So I am a bit impressed. My situation- I got these thinking the extra magnet and extra slinky attributes would help out my Harley (Fender Sonic Mustang wanna be) as it is a 24 scale and my wife already has the later one and this was cheaper - for basically if and when I take lessons because of the shorter scale length b/c the teacher can put me thru some runs, hammer ons with my pinky etc... You know Harley Benton has a tendency to sound muddy, so thought the extra magnetic drive wouldnt hurt. So... The strings as I was installing them stuck to the pickups b/c the magnetic pull was that strong, and are very slinky AND a bit beefyer fatter to the touch and I liked that too! Sound very good! Most likely from the magnetic quality. ### ⭐⭐⭐⭐⭐ Magique *by on Reviewed in France 16 February 2024* j'ai pas un haut niveau, je joue depuis 2ans, et au debut j'utilisai les cordes de la marque Ibanez, mais elles cassaient régulièrement (1/mois), puis je trouvais le son brouillon... J'ai testé celle-ci voulant un son plus cristallin (même dans l'énervé !) et je suis tombé sur le cul... Le son est précis, ça respond au poil , et ça tient ! j'attend de voir mais déjà 3mois sans soucis à bender et à attaquer :) Le must pour ma part ### ⭐⭐⭐⭐⭐ Beste Saiten ever *by on Reviewed in Germany 17 April 2026* Die Saiten ergeben ein harmonisches, klares Klangbind, das Verstimmen hält sich echt in grenzen hnd die Spielbarkeit ist super, auch beim Bending gibt es keine Einschränkungen. Der Klang ist druckvoller und hat mehr Sustain, die Saiten sind dicker 010er und trotzdem sehr gut spielbar. Doch, rundum ekne Verbesserung. ## Frequently Bought Together - Ernie Ball Super Slinky Cobalt Electric Guitar Strings, 9-42 Gauge (P02723) - Ernie Ball Super Slinky Classic Pure Nickel Electric Guitar Strings, 9-42 Gauge (P02253) - D'Addario Accessories Pro-Winder Guitar String Winder, Cutter, Bridge Pin Puller - All in One Guitar Tool - Black --- ## 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.sn/products/260171874-super-slinky-cobalt-electric-guitar-strings-9-42-gauge](https://www.desertcart.sn/products/260171874-super-slinky-cobalt-electric-guitar-strings-9-42-gauge) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-07-06*
