The band has been working on a number of songs that require a drop D tuning, and a few others that have some low Bs. So I was forced to take advantage of an opportunity posed to me by my stepson—a six-string bass that he needed to move. He got me a very good price for it.
Turns out, it's the same line as my four-string bass.
I'm trying to get used to the new fingerings, and so far, I like. My daughter (a celloist and fledgling bass player) is also pretty happy to have a new toy around.
