I have an acoustic dreadnought and have been experimenting with different brands and sizes of strings. My guitar came with 13s and I learned with them. I tried some 11s and 12s to see about quality, durability, sound, feel. These so far have out paced all others. I could tell right out of the package while putting them on the guitar that I was going to like them. They felt magical as I unwound them. I put them on the guitar, tuned it up, strummed a few songs, retuned them and absolutely fell in love with these strings. They are smooth, light, a rich and creamy tone and very nice on the fingers. Now, I'm no professional by any means, but if I were, I would go with these as my go-to strings. If you are an 11 player, try these. They are super great.
