XL Chromes Flatwound Bass Strings ECB80, 40-95, Super Light | XL Chromes flatwound bass strings deliver smooth feel, warm tone, reduced finger noise and exceptional durability.

I have a through-body Mustang bass. Since I bought it, I always used LaBella Mustang Flats because of the perfect fit... I'm surprised more strings don't market specifically "for Mustang". But these strings, in the medium-scale set, are PERFECT for a through-body Mustang.Also, the sound is excellent. The E string has (at least on a brand-new set) just about the liveliest sound I've ever heard on an E string. Ya know how sometimes playing a note on the A string vs the E strings, even on a brand-new set, sounds way, way different in tonal quality? That problem is really minimized with these strings -- again, at least on a brand-new set. I'll be keeping any eye out for how the E string deadens with time, but as I get a better ear with time, I find that I need to replace my strings about every 3 months anyway, otherwise everything starts sounding dead to me. Too bad Thomastik-Infeld doesn't make their Jazz Flats in a scale for through-body Mustangs, those suckers sound good forever! (hint hint, T.I.!)Anyway, these strings seem to have noticeably better sound than the LaBellas, especially on the E. I really like the gauge too, they just feel right. May have to become a lifelong d'Addario fan!ADDENDUM AFTER GOING THROUGH SEVERAL SETS: Still loving them! I usually get 3 to 4 months on a set, and then the dullness starts to kick in too much. Although even after 4 months, you might really like the sound, they still sound good, they still play well, and they still stay in tune -- they just don't have that lively bright quality like a newer set. They also age very, very nicely, in that each string ages equally, even the E string, which is really surprising since I've found that the E string (with other brands) tends to go duller faster than other strings, and gets to be way-too-dead very quickly. Not these babies!!! The E string, even after four months, sounds comparable in tonal quality to the other strings and still has good sustain... again, just losing that brightness to age at the same rate as the other strings.UPDATE: after many, many sets of these strings, they are still my favorite for a Mustang Bass instrument with through-body strings. They sound good for a long time, getting "deader" very gracefully, including even-balanced aging and tone on the low E. They sound so good aged, that it shocks me when I throw on a new set and hear how bright they are!! I'm like, whoa, sure, they weren't bright after all that time, but man they still sounded sweet!

Been playing for a long time and I am in a band playing 60's through 80's music again. The roundwound strings I had been using just didn't seem to cut it for music from this period. Upper register notes just didn't have the authority necessary (strong mids) so I decided to go back to flatwounds. Did a lot of internet research and learned that the flatwound that appeared to me to be most respected by other bassists is the D'Addario XL Chromes. I'm here to say, these are the real deal and I think, through my bass's active tone controls, they have all the highs and lows I'll ever need for any kind of music. On one flatwound set I tried before (I won't mention the name), and on some roundwound sets, the B string was too hot compared to the other strings but with this set the string-to-string balance is excellent and, most importantly, my upper register notes have plenty of mid to cut through the mix and still sound like they came from a bass.Pictured is my lovely Pedulla Rapture RBJ2-5 with a set of D'Addario XL Chromes ECB81-5, the lightest gauge set of Chromes. And for you fellow Rapture owners, the B string was a tiny bit tight but fit in the bridge without modification. I was a bit worried at first because I like keeping this bass in original condition. I have a very light piece of foam at the bridge to eliminate unwanted harmonics and add a little Jamerson thump, and yes, these strings do harmonics well. Some flatwound sets do not. I am very happy with this set of strings.Oh, I need to add that my band plays tuned down one-half step. These strings handle that tuning exceptionally well at extremely low string height. The strings are a bit more taught than the roundwounds I previously had on this bass but not so much I cannot bend them easily. After setup (neck adjustment, string height and intonation) there is almost zero fret noise. I like that. These are great strings!

These are great strings that work and sound just as expected.

I have a Fender Mod Shop P bass which is my primary bass and 99% of the time I play that bass with a pick. (Insert pick vs finger style comments here:) At any rate nearly every round wound set I’ve tried was too harsh and tinny with a pick particularly in the higher end of the fret board. Regardless of how I EQed it, or iif I used different pick gauges it just didn’t sound right to me. BTW the sound I was chasing ranged from McCartney to the Police, from U2 to John Mayer.I put these XL chromes on and instantly they “sounded right “ to me, with a pick played between the pickup and the bridge. In fact I find I can really modulate the tone depending on the gauge of pick. They have great punch and growl, are pretty bright for flats and the tension is fairly light. Like everyone else I love the smooth feel of the flats, the lack of string noise and reduced concern about fret wear.If you’re a bass player who uses s pick like me you’ll probably love these strings! Cheers.

Why did you pick this product vs others?:For you bass guitar players that want deep rich bass and a comfortable feel without all the scratchy finger noise, these are the strings to get! They are solid performers that play well and stay in tune. Well worth the money. Before you order make sure you know the scale of your guitar because these strings come in different sizes.
