The price and quality of the instrument has little to do with whether or not you'll be using these strings. I usually get them for 13 bucks out the door including 2nd day shipping and tax. This guitar needs it though. If you have a lightweight guitar I'd advise a lighter string because too much pressure could possibly break the head of the guitar. I used Elixir Nanoweb Custom Lights which are 11/52's. However, what is best - custom light or light? I go the other way from HD Lights, which are essentially a light set with mediums on the treble side. Custom light strings are a tad bit less thick. Guitar bridge pins come up slightly when tuning?

You’re outta luck if you want a seven string set, as you can only get that in the Nanoweb series. I do think the heavier polyweb coating dampens the vibrations a little bit more. They really help when finger picking to get the high E and B strings to ring out. It's not night and day, and it really seems to be more of a "feel" thing to me that pure tonal, but I dig them. So Elixirs got these new HD Lights which is guage .13-.53 instead of the regular lights .12-.53. You will need to have the exact same gauge (string thickness) on the sets, as heavier and lighter sets will sound and play differently. Feels comfortably smooth and reduces finger squeak. But more importantly to me is they handle DADGAD and open tunings great. How expensive is your Epiphone acoustic? Armstong got his break playing for an all-white audience on broadway as part of a black review called what. As a semi-new acoustic player, I've asked around and have been told that Elixir light strings are best for my acoustic. The nanoweb coating is thinner, and you will have to test both to find what suites you better. ? http://www.elixirstrings.com/products/additional-i... http://www.elixirstrings.com/products/product_acou... http://www.acousticguitarforum.com/forums/archive/... for a guy, what is the difference between a fantastic chick and just average? However, lighter strings also don't sound out as loud. I like the tone of Elixir HD Lights but I don't like the extra effort they take to play compared to regular Elixir Lights. Anyways, custom light vs. light -- it's a matter of the thickness of the strings. The less thick strings are, the easier they are to play. Thanks! And I love them. It's all about sound, and the guitar you are using. Thanks. You can sign in to vote the answer. I have them on almost all my non-12 stringers. I just order them on amazon.
