Made in Austria. The silk thread on the ends of the strings help guard against rubbing on the tailpiece as well as providing a better grip in the tuning pegs. I can’t believe how well my guitar stays in tune compared to using the classic round wounds. I put them on, tuned up and nearly stayed that way from the start.The 11 gauge are a great way to transition from round wounds if you’re new to flats, and are less drastic of a change. The 11’s are as similar to 10’s as you can get with flats and the wound G takes away that sharp, pinging G string sound. Flats will reduce string sliding noise and they sound a bit more mellow than rounds. Jazzy, vintage and great for finger style.If you want a very quality set of strings, these Thomastik-Infelds are beautiful and will last a long time, worth the investment for me. No they’re not cheap, but if you have a nice guitar and you want strings to stay in tune, these are THE string of choice. ### ⭐⭐⭐⭐⭐ Great strings! *by on Reviewed in the United States August 10, 2026* I have been experimenting with strings ever since I bought an Eastman hollow body. I was turned on to flat wound, that aspect of the strings I was trying would never change. After trying various versions of strings offered by different companies including the George Benson strings made by Thomastik-Infeld (the George Benson strings were too heavy for me), these strings are a clear winner for me. The sound is rich and full, and my fingers glide across the strings. I have found the strings I will be using from now on. ## Frequently Bought Together - Thomastik-Infeld Jazz Swing Guitar Accessory - Flatwound Acoustic Guitar String for a Rich and Warm Traditional Jazz Guitar Sound - Thomastik-Infeld Jazz Guitar Swing Series 6 String Pure Nickel Flat Wounds E, B, G, D, A, E Set (JS110) - Thomastik Jazz Swing Series Guitar 6 String Pure Nickel Flat Wounds E, B, G, D, A, E Set (JS112) --- ## 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.be/products/1363700-jazz-swing-guitar-accessory-flatwound-acoustic-guitar-string-for-rich](https://www.desertcart.be/products/1363700-jazz-swing-guitar-accessory-flatwound-acoustic-guitar-string-for-rich) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-08-24*
