OK so right now i hav an electric guitar, but i also want to get an acoustic guitar. I need to know what are sum of the advantages of getting an acoustic guitar, and what type of songs can i play on it that i cant on my electric. Also!, what is the average price for a good, acoustic guitar.

I would say the biggest advantage of an acoustic is that you dont have to take an amp with you if u wanna play.

Pretty much anything that can be played on electric can be played on acoustic and vice versa.

The defining characteristic between a bad acoustic and a potentially good one would be whether or not it has a solid top. These start at about $200 (USD) I believe, so anything from there up. Of course theres gonna be exceptions tho.
