  1. Julian Gonzales

    The best guitar strings

    D’Addario Strings are the best that I’ve owned.

  2. Robert D.

    Great tone for a Newby

    I’ve started using these strings on a cheap Yamaha F335TBS and I’m really amazed at the difference from the factory strings. I’m a new player working my way towards getting better. I try to play 6 days a week for 45+ minutes so they’re “dulling up” after about 2 months but I’ve got no complaints. I feel like it’s a good deal for the price.

  3. KyleKyle

    Easy to string and sound great!

    I’ve been using these strings for only a few months so time will tell how long they last but wow they sound so clear! I’ve never strung my own guitar until I ordered these, super straight forward and easy to do. Simply put, I’d definitely recommend this product.

  4. Christopher S Peiser

    Maybe it’s just the gauge

    I don’t like these strings at all. I have been having a very hard time finding strings that sound good and feel good. These feel like they are rubber bands and sound just as bad. Maybe I just need a heavier gauge.

  5. Anthony tobio

    Excellent guitar strings 40 years of playing. Excellent delivery thank s

    Playing guitar … These guitar strings are really great Bronze and sound the best for live playing …. Changing strings for Beginners is difficult until they learn about strings.

    Great item. Great price

    Exactly what my son wanted. Fast shipping. Great prices.

  8. W. Taylor

    Excellent guitar strings!

    Bright, full sound with long lasting tone. I change my strings every 3-4 months weather they need it or not and they never really have. They always sound “still new”. I’ve tried other brands and none sounded as good as these, and all of those were changed in less than three months. These strings tend to cost the same or less than other brands but never better. Finally, Epiphone Masterbuilt come with this brand of strings. As you probably know Epiphone is a branch of Gibson guitars. These are the strings they chose.Give them a try!

    Great sound, middling longevity

    The strings sound great – slightly bright and more “full” than a cheaper string. That being said, I come from a typical Elixer guitar string background and find that virtually every other string kind of stinks for longevity and playability. While these strings sound great and would be fine for maybe 1 week of playing, I wouldn’t recommend using them for anything professional beyond that – I’d be restringing my guitar weekly if I relied on these strings. They’re more cost-effective than Elixers but they last maybe 1/4 of the time as their brightness does wear off (a typical D’Addario experience IMO). Very good strings for a specific window of time.

  10. C

    Easy to use and work great!

    We have purchased these before and my son loves them. He just started playing guitar last Christmas and has really picked it up nicely. He said these are easy to use and change out. The quality is excellent too & way nicer than the strings his guitar came with. Very happy with purchase!

  11. Wayfinder

    Highly recommended. Very good strings.

    I usually play classical (nylon string) guitar, but have an Ovation deep-bowl acoustic electric as well and after the original strings wore out, I never have found strings that I really liked (don’t ask me why I never thought about contacting Ovation and asking them what they use from the factory. One of those duh things I didn’t even think of until just now).Based on reviews and questions answered here on Amazon, I purchased this triple-set of strings. Instant gratification. First, they tuned up quickly and retained their tune on a relatively respectable basis (no new string holds tune perfectly for the first couple of days, but these retained tune fairly well). The sound is excellent, the playability comfy. The tone of my Ovation was back.Here are my itemized observations:* First, three sets for $13 (currently). Cannot beat the value for price.* BRILLIANCE. What many people call “bright”, brilliance is the opposite of “dull”. Some strings sound dull right out of the package. These strings are brilliant, bringing out the full tone and maximum volume from the guitar.* TONE. The natural tone of the guitar is allowed to shine through, no hint of “tinniness”, “plunk” or “twang”.* MELLOW. Mellow is difficult to define, but the best definition I’ve heard is, “Ah, that sounds nice.” Mellow is a string settling into a guitar and becoming part of the guitar. It’s a pleasantness that doesn’t grate on your ears when you pluck a string. These strings are medium-mellow, just enough to allow one to enjoy the sound without falling asleep. : )* BALANCE. At first the E overtoned the b and e. But as the strings settled that became less pronounced and the strings balanced right out. The trebles became clearly audible while the E and A provided just the right touch of bass.* COMFORT. The 12-53mm diameter of these strings is comfortable to the fingers. Thicker strings are often more difficult to play and can even damage some guitars. Lighter gauge tends to cut into the fingers unless the guitar has excellent action. These strings are just right– especially the 53mm E, which provides the proper amount of bass without overkill or difficulty in strumming.SUMMARY: These are excellent strings, which doesn’t surprise me since I’ve use D’Addario classical guitar strings for years. Martin and GHS are both good strings, but somehow D’Addario just shines.Thanks to Amazon enthusiasts who helped me decide to give these a try. Highly recommended.

    a Fine All around Acoustic string.

    i’ve used Thousands of set’s from this Manufacturer, and these work just fine!!i would have given a full 5 on everything, buy i do find them a bit Too brightover “Martin phos. Bronze”.. but after they get some play time on them they mellow.

