## Overview

Ernie Ball Primo Slinky Cobalt Electric Guitar Strings (9.5-44 gauge) deliver superior magnetic pickup response and extended dynamic range thanks to their patented cobalt alloy construction. Designed for professional-level clarity, durability, and playability, these medium gauge strings offer a perfect balance between tone and feel. Made in the USA, they are the go-to choice for guitarists seeking cutting-edge performance and reliability.

## Description

Designed for maximum output and transparency, the Ernie Ball Cobalt Slinky guitar strings are one of the latest innovations in string technology. To provide guitarists and bassists with a current voice, Cobalt strings offer extended dynamic range, incredible harmonic response, increased bass range, and crystal clear, transparent treble. Cobalt provides a stronger magnetic relationship between pickups and strings than any other alloy available so far.

Review: Hands down, the best strings I've ever used - I've tried every brand of string, known to man and settled on Ernie Ball Slinkys for years. I tried some Cobalt strings a year ago and haven't used anything else since. They're even better than Slinkys. I prefer the feel of the wound strings. The wound strings sound a bit fuller and whilst marginal, they seem to last a bit longer. The unwound strings are the same as you get in Slinkys. Well worth the extra £2 or so.
Review: Trust the Hype - Been playing about 4 years, used all sorts of strings from Elixir coated to EB standards and other premium strings. Coated were my favorite originally until I realised the coat actually does more damage than good as the strings begin to age. I was kind of lost till I ordered these. The only patented cobalt strings so you can't get these under any other brand name. The material genuinely does make a difference in terms of sound and response from the pickups. Playing feels easier, the strings feel a lot nicer, probably more so than any coated strings I have tried, great for slides/bends. They hold their tuning great after very little stretching and they seem to be a lot tougher than usual strings despite seeing the odd review claiming to have snapped the e string but I'm more inclined to believe that is down to being too eager when tuning. Overall amazing strings and worth every penny just for the sound and the playability aspect. I'll never be going back to non cobalt guitar strings after the experience.

### ⭐⭐⭐⭐⭐ Very good strings
*by A***R on 21 October 2024*

I’ve not tried this particular one before, usually opting for the Ernie ball 9’s ( pink pack) but I wanted to try the 8’s , they are pretty good to be fair , not broken one ( yet , and I do tend to dig in a bit) stay in tune very well, ( after a good stretch) good sound and a decent price, will buy again, not had them long enough to rust yet, but I play every day so that’ll keep it down
