Sound amazing

Reviewed in the United States on March 18, 2024

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

They sound amazing. Punchy, with tight lows. Top end is bright. My only complaint is that they feel a little sticky compared to other Slinky strings; they are similar to how stainless steel strings feel. I can live with that, given that they sound so good.

Fantastic tonality, holds up to tuning changes (excellent for drop tunings), longest lasting strings I've gotten for heavy use as far as roundwounds go.

Amazing tone but they do not last

Reviewed in the United States on April 4, 2024

Color: Power (55-110)Style: 4-StringVerified Purchase

I LOVE the tone of these strings. If you need the Mike Dirnt sound, this will get you there with most Fender-style bass guitars. I often tell people to try these before they change their pickup. Unfortunately, they are expensive, and the tone lasts about 2 months before the strings are dead like as a doornail. I have switched to Exlier's for longevity but I miss being able to make the Longview tone on command.

Great strings but use caution

Reviewed in the United States on February 13, 2023

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

I went to buy a replacement set as I had been using EB Cobalts for a while now. I noticed a "used" set posted in original packaging and in good condition, so I thought I could save a few bucks and break-in time. Unfortunately, the "E" was already unraveling and the original buyer returned them and Amazon resold them. Once the outer ribbon starts unraveling they're no good. The original buyer had cut the string, probably before bending it, and it unraveled. Good for the buyer, bad for me. I requested a return and ordered a "new" set. That set came the next day and worked great! Lessons learned, 1) don't buy used strings, 2) bend before cutting or wind the whole string(looks unsightly I know) and 3) buy Amazon as they back their products and mistakes.

My go-to String

Reviewed in Canada on September 23, 2022

Color: Regular (45-130)Style: 5-StringVerified Purchase

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!
