Boom. Any time I can play bass, I will.

I play at church a fair deal and occasionally get called on to play lead guitar because for some reason there aren't any people in church who can play an electric guitar, but if there's not a huge gap at guitar and a logjam of bassists, I still pick bass every time. On that note, I have also played drums a few times at church.

I also play bass full time in my band.
