I have been doing some lyric translating for a Japanese metal band, and wasn't surprised to find out that the guy I was working with was the bass player. I'm a bass player too, and I used to take on all kinds of projects in the bands I was in. I think it's because I always felt like I had to be the one to get things done.
I find that similarity with lots of other bass players. Hard working, smart, maybe a little less confident than guitarists and singers. But at least we aren't drummers:)
