For years, since it was a new line of strings in the early '90's, until GHS quit making them during the Pandemic, I used Progressives custom ordered in singles 45-60-80-105 or 106 on my Rickenbacker 4002 (yes, "2," not "3" or "1"). At present, on my Ibby basses, I use the D'A XL170BT set, 45-60-80-107, plus a 130 for a B string tuned up to C. I have a set of Optima RB's on another bass, which feel relatively balanced in tension to me. Occasionally I still experiment with other strings, either sets or singles, to keep up to date on what's out there.What gauges do you like?
