I got the new bass home, tuned up, and plugged into the amp. It sounds good! It's fun to see at what frequency different things around the house resonate.
It's going to take me a while to get used to it. It is a five string rather than a four like my first one. Not only does the additional string make a difference, the spacing is a little smaller between them.
But ooooh, that new low B string does shake stuff.
