determining a string guage

[CJ_Marsicano]

hi,

I have a fender 5-string custom jazz bass that I've had since 1996. I've _never_ changed the strings on it and they still sound good, but there is going to come a time when they'll need to be changed. How does one determine exactly what gauge strings is on a bass?

Get some calipers and measure the strings.
