Hi, if you already don’t know this website is about guitars. A guitar is a musical instrument with 6, 8, or 12 strings. 12 string guitars are for more experienced guitarists. Guitars are either acoustic or electric. An electric guitar plugs into an amplifier. An amplifier is basically a loud speaker. An acoustic guitar has either metal or nylon strings, and it doesn’t plug into an amplifier, it has a hole in the center of the guitar to make the guitar sound louder and hollower. A guitar is used in hard rock, metal, blues, soft rock, alternative, and Mexican music. I hope you enjoy this website.
