## Overview

Ernie Ball Primo Slinky Cobalt Electric Guitar Strings (9.5-44 gauge) leverage cobalt alloy technology to enhance magnetic pickup interaction, delivering louder, clearer sound with extended dynamic range and harmonic richness. Designed for professional guitarists seeking a balanced gauge and superior tone, these uncoated strings are crafted in the USA for durability and premium performance.

## 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: Loud and clear, something new you should try once - A lot louder than the rotosound or elixer. Took an extra few days to get used to, they're cobalt so something new that's going to need breaking in longer. I would probably go back to elixer for smoothness and ease of play . They're a bit tougher to play but they're definitely worth a try.
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.

### ⭐⭐⭐⭐⭐ Hands down, the best strings I've ever used
*by A***R on 19 July 2025*

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.

### ⭐⭐⭐⭐⭐ Bright and loud
*by D***O on 29 June 2024*

I’m not too experienced in choosing new guitar strings but I thought I’d give these a go. They are really bright and loud and i definitely can hear and feel a difference. I took a risk and used them on stage at a gig and they performed perfectly and I didn’t even need to ‘break them in’. I tend to play lots of genres but more focused on metal and these strings are perfect. Definitely recommend them 👍.
