I've taken two to a couple of "important" gigs, ones where I was playing with featured vocal artist friends and really wanted to ensure there were no issues, but not nearly as often as probably I should have.
Now that I've got a gig bag that carries two basses, I have no excuse (other than it weighs as much as I do fully loaded, heh), but will still only use it fairly sparingly.
Since I always practice up on the bass I'm getting ready to use for a gig, I feel like I'm good at identifying possible issues (and did so once with a dying toggle switch + emergency solder work) beforehand. Not always, and I know there's risk involved in not taking a backup, but that's one way to keep things interesting.
