Enhanced output. Incredible harmonic response. Increased low end Crisp, clear highs Engineered to maximize output and clarity, Ernie Ball Cobalt Slinky guitar strings are one of the latest innovations in string technology.

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 Β£2 or so. ## Features - Cobalt produces a stronger magnetic relationship between pickups and strings, resulting in increased output. - Cobalt electric guitar strings provide an extended dynamic range, incredible harmonic response, strong low end, and crisp, clear highs. - Wound strings consist of Ernie Ball’s Cobalt alloy wrapped around a tin-plated high-carbon steel core wire. - Extra Slinky brings extra light tension for fast and easy play across the fretboard. - Made in the USA. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B007NCVWNW | | Best Sellers Rank | 582 in Musical Instruments & DJ ( See Top 100 in Musical Instruments & DJ ) 50 in Guitar Strings | | Body Material Type | Steel | | Brand | Ernie Ball | | Brand Name | Ernie Ball | | Coating Description | uncoated | | Coating description | uncoated | | Colour | Extra (8-38) | | Country of Origin | USA | | Customer Reviews | 4.6 out of 5 stars 9,997 Reviews | | Finish Type | Uncoated | | Global Trade Identification Number | 00749699127253 | | Included Components | Guitar Strings | | Instrument | Electric Guitar | | Item Type Name | Electric Strings | | Item Weight | 0.04 Pounds | | Manufacturer | Ernie Ball | | Manufacturer Part Number | 2725 | | Material Type | Steel | | Model Name | Extra Slinky | | Model Number | P02725 | | Product Warranty | None. | | Recommended Uses For Product | Electric Guitar | | Set Name | Ernie Ball Extra Slinky Cobalt | | Sound Profile | Balanced with slight emphasis on lows and highs | | String Gauge | Extra Light (.008, .011, .014, .022w, .030, .038) | | String Material Type | Cobalt | | String gauge | Extra Light (.008, .011, .014, .022w, .030, .038) | | String material type | Cobalt | | UPC | 749699127253 | | Unit Count | 1 count | ## Product Details - **Brand:** Ernie Ball - **String gauge:** Extra Light (.008, .011, .014, .022w, .030, .038) - **Colour:** Extra (8-38) - **Instrument:** Electric Guitar - **String material type:** Cobalt ## Images ![Ernie Ball Extra Slinky Cobalt Electric Guitar Strings - 8-38 Gauge - Image 1](https://m.media-amazon.com/images/I/81UTEdg5WJL.jpg) ![Ernie Ball Extra Slinky Cobalt Electric Guitar Strings - 8-38 Gauge - Image 2](https://m.media-amazon.com/images/I/31-crG-9fhL.jpg) ![Ernie Ball Extra Slinky Cobalt Electric Guitar Strings - 8-38 Gauge - Image 3](https://m.media-amazon.com/images/I/919fLwnXPML.jpg) ## Available Options This product comes in different **Color, Style** options. ## 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.
