Just wanted to give a shout out to great customer service from D'addario. Bought a set of EXL 190 nickel rounds .040-.100 I really like these strings! I used them exclusively from about 1983, through the '90's. After playing many different brands since that time, I've come full circle. Anyway, I seemed to be having a problem with a chorus-y sounding E string. Tried restringing it, to make sure there was no twist. Also, I made sure I had the string height right. Was better, but still not quite right. I emailed Don Dawson at D'addario about my problem. New string is on it's way! Big thank you to D'addario for excellent customer service! Like I said earlier, I've come full circle, and I'll be sticking with D'addario from now on.
Used the XL's for years until switching to Flats, and Chromes just don't do it for me. D'addario's are good strings tho. Any string maker can let a few "bad strings" out to the public. Cool they sent one right out to you. sounds like it wasn't user error. (you checked for twist) just maybe a bad string.
My experience has been that is depends on the bass. comparing XL nickels with DR lo riders, the latter sounded better on '79 ray whereas the XL worked better on a 5 string celinder. I like the fact that they publish the tensions allowing us to buy tensions matched sets fom the site (a little extra$ tho) which makes a big differnce in playability.
I suppose that when you make as many strings in a day that D'addario does, there's bound to be a few bad ones here and there. If it was all the time, that would be one thing. In this case, I just chalk it up to things happen sometime. The string is usable. I've gigged, and rehearsed with it, and it's really not noticeable in those settings. I just don't want to take a chance in the studio with it. Otherwise, I'm back to realizing why I liked the XL nickels in the first place.
I switched to D'Addario Chromes a couple of years ago and I really like them. I'm using them on both of my basses and for the way I play and the sound I'm looking for, they're hard to beat. I used D R strings for years - and I like them too. I have a set of D R flat wounds sitting in my desk drawer but I haven't been motivated enough to take the Chromes off and put them on.
