The Elixir Strings PolyWeb 10-47 are a set of acoustic guitar strings, with the gauge mentioned in the title. The PolyWeb set of strings comes in any gauge sizes, but I prefer having 10’s on my acoustic. I’ve used these PolyWeb strings primarily on my Martin and Guild acoustic guitars, but I don’t see why these wouldn’t be suitable on any acoustic guitar. I don’t really know what the difference is between the PolyWeb series of strings and the NanoWeb strings, as I’ve only used the PolyWebs. The Elixir Strings PolyWeb 10-47’s have an overall bright and vibrant sound, perfect for acoustic guitars where you’d want this type of sound rather than something a bit darker. The feel of the strings is about average, as I don’t notice too much of a difference between these and other sets of acoustic guitar strings. The PolyWeb coating on these strings definitely does allow them to last a good amount of time, as I’ve noticed that these definitely stay fresher on my guitar than most other sets of acoustic guitar strings that I’ve used. I guess that’s what the PolyWeb coating will do for you over anything else. The price of these strings compares pretty well to other sets of strings, as they’re definitely the same ball park as most sets of strings out there. Price shouldn’t be a main factor with strings, as comfort and sound should be the main priorities, as strings in general are cheap enough that it doesn’t really matter. Many sets of strings will sound and feel similar, so the fact that these strings seem to last a bit longer is definitely a main selling point in my opinion. I’d definitely encourage those who play a lot of acoustic guitar to give the Elixir Strings PolyWeb 10-47’s a shot.
