When I first heard about upright electric bass from my son, I knew it was a musical instrument. I was thinking that it looks something like a guitar. Well, I was right. It's a string instrument but it's a little different than the traditional and bass guitars that we all used to know. It is upright as the name says and it's a lot slimmer than an ordinary guitar. The electric bass is very light and has a sweet sound. The boys in school (including mine) are getting crazy over these guitars and every one is eager to have their own instrument. My son and I are both saving for it.
