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.
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.

## Features

- One of the original Slinky gauges, Super Slinky has remained one of the most popular electric guitar strings for decades.

## Questions & Answers

**Q: What is the difference between the Power and Super strings?**
A: Power Slinky are 2 standard gauges thicker than Super Slinky. So the only difference is the thickness of the strings.

**Q: Can these be used in drop b on a les paul style guitar**
A: I've used them drop c on my les paul and not too bad

**Q: Will these work on an acoustic guitar**
A: I always use Ernie Ball .009 -.042 on my acoustic as I like light strings and they keep a good tone for weeks.

**Q: I understand only the 4th, 5th and 6th are coated. The plain strings are the same as a normal SS pack. Is that right?**
A: Hi, These aren't coated strings. They are made of cobalt which reacts with the pickups a bit more to increase output. The 4th, 5th and 6th strings are made with cobalt but the plains are standard ernie ball plains. Thanks EmileStrings Direct

### ⭐⭐⭐⭐⭐ 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. The unwound strings are the same as you get in Slinkys. Well worth the extra £2 or so.

### ⭐⭐⭐⭐⭐ Edgy tone with superior projection in the mid-range.
*by M***N on 16 June 2022*

The Cobalt strings suits some instruments/styles more than others; there's more crunch & grind than regular nickel, but not quite as much as stainless steel, which are arguably the best choice for bright metal tones. I loved the sound of the Cobalt strings installed on a T-style guitar, using clean tones and especially using mild to moderate crunch sounds. There's a noticeable difference as compared to, let's say, EB Regular Slinky. However, I tried them on a 335-style guitar (which I use for jazzier and more r'n'b styles), and the Cobalts were perhaps a bit too edgy sounding, although of course you could turn down the tone control on the guitar on the fly if desired. Kind of the same using an S-type guitar (with a Zero-Load Tone pot), the edginess was perhaps a little too aggressive sounding, but if edgy aggression is what you want, then Cobalts are ideal. In summary, I use Cobalts on one of my S-type guitars (not used in the accompanying video) which benefits from the extra edginess and the slightly increased output, but I use EB Paradigm on my 335-style guitar and also on my already bright sounding other S-type guitar (which had D'Addario NYXL 9–42 strings installed for the accompanying video demo, but I much prefer 10–46, which is my usual choice, and like I say, EB Paradigm is my preferred choice for that instrument). Cobalts are cool!
