Ernie Ball Skinny Top Heavy Bottom Slinky Cobalt 7 String Electric Guitar Strings The Ernie Ball Cobalt strings are another evolution in string technology and give the instrument a new voice. Cobalt is more magnetic than nickel, so these strings offer the maximum output, higher dynamics, more harmonic resonance, rich bass and crisp treble. Because cobalt is more robust than nickel, the Ernie Ball Cobalt strings are more durable than traditional strings. Thanks to the soft and silky feel, string bending is also child's play. Slinky cobalt strings are nickel free. Review: Tell me you’re into heavy metal, without telling me you’re into heavy metal... - I actually used this on my 6 string and it handled drop G#, no problem.

They rusted badly very quickly. The sound is also quite abrasive by design and were too tight for my liking. But then they are meant for an aggressive attack if that is the sound you are after. **Q: Are these suitable for B standard and Drop A tuning?** A: Yeah man, perfect to go down to Drop G as well **Q: Will these go to drop A tuning?** A: Yes, but as usual expect s slightly looser tension in the string. Buy yeah they're great for drop A, I use them exclusively in drop A ## Customer Reviews ### ⭐⭐⭐⭐⭐ Tell me you’re into heavy metal, without telling me you’re into heavy metal... *by R***T on 25 April 2021* I actually used this on my 6 string and it handled drop G#, no problem. All the heavies. Much djent. Pick-up-a-pancake. ### ⭐⭐⭐⭐⭐ Holds up well to use *by V***A on 15 November 2025* I always get these for the 7, great feel and they last well with repeated use. ### ⭐⭐⭐⭐⭐ Get these if you have a 7 string *by S***N on 19 February 2020* More and more I've recently been gettings severely miffed with my entry level LTD 7 string, even to the point of thinking about selling it. The low B was too floppy and a nightmare to tune and the whole guitar sounded dull. This was a last ditch attempt to make me like the 7 string, so I chose this set, being heavy at the bottom end and the same gauge as my 6 string at the top. They've made the whole guitar sound like a different instrument entirely. No more floppiness on the low B, tuning stability vastly improved and everything feels far more tight and precise. Not sure how people who prefer a light gauge would find the lower end strings, but being a bass player as well, it wasn't a problem for me. Sticking with these strings from now on. ## Frequently Bought Together - Ernie Ball 7-String Skinny Top Heavy Bottom Slinky Cobalt Electric Guitar Strings, 10-62 Gauge (P02730) - Ernie Ball Skinny Top Heavy Bottom Slinky Cobalt Electric Guitar Strings, 10-52 Gauge (P02715) - Ernie Ball Skinny Top Heavy Bottom Slinky Nickel Wound Electric Guitar Strings 3-pack, 10-52 Gauge (P03215) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/48493824-ernie-ball-skinny-top-heavy-bottom-slinky-cobalt-7-string](https://www.desertcart.tn/products/48493824-ernie-ball-skinny-top-heavy-bottom-slinky-cobalt-7-string) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-06*
