For those of you who travel regularly to gigs via airline, do you bring a backup bass? I'm on the fence... I have 5-6 shows lined up in CA this spring for which I'll use my favorite modded P with EMGs - the upside of which is I can easily bring a spare set of strings and electronics and do a complete repair in a hotel room with minimal tools, and get parts or even a whole new bass at a guitar center if things went very wrong. But if anything went wrong during a gig (which it never has, knock on Alder) I'd be stuck doing an emergency repair or begging for a spare from the opening band. What do you touring pros normally do?
