I was discussing strings with my luthier and he suggested a half roundwound string. I decided to give these a try. I have really enjoyed their sound. They have a very warm sound, but nice crystal highs when you need them. I use them on a '75 Fender American Deluxe Jazz and really like what they have done to the bass. There is one caveat though. They take a little getting used to. I have played full roundwound, and flat or tapewound strings. These have a very unusual texture when you first start playing them. They almost feel sticky. This is the only reason they didn't get 5's across the board. However the stickyness either goes away or I have gotten used them. No matter, I have chosen them as my string of choice on this bass. Great job D'Addario.

Once upon a time, I was sold on a very popular British-made round wound string. Then a guitar/bass tech I knew at the time told me that for all their merits, round-wounds (no matter who makes them) can be murder on frets. He then recommended the D'Addario Half-Rounds to me. That was well over 25 years ago, and I still use 'em on my '66 J-Bass. I just got a Lakland (with their own round-wounds, and while they're nice)I plan to change to the D'Addario's ASAP. They feel much smoother on your fingertips; are much more "fret friendly" to your bass; and can give you a warmer sound when you want it, as well as most of the bright punch of a true round wound.