  13. Andrew Glivic

    Good for what it is

    I’m getting older and thought I’d try these very light strings. They are easier to play. I have a high frequency hearing loss and notice the tone disappearing after 2 to 3 weeks of intermittent playing. I put on 11’s yesterday and the tone of the slightly heavier strings was noticeably better right out of the box. So if you just want a light string to practice on, and you don’t mind changing them frequently, these will work. If you plan to play in front of an audience, I would recommend something heavier to insure a better tone. Cheers

    Good strings

    Usually I purchase this type of string, I find it to be best quality and sound for the price.

  15. A Photographer

    Great value, the 3% extra tension really helps!

    For as long as I’ve been playing acoustic guitar (sporadically over the past 15 years) I’ve always had a set of these. Recently I was using D’Addario 80/20s because that’s what my new acoustic came with, and while I liked the tone, they do tarnish quickly and were gouging my fingertips (I’ve just gotten back into acoustics and have electric guitar calluses from the much thinner 9 gauge). So I figured I would see what the difference between the 80/20s and the phosphor bronzes were like.At first I didn’t like the phosphor bronze’s tone, but after having them on for a week I now love what I’ve heard described as “warm and buttery” with just enough sparkle and long sustain. I love the rose-gold look, and they tarnish much less quickly than the 80/20s, almost as if they’re coated. Speaking of which, the gouging in my fingertips has decreased dramatically since installing these. I’ve read that these have 3% more tension than the 80/20s, and that extra stability seems to be helping tremendously in forming my calluses correctly. I’ve tried DR Rares and thought they had too much tension (as advertised); these are just right. Still playable, bends easy, solid, dependable.Some guitars sound better with different strings, but I would say you should always at least try one set of these. They’re affordable, come in packs of 10 (making them even more affordable), have corrosion resistant packaging and helpful ball end colors, and you get D’Addario’s Players Circle bonus points with each set. I may try other strings in the future, but will probably be sticking with these.

    Good but broke

    I think that these strings are indeed good, and I do believe that these are the best BRAND of strings but get medium gage because these snap early. Also these snapped while i was setting them up for no reason.

  17. Robert Grinis

    Twelve strings not six

    Be sure to get the right stringsfor your guitar.

  18. Dave

    IMHO the best acoustic strings sold at any price

    I will keep this short. The price is unbelievable, it’s nice to have three sets in a box and these are the best acoustic strings on the market. That’s only my opinion and everyone has one……so many will disagree.I have an regular acoustic and an acoustic electric and strung both with these strings. It made each guitar sound like a 3 thousand dollar guitar. I find that most inexpensive guitars have cheap strings, most can be vastly improved with something as simple as new strings. I really believe in these strings. When I find a good thing, I am hooked and I will not use anything BUT these on anything acoustic. On a guitar, strings are everything. The tone feel and bend is what’s important. These are very light and VERY easy on the fingers, unlike clunky stock strings on most acoustics. I guess they think you need big, think strings to produce volume….not so. Some will disagree saying they break if they’re too thin. I would rather have a shorter life with strings, getting a pure beautiful, rich sound than have a long lasting flat string. My thick stock strings were killing my fingers. These are effortless to play and sound so sweet and mellow, just like an acoustic should sound.Again, someone will chime in and bash me for saying this…but I would put my inexpensive Yamaha up against guitars costing 10 times what I paid. I have no plans of changing brands now I’ve made the string switch. Some say thin strings break easily, but you should change strings often anyway. I can do a string change-over in about 15 minutes on a bad day. It’s worth the effort. I don’t plan on hammering my acoustic anyway. That’s what the Fender is for. AND it’s not that I’m cheap either. I own 18 guitars, 16 of which are electrics. 3 Gibson Les Paul’s, 2 Fender Strats (one American) a couple of Dillions (another great find) and some other nice guitars.My Acoustic is just an inexpensive Yamaha 700 but is a very nice guitar for the money. But after changing the strings it sounds like an expensive Martin. It didn’t take me long to throw a set of these on my acoustic electric and got the same results.5 stars in my book, more if they’d allow that. There are no other options unless someone gives me a set that blow me away.

