Has D’Addario always used the color coded ball ends? I replaced the strings on my tele bass with a set of Chromes, because I thought that’s what was on it already, however I notice the ball ends on the old set are all brass. The new set has multicolored ball ends. I put the old set on in 2015, and in truth at the time I wasn’t picky about what strings I used and this set was the only flats in the music store that day, so I can’t be positive that they were chromes...but I’m pretty sure.
