There are many different types of acoustic guitar reviews. And beyond that every one has a unique sound(s) to go with it. You can make guitars talk, make different sounds with it that doesn't even sound like a guitar. With different pedals you can play alone with an acoustic and record and loop as you want the: rhythm of drums, the harmony, the melody, a rhythm guitar in the back ground and then do a solo in the middle of all of that sounding like an electric guitar.
