The bass guitar is a great instrument to start off on if you are wanting to be in a band. I say this because I have personally known a few different bass players playing in bands who have very little experience. I know that it takes a lot to be a great bass player, but it takes very little to get started. In saying this, it’s also pretty easy to find a cheap bass guitar instrument online these days. I you are patient and know where to look you can find plenty of basses under $100. I never would have been able to do that years ago.
