    • Quality at Value Price
Style: Extra Light (10-50) Size: Single Pack
I strung these on a Parlor guitar - I really like the sound they give the small bodied guitar. Sounds rich and full. Also easy to play. I think the longevity is also really strong. I have had them on a long time and I feel they sound equal or better than when I just put them on. I am just a casual player - but I really think these are quality at a value price. ... show more

    • crisp sound, great value
Style: Extra Light (10-50) Size: Single Pack
I've been using Elixir strings for many years before I decided to give these a try. While not as long-lasting as the Elixir's, they produce a lovely and crisp sound on both my cedar-top and spruce-top acoustic guitars. They stay in tune after properly stretching them. Some reviewers reported that these strings break easily, but I had no problems even when using thick picks and hard strumming techniques. I noticed that they are louder than the Elixir strings I've been using for years. They are a great value and I'll buy them again. ... show more

    • Nice tone and flexibility

Had some doubts since I'm a devout follower of daddario 10-47s. But now I'm a believer. These have a nice tone

    • High E broke twice but the rest sound great
Style: Extra Light (10-50) Size: Single Pack
I got 2 sets of the extra light strings to restring my guitar, just in case a string broke. What I wasn't expecting was for the high E strings from both sets to snap just from me holding them taut to begin turning the tuning pegs! The other strings were able to be held taut by my hand, but those little E strings are extremely delicate! I'm really baffled on how to get them tuned up. If just my hand is enough to snap them, I'm pretty sure the tension of tuning them will be way too much. I'm getting 1 final set of the extra light strings and going to be extremely careful with the little E string and tune it gradually over several days. I'll update this if I'm able to get it working. ... show more

    • Great bright tone for the money
Style: Extra Light (10-50) Size: Single Pack
I love the hybrid gauge assortment. 10’s give you nice crisp highs and the .50 for the low E really booms out on the bass end. They don’t last terribly long in sound quality but I usually change my strings monthly anyway. Once the bright color on the finish starts to tarnish away it’s time. I do play a lot. 1-2 hours every day. They sound amazing and they’re pretty easy on the fingers. ... show more

16 God so loved the world that he gave his one and only Son. Anyone who believes in him will not die but will have eternal life. 17 God did not send his Son into the world to judge the world. He sent his Son to save the world through him. John 3:16,17 NIRV 18 Whoever believes and has decided to trust in Him [as personal Savior and Lord] is not judged [for this one, there is no judgment, no rejection, no condemnation]; but the one who does not believe [and has decided to reject Him as personal Savior and Lord] is judged already [that one has been convicted and sentenced], because [b]he has not believed and trusted in the name of the [One and] only begotten Son of God [the One who is truly unique, the only One of His kind, the One who alone can save him]. John 3:18 Amplified Bible 15 And if anyone’s name was not found written in the Book of Life, he was hurled into the lake of fire. Revelation 20:15 Amplified Bible Revelation 20:15 Since everyone who goes before the great white throne is to be tried and sentenced for his deeds, and no one is sinless, the only way to escape condemnation and the “lake of fire” is to have one’s name in the “Book of Life” through authentic faith in Jesus as Lord (see Ps 69:28; Phil 4:3; Rev 3:5).
