I use D'Addario Nickel 0.45-1.05 on all basses I have, an Extra long scale set for my Gibson RD Artist. I just recently found the still unopened set of the first bass strings I ever bought. I bought the wrong set (0.55-1.10, XL-230), that set must be old already, I bought them in 1996, but it was over 15 years old then already. The sticker on the back is funny, it reads: "Designed to fit Fender Jazz, Fender Telecaster, Fender Precision, Rickenbacker, Gibson Ripper, Gibson Grabber, Gibson G-3, Music Man, Ibanez Musician, Ibanez Roadstar, Ibanez FB, Ibanez Precision, Carl Thompson and other long scale basses". Sounds like late 70's/early 80's...
