Back when I was playing a lot, I streamlined my bass and string stuff. I had multiple MIM J basses all loaded with different pickups and control setups for the different stuff I was doing. I also used D'Addario round wound nickel all in the same gauge on all my J basses because it was the most common strings I saw when I would be out of town or out of state and visited local music stores. I had one exception, it was still an MIM J but I bought it from a kid who had the nut cut for much heavier strings than I was using on my other basses and it sounded good so I stuck with the gauge and brand he had on the bass when I got it, which I would buy mail order three sets at a time which would last around a year as it mostly stayed at home. I realize this flies in the face of conventional wisdom regards criteria for string selection, but it served two purposes that I found very helpful; with the exception of the one bass with heavier strings, all my basses played the same no matter what they sounded like, and I could go into most any mom and pop music store anywhere and buy strings that i was used to if I got caught out without spare strings.
