I almost exlusively play one bass, but currently own two. I am of the multiple basses mentality, just have more pressing budget items than new basses.

With so many ways to configure a bass that drastically affect the sound and feel, you could have a hundred of them, none redundant. Then you have to ask yourself, "do I really need two six-string, semi-hollow, fretless, active, spalted-maple-topped, extended-scale bass guitars, just because one has soapbars?"

I guess that's up to you and God to decide. The important thing is that we use our talents and whatever instrument(s) we're blessed with to bring honour to our Father, who every good gift comes from.
