Ernie BallBass 5 Slinky Cobalt Electric Bass Strings - 45-130 Gauge

Firstly let me address the the 1 star reviewers most common complaint, which is that the strings unravel when you cut them. This can happen on any bass string as most of us will know. To prevent it you need to bend the string through 90 degrees with a pair of pliers about 15mm or 1/2inch behind where you want to make the cut and then make the cut. Don't cut the string before bending it.The string tone is not as bright as stainless and has a fuller sound and on my P bass there is slightly more "grind". Sustain is the same as stainless Ernie Balls as far as I can tell. I really like it for heavier rock and even pop and jazz. Not as suitable for blues, country and so on. But then flats or tapewounds are required anyway. It's horses for courses.From a pickup output point of view I do think they are louder when I'm playing through an amp, but when I'm recording I am not changing my gain at all so... idk.Anyway, bottom line, I'm using these strings now and have no intention of changing any time soon.

Ernie Ball are always coming up with new and inventive ideas.Cobalts are just amazing I placed these strings on my guitar around 6 months ago and haven't yet had to change them (I am in a hard rock band and these get a fair deal of punishment).the way the strings are made mean they do not rust and they stay in tune with minimum fuss.I'm not sure if its the way i play or the strings but i haven't managed to snap one yet either (the other reason i haven't changed them) and everything still sounds amazing.the only downside there was upon their release (i'm not sure this is still applicable) was that they were a little more expensive than standard strings.also all cobalt strings came (again not sure if still relevant) in the same colour packet making it hard to tell at a glance what gauge you had.all in all they are fantastic strings and i will always carry at least an extra set for the day that a string does eventually give in.

bit expensive but sound really good last well and theses are the ones i only use

Play and sound great

Sounded great initially. Played 2 gigs and thought I'd found the perfect strings - felt great, nice punch and brightness without being too bright. I always wipe the strings down after playing. Pulled the bass out of it's case a couple of weeks later and noted that the strings felt sticky. On closer inspection it seems that parts of the strings have what appears to be rust patches. I have tried to clean them up but basically these are now unplayable. Disappointed to say the least and a total waste of money - these things aren't cheap, especially if you can only get a couple of gigs out of them.

I've bought a packet of these strings twice now (one for each bass). They're the best set of strings I've ever used on bass. The high ends are bright and the low ends are nice 'n' crunchy too. These strings will cut through the mix and offer a phenomenal bass tone overall. They're comfortable to play with and definitely worth the money in my personal opinion. I can't recommend these enough.

I love those strings but unfortunately sting 130 broke when I was tuning it to B sound. I dunno why but it happened...

I've played bass for over 40 years and have tried most of the brands at various times. I have to say these are definitely the best both in terms of the new sound and longevity. Very bright if you're into that but they also have a strong fundamental so no issues if the vintage sound is what you're after. Expensive to buy but given the long life they're definitely great value

Ernie Ball strings just sound good and they're not super expensive.

Muy buenas cuerdas, no había probado estás Ernie Ball de cobalto y suenan excelente, si se nota la diferencia entre las normales Slinky y estás, suenan muy brillante. Siempre he sido muy de esta marca y no decepcionan. Recomendadas.

Nice bright sound and great attack. Typical Ernie ball. I have been an Ernie ball user since 1988.

Sin duda alguna cumplen a la perfeccion lo que prometen, es maravilloso el sonido que proporcionan!

This is my go-to string. I will go back and forth between Ernie Ball Super Slinky (a little brighter) and Slinky Cobalts. I like the Cobalts as I find them more responsive, better all round performance, and they seem to last a little a little longer before some ugly harmonics kick in letting me know when I need to change. A little more expensive from Amazon than other vendors, but I usually get them in the next day or two after ordering. Great product!
