D'Addario XL 220's used to be my go to strings for my jazz and I still believe they're a good middle of the road nickel string. But having said that I tried a set of GHS Boomers recently and while they sounded ok on the p bass, they sounded really good on the jazz. So much so that I think my next set will either be a set of roundcore Boomers or nickel Super Brights that everybody, well almost everybody, seems to really like.
