I've been playing for about 25 years and I can think of 10 basses that I've owned, but I feel like I'm forgetting something, so I would say in the neighborhood of a dozen.
I'm currently in the "#1 club" in that the number of basses I currently have is, well, one! Weirdly, I have more guitars than I do basses at the moment (3 guitars, one being an acoustic) and I barely play guitar.
