Backup bass has to be the same type imo - I use a US Precision and my backups are another US Precision if I`m doing a really important gig or tour, and a Squier VM 70s Precision for regular gigs. Both strung with Rotosound steel roundwounds. Sure due to differences in pickups and possibly bodywood there may be a slight difference in sound, but I`ve got to be as near as my regular bass as possible.

Pretty much exactly this.
I take two Precisions, both fitted with the same pickups and hardware.
If my main bass fails then I want to backup to sound as close to it as possible. Not for consistency or to make sure the band sounds the sane for the rest of the gig, just because I like the sound and I want it to be the same.
