For clarification, do you have a bass that you use for basically every gig, or not? Personally, I do, I only have 1 bass, but I play Punk, so...go figure, right? If you don't (or do), why?
My go-to girl is Jenny, a hot rodded Harley Benton PB Shorty, but she is by no means my "one and only". I have a dozen basses at my disposal, and rotate through the lot. One or two weeks playing with Jenny, then one of the other ladies, then Jenny again...
Jenny, Jenny, Jenny, won't you come along with me
Jenny, Jenny, wooo! Jenny, Jenny
Jenny, Jenny, Jenny, won't you come along with me
Jenny, Jenny, wooo! Jenny, Jenny
You know that I love you, we could live so happily
Jenny, Jenny, wooo! Jenny, Jenny
