sound you want. If you like Jack Johnson, Ben Harper or Taylor Swift, an Acoustic Guitar could be a good choice. Nylon String Guitars sound great for flamenco music, classical music and a lot of traditional music.
If you’re not sure what type of guitar is best for you, then just think of the music that you like to listen to the most. Feel free to contact me and I will give you a personalized recommendation.
