G.P. – Many young artists start with the acoustic guitar. It is easier to study and also is cheaper to buy, especially for those who are just starting or those who do not really want to build a career around it.
But if you want to be part of a rock band, then you would really need an electric guitar. It’s safe to say that you can get them for cheap online, even with shipping. You can visit sites like GuitarCenter.com.
Also, if you are interested in an electric viola – guitarcenter.com, they also have it there.
