Product Description

Applying the brightness and clarity of our proprietary cobalt alloy to a flat wrap wire gives rise to an innovative new bass string that features the tonal qualities of a roundwound with the silky smooth feel of a flatwound string. Gauges: 50, 70, 85, 105.

From the manufacturer

Slinky Flatwound Bass Strings

Enhanced lows, focused mids, and crisp highs
Round wound sound
Less finger noise
Ernie Ball’s optimal core-to-wrap ratios ensure comfortable tension and playability.

Slinky Flatwound Bass Strings

Ernie Ball Slinky Flatwound Bass Strings bring together the smooth feel of traditional flats with the modern power of cobalt. Cobalt, a metal that Ernie Ball introduced to the electric string world, displays a very strong attraction to the magenets in guitar and bass pickups. This enhanced magnetic relationship results in a flatwound bass string with increased brightness, clarity, and output without the finger noise of a round wound string.


Ball End Our ball-ends are manufactured from high quality brass wire rod to our exacting specifications.	Wrap Wire Slinky Flatwound bass strings are precision wound with a patented iron-cobalt alloy wire providing higher output and clarity with superior intonation and consistency.	Core Wire The core is made from tin-plated high-carbon steel hex wire providing excellent durability.

Bright yet versatile. Consider going one gauge lighter than normal.

Reviewed in the United States on April 9, 2024

Color: Extra (40-95)Style: 4-StringVerified Purchase

These strings have the brightness of a roundwound and the feel of a flatwound. I play many genres, so a versatile string is important to me.

On my P bass, I can roll the tone all the way off and get some really articulate low mids in my tone. With a mute, they have an excellent Motown thump.

They are also fantastic for slap. I only need to turn the tone knob up to 40 or 50% with a fresh pack; they have plenty of room to mellow out and still maintain their clarity. With the tone wide open, you can absolutely shred some rock or metal tunes.

I initially purchased the hybrid set (45-105) and after 5 hours of practice in a day I noticed my fretting hand was getting sore. I bought one gauge lighter (40-95) and these have similar flexibility to the 45-105 set of roundwounds I'm used to.

The lighter gauge 40-95 set is much easier on the fretting hand. It has a brighter slap and pop tone, as well as a bit more clarity above the 12th fret. The hybrid set is warmer. Both sound really good, it's mostly just down to personal preference. Any tone difference can be dialed out with some EQ.

Compared to Thomastik Jazz flats . . .

Reviewed in the United States on March 29, 2024

Color: Super (45-100)Style: 4-StringVerified Purchase

. . . these are excellent strings IF you like throaty, meaty, articulate in a good way bass tones -- which is also what TIs provide. These are what I think of when I think bass guitar sound. I play solid, up-tempo, catchy, riff-based, melodic, pop/rock/surf/punk. I am NOT nor will I ever be a slapper.

These EB cobalt flats are soft to the touch but not too soft, residing in a Goldilocks zone for me. The TIs are a tad softer, maybe a tad smoother but honestly if you didn't have them side-by-side on identical basses, as I did, you might not be able to tell. Coming from a guitar player's perspective who never before played bass beyond casual noodling, who recently auditioned 14 different bass guitar brands, with mostly different strings on each, and who is 90% of the time using a pick (Dunlop Tortex .60 mm), I would be (and will be) happy to continue to use these as my mains on one of my basses. The TIs are on the other bass, and it was my first time using those too. There, instantly, I understood why most bassists regard TIs in such a high stature. They have a certain je ne sais quoi when playing them -- tone and feel. These EB cobalts are not worse, just different, but they ARE in the same category as the TIs, at $25 less. McLaren vs Ferrari. IDK, personally I think if you can swing it, it's worth it to have both. Knowing what I know now, why anyone would ever want to play the stock Fender rounds after playing these EBs or TIs is a complete and utter mystery to me. Yet that diversity is what makes life interesting.

New favorite flatwounds

Reviewed in the United States on April 9, 2024

Color: Super (45-100)Style: 4-StringVerified Purchase

I was very pleasantly surprised by these strings . Lower tension feel but not as low as Tomastik Infields which is a good thing for me . Strong fundamental tone . Slightly tacky feel but not enough to bother me . I had been using the flexible flats by La Bella and was pretty happy with them however these just have a fuller sound . Maybe it’s the cobalt ? With the cost of flats it can be expensive to shop around and try new strings. I’m glad I believe I’ve found my go to flats and they are reasonably priced . Other than that slight tackiness I’m 100% sold on the tension , sound and string life and it’s not so tacky that I don’t find myself sliding on them much more than on say a round wound set .

A bright flat? What's up with that?

Reviewed in the United States on April 6, 2024

Color: Extra (40-95)Style: 4-StringVerified Purchase

I bought a used bass that had flats on it. I totally loved the tone and went on a serious search to find out what strings they were. Turns out they were these only 1 gauge heavier. I love the E.B. slinky gauges in 40 - 90. Your string action can be a little high, but it's so easy to press down, it won't matter. The flats are smooth and growlie on a P bass. I'm sure the brightness will wear off in a few months and settle into its long term tone. If they're too bright for you when you first put them on, just crank down the tone a hair and all will be good. Even if you buy the heavier gauge strings, I'm sure they'll all sound great. Get a set and give 'em a try.

Great when new.

Reviewed in the United States on September 11, 2022

Color: Super (45-100)Style: 4-StringVerified Purchase

These are great strings when new. They sound great and feel great. However, they don't age well. Most of us flat wound players like our strings after they age a bit and get settled in to that sweet spot. Unfortunately, these strings get rusty, crusty and really rough feeling after a couple of months. The tone changes, they lose the warmth and bottom and develop an unpleasant high mid clank. I'll go back to Chromes. I can leave those on for a couple of years..

Best Flatwound Bass Strings of all time

Reviewed in the United States on December 13, 2023

Color: Hybrid (45-105)Style: 4-StringVerified Purchase

Ernie Ball Slinky Cobalt Flatwound strings are the best flatwound bass strings ever invented by mankind. Period. These strings are pricey compared to round wound stainless steel or round wound nickel bass strings, but they last 3 times longer and are totally worth the cost. I have EB Cobalt Flats on 4 of my 14 basses.... Sterling Stingray 5 HH, Sire Marcus Miller V5 (jazz bass) Fretless, Fender Player Precision and Fender Vintera 60's Jazz. These strings eliminate finger noise and sound similar to round wound strings with zing and mid-range growl. Not quite a piano-like tone like fresh rounds, but that kind of tone is not needed for classic bass tones. I was always disappointed with average flat wound strings. Thought they were dull sounding and lifeless. EB Cobalt flats are anything but dull and keep their tone even after months of playing. Highly recommended for bassists who want a long lasting string with a much better tone and range than typical flatwound strings on the market. A+++

Should have switched years ago

Reviewed in the United States on April 19, 2024

Color: Hybrid (45-105)Style: 4-StringVerified Purchase

Loving these flats! Always wanted to try flat wound strings but never did. Finally switched and will not go back. These when new are not that much darker than my well worn round wounds (usually EB super slinky or GHS boomers) but I expect them to mellow a bit. The round wrap reduces finger slide noise and is much easier on the fingertips.

When I want some more brightness or twang I just turn up the treble/tone knob on my Sterling Stingray Sub4.

I installed these strings and let them stretch for a couple of days before playing with the band. They held their tune through the night and had a great sound. The other thing that I like is they give a round-wound sound but since they're flatwound they don't rip my fingers up. Highly recommended.
