Some peeps here play and record in several projects, and while some say everything can be done with a 4-string P Bass and flats (and tort, of course), others prefer tools targeted for specific results.
When I practice at home alone, one bass will do. When I gig, two minimum — especially if there are mixed tunings required. When I record, I bring three, four or more; I make sure I have something on hand the producer and engineer can work with. And it’s nice to have backups when one or two basses are out for set-ups or repairs. But like I said, If I’m just playing alone at home, none of this matters; one is enough.
