Usually only one, sometimes 2, but never as a backup, if i bring 2 its to fit the songs or cause i feel fancy!
All my basses are passive and checked on a regular basis and i never broke a string.
I know, **** always happens when you last expect it but i feel the risk is pretty low!
The only thing i ever had was a flat battery when i used an active bass years ago.
Mind you i drive without a spare wheel to so who am i to talk...
Yeah, I've had to replace a blown out tire, too.
I guess it's just because if there's one thing I'm NOT known for, it's luck. Lots of things in life seem to rearrange themselves to mess me up.
Lots of talk about breaking strings on here, but honestly that's not even what I'm worried about.
