Are you torn between playing the acoustic or electric guitar? Both of them have their own pros and cons, but it really just depends on the sound you're looking for!
If you're more of a folk, country or bluegrass fan, you'd probably enjoy the acoustic guitar. Whereas if you're more drawn to metal, or hard rock, the electric guitar is where you'll find your fun! Choosing a guitar that closely represents the music you enjoy gives you an upper hand and you'll probably learn to play faster since you've got music to mimic while you practice.
The acoustic guitar is easy to grab and go and play wherever you are - home, the beach, the bus stop, anywhere! You don't need an amp or any electronic accessories. Keep in mind though, that acoustic guitars tend to be bulkier than electric guitars and can be slightly more difficult to learn.
Electric guitars are great because they offer a great deal of sound diversity with distortion and effects. You can create aggressive sounds that acoustic guitars aren't capable of. Electric guitars are thinner than acoustic guitars and are easy to carry, but if you want to take advantage of all of the sound capabilities you'll need electricity and an amp with you.
If you still aren't sure what you'd like to play, take matters into your own hands and go to your local music store and play both for a while. Maybe you'll find that you naturally gravitate to one over the other. Who knows, maybe you'll be rocking house like The Beer Brothers Band someday!
