It was pretty much Fender bass and Fender flats (or LaBella) or Rotosound rounds.
The "Flats" guys would hate it when they broke a string...they would have to take the new string outside and roll it around in the dirt so it would match the old ones!
I was a Fender P and Rotosound rounds guy myself.
If they were getting a bit dull (The Rotosounds) take them off and boil them for 10 minutes. It was amazing how much crud came out of them and how much better they sounded.
If you broke a string (over the bridge) then there was always the possibility that you could unwind back to the core, reform it round the ball end and wind the outer back round, especially if you had not trimmed them back when you fitted them. It never looked quite as neat as when they were straight out of the packet but got me by a few times. If you did carry spare strings they were usually the old set that you had taken off and they sounded like mud.
That was in the late 60s and 70s when I had one bass and no spare cash. I now have 8 and lots of spare sets of strings.
