My favorite flats by a mile
For me, Chromes are the best flatwounds out there. And I’ve been through them all many, many times. Chromes have the smoothest surface with zero friction, and set up very low without ever having any buzz. They play very fast and work well on P or J. The quality control is extremely consistent and once broken in they sound absolutely amazing. Be sure to give them about a month before you judge them. Soon they become extremely thumpy and warm. I like LaBella too, but have stopped supporting that company because of so many bad D and G strings. The company does not acknowledge a problem yet it’s reported heavily throughout Internet forums for over ten years. The issue is that the strings will buzz no matter the action height.

Really liking these. Great E string tonal quality.
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!

Really nice strings that add new options to my sound
Been playing bass in a cover band that plays a wide range of mostly danceable music: Pop, Top40, R&B, Funk, anything groovy. I play two Fender Jazz Basses. One is a standard MIM and the other is a Japanese Aerodyne with P/J pickups. I have been playing Rotosound Swing Bass Roundwounds on both. But.... I have been noticing that with this kind of music I was always turning down the tone and bridge pickups to get a deeper sound like on most of these original tunes. Also found myself playing the Aerodyne almost all the time because of the P Bass pickup and it's tone. Went online and researched various options for getting that genuine tone from the 60's and 70's and learned that Flat Wounds are where it's at. Caught some great videos on YouTube about these strings and decided to give them a try. I'm glad I did! They are a huge step in the direction I was trying to go. Put them on the Aerodyne, gonna keep that one as my groovy axe and the MIM Jazz will keep the roundwounds for when I need to rock out and want that great lively tone they produce. The flatwounds feel smooth slick and amazing to play. They are a bit stiffer with more thud than rounds and also have less ring. Which is good for certain kinds of music. I noticed with them I don't have to mute open strings as much and they naturally produce more of a deeper thumpier sound. They have great sustain, so they're not deader, just have less of the higher overtones of rounds. I also noticed that my tone knob is way more responsive with these strings than with rounds. Using the tone knob and blending in the bridge single coil pickup give me a much wider range of tones now than I ever had before. Go figure. I can also crank up the tone and the bridge pickup and get very close to a roundwound sound for certain tunes and not have to change basses. Overall, I am very pleased with these strings and the way they have added more options to my sound. I would recommend them to anyone looking to broaden their pallet of sound or discover for themselves the deep soulful funky tones these strings produce and why they are such a big part of some of the greatest music ever recorded. MORE BASS!!

Best Bass Strings - Hands Down!!
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.

Fantastic bass strings. Usual D'Addario quality and a great tone. They have a bit more warmth than round wound - I love the sound and the smooth feel. They seem much easier on my fingers. They still have a degree of brightness to get a bit of 'growl' into your playing. Highly recommended - all of my basses now have these or the tapewound equivalent.

tout est dans le titre ! des cordes de qualité superbe pour un jeu extraordinaire, juste dommage je ne trouve pas un jeu de diamètre plus gros, la taille au-dessus et c'était la perfection

Ottime corde per i miei gusti, suonano bene e scorrono anche meglio. Top

As cordas lisas são demais. Gostosas de tocar e muito bacanas para quem procura um som mais aveludado ou grave. Mas nada justifica a pequena fortuna que estão custando, estes tipos de cordas. Comprei em um preço promocional, o que me custou uma corda nova, mas já com dois pontos de oxidação. Esta não é a primeira vez que isso acontece comigo. Como são cordas caras e que têm pouca saída, vale a pena escolher bem o fornecedor.
