How many of you have a backup bass? I'm enjoying my carved Juzek/Czech/? bass, but am aware that it will eventually need to have seam/crack repairs due to the nature of the beast. If you have a backup, to what level of quality do you get? I would assume that the backup would not be carved, but not a bottom of the line ply. My primary playing is orchestral for now, but I wouldn't mind something a little more versatile in a backup.
