## Overview

Ernie Ball Skinny Top Heavy Bottom Slinky Cobalt Electric Guitar Strings (10-52 gauge) combine innovative cobalt alloy technology with a hybrid gauge design to deliver superior magnetic pickup response, extended dynamic range, and a perfect balance of shred-friendly tops and thick rhythm bottoms. Made in California, these strings offer enhanced durability and tonal clarity favored by professional guitarists seeking both precision and power.

## Description

Engineered to maximize output and clarity, Ernie Ball Cobalt Slinky guitar strings are one of the latest innovations in string technology. Seeking to provide guitarists and bassists with a new voice, Cobalt strings provide an extended dynamic range, incredible harmonic response, increased low end, and crisp, clear highs. Cobalt provides a stronger magnetic relationship between pickups and strings than any other alloy previously available.

Review: Hefty strings for a new buiild - I got these to go with a build I did and they are tremendous sounding. I usually use another brand, but these Cobalt strings got me doing a second listen for sure. They're kind of thick, considering I usually use 9-42, but the tone really comes out with the Invader Single Coils I got from SD. Being a little thicker I do notice they have a longer wear in time. They keep a tune while playing, and rarely have to check the tuning during sessions... if I didn't want to.
Review: Love them now - I had bad luck with string breakage on some of the first runs of these. I'm glad I gave them another try after some time. No more breakages and the sound is amazing. A little extra grit and output at the same gain level and very harmonic (some may not like that I guess as it does accentuate pick chirp a bit). The feel is a bit different, but I love them. I hope they make them forever.

### ⭐⭐⭐⭐⭐ Hefty strings for a new buiild
*by S***N on March 23, 2026*

I got these to go with a build I did and they are tremendous sounding. I usually use another brand, but these Cobalt strings got me doing a second listen for sure. They're kind of thick, considering I usually use 9-42, but the tone really comes out with the Invader Single Coils I got from SD. Being a little thicker I do notice they have a longer wear in time. They keep a tune while playing, and rarely have to check the tuning during sessions... if I didn't want to.

### ⭐⭐⭐⭐⭐ Love them now
*by K***H on October 15, 2024*

I had bad luck with string breakage on some of the first runs of these. I'm glad I gave them another try after some time. No more breakages and the sound is amazing. A little extra grit and output at the same gain level and very harmonic (some may not like that I guess as it does accentuate pick chirp a bit). The feel is a bit different, but I love them. I hope they make them forever.

### ⭐⭐⭐⭐⭐ These are Expensive, but worth the extra money in both Feel and Tone
*by G***Y on September 13, 2013*

These cost about double the standard strings in equivalent gauges, but they play exceptionally well and sound great. I tried them out after reading reviews from several artists who stated that they feel broken in out of the bag and I agree. Bends and vibrato seem easier to me with these as they don't feel stiff like many new strings do. The tone lasts for a long time, but they do gum up with the finger grunge and become slightly discolored after a moderate amount of playing. A quick wipe with lemon oil or guitar polish will clear up the grunge and the sound remains nice and full longer than others despite being darker where you play a lot. If you don't like having to play for a week or two to get that broken in feeling, these are great and the tone is warm and full for a long time. I keep mine on for about twice as long as the standards, so the extra cost works itself out without as many string changes.
