Here's the thing, I do take an extra bass to gigs (or at least I did) one fretted and one fretless, as I needed both. In addition, I have a DI on pedal board, so in a way, I have a back up amp too. However, going forward, if I ever get to gig again with my '2 bass band', I'm going to try just taking the fretless and alter my playing style where appropriate.
