A list of its players reads like a Jazz Hall of Fame, and it’s still the undisputed king of flat wounds, for many of today’s jazz greats. A true flat wound (not a “ground wound” or “compressed wound” like some of the pretenders) with glassy smooth polished nickel winding on a round core, it has the perfect balance of fundamental to overtones required for traditional jazz. Some players claim that its mellow, powerful tones actually improve with age! Review: Brilliant sound - Brilliant I’ve never put 12,s on jazz guitar wow what a difference !

Big thumbs up from me. **Q: Hi everyone, Anybody ever tried these flat wound jazz swing JS112 on an electro acoustic guitar with good results?** A: Not tried on an electro acoustic , but I would imagine they would be too heavy and would possibly warp the neck. More suited to an archtop - I use them with good results on a Yamaha AEX 1500. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Brilliant sound *by M***N on 27 September 2025* Brilliant I’ve never put 12,s on jazz guitar wow what a difference ! ### ⭐⭐⭐⭐⭐ Very good indeed *by M***A on 22 November 2025* Best strings I’ve ever bought very long lasting second purchase ### ⭐⭐⭐⭐⭐ Great tension and smooth playing *by B***N on 30 December 2025* Great tension and smooth playing ## Frequently Bought Together - Thomastik Strings for Electric Guitar Jazz Swing Series Nickel Flat Wound Set JS112 Medium Light .012-.050w - Thomastik Saiten für E-Gitarre Jazz Swing Series Nickel Flat Wound Satz JS111 Light .011-.047w,silver - Thomastik Saiten für E-Gitarre Jazz Swing Series Nickel Flat Wound Satz JS110 Extra Light .010-.044w --- ## 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.vu/products/49141219-thomastik-676727-strings-for-electric-guitar-jazz-swing-series-nickel](https://www.desertcart.vu/products/49141219-thomastik-676727-strings-for-electric-guitar-jazz-swing-series-nickel) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-06-05*