    Great Strings for Beginners

    Installed on a Martin D-15M, had never changed strings in my life and it was easy. These lighter weight strings seem easier to fret and don’t buzz. Great for beginners like myself that haven’t developed the finger strength for thicker strings. If there is a compromise by using the Extra Light strings VS Medium I’m not sure what it would be. These sound great to me!!

    Good strings

    This is my favorite brand of strings. Strings this light for a 12-string guitar were a challenge to find.

  23. ARL

    Loud and clear

    I decided to replace my EJ26 coz for me i think it’s so thick and my concern for thin string is the poor clarity. This string still has warm and clear sound like EJ26. Very nice!

  24. Badonka_what!

    Love these strings

    Strings have always been great.

  25. El Jefe

    Easy to install & sound great

    Headline says it all, love the warm sound of these strings & the extra lights make barre chords less annoying lol while not sacrificing any strumming tone (to my ears).

  26. TerryH

    EJ-19s = Dull sounding on my Yamaha, but EJ-16s = Awesome

    I like a warm tone and love the ways my Yamaha FS830 sounds. I thought the EJ-19s would sound even warmer than the EJ-16s, but just sounded dull. Not sure if just not a right fit for my guitar or possibly the low E and A strings might have been to big to fit properly in the nut slots, or so it seemed when I took them off to put a set of EJ-16 back on. (Which sounded awesome again!)

    Great strings for a great price.

    About the strings for my seagull guitar. Makes a beautiful sound. Easy to string one string did break but that was because I was being a little bit rough. As long as you’re careful you should be fine. Quality brand nice set.

  35. Amazon Customer

    Good when fresh

    These are very good when they are new but they don’t last as long as I would like…If you like changing your strings more often they are good. They cost less than some so it’s a trade-off…

  36. CJS

    The best of the best.

    Look no further than these. They are timeless and will last long enough to make you want to change strings when the time comes(to a fresh set of EJ42’s). Every other brand (and I’ve played most of them) sound great but have either had an early breakage (I play Beard’s so its not the instrument) or lose tone so fast that string changes become more trouble than they’re worth for most players.

    D string broke while stringing guitar

    Absolutely love the tone, brightness of the strings. Easy to chord which makes it great for beginners and professionals alike. Only disappointment was the D string snapped while trying to string the guitar. I guess I will have to order another set just to get the D string. I will purchase these strings again.

  40. BuckBran

    Good for average players who don’t wanna pay a lot

    I’m certainly no professional or anything like that but I play guitar all the time. Because of that I run through strings fairly rapidly, so for the price these are a good option. Honestly, the reason I give 4 stars is because to me the sound fades pretty quickly, but they last well after they fade and because I’m just playing for fun, I just keep playing them despite the sound not being so great. So for the money and the initial sound quality they are perfect for me because all I really need is strings that can last a while and let me enjoy playing without emptying my wallet. Also I usually get the light(sometimes custom light), and not only have I never had a string break while stringing it like some other reviews have reported, but typically I don’t have a string break until well after it feels like one should. Also if I had to guess most people who complain of strings breaking either don’t know how to string a guitar or(and) are using extra light strings because I have with another brand had the extra light G strings pop while stringing which is one of the several reasons I don’t use extra light anymore. Those strings are just too tiny and too easy to break. I had to replace my saddle because I was breaking strings like crazy a while back. It was always my B string and finally I realized the saddle had a sharp pit in it that was cutting my strings. I was wanting to upgrade to bone anyway so it worked out and I haven’t had anymore issues with strings breaking before expected.

    Best acoustic strings I’ve ever used

    I’ve been playing guitar over 50 years and these have the best sound of them all.The bass really comes through with these strings. D’addario Bluegrass strings are my go-to strings from now on….BTW, I don’t play bluegrass.lolI don’t know how long they will last and don’t care as I will reorder as often as needed. Sound is everything and these strings have it all.

    easy to install, officiant packaging.

    As someone who’s never changed a string themselves before, I had 0 clue if I even bought the right kind of string in the first place, but it was surprisingly simple. It is a very pretty gold and comes with all 6 of the stings, and sounds great even next to my other strings that are not of the same brand. It’s pretty much everything you could ask of a guitar string. My only gripe would be the length. It had a decent bit extra to clip off but it still felt a little short but it didn’t cause any problems and I doupt it would for others. (for reference my string ended up being roughly 2ft 1in after applied)

    Best strings in my opinion and opinion of many musicians and store owners I know/knew in the past

    Prefer lighter D’Addario for playing out…a little brighter BUT for the guitars sitting around the house for constant play/practice/jamming with friends or whoever the mediums are just fine, last a little longerGenerally, ANY strings only last one set when playing out.
