D'Addario Pro-Arté Carbon Classical Strings EJ45FF, Normal Tension

I love these strings. Beautiful tone

They sound much brighter and significantly improver the dound of my old cheapo Yamaha guitar. They took a bit longer than traditional nylon strings to set in, but after they did, the tuning is stable. They just feel better and sharper and deeper toned than nylons from the same manufacturer. I am sure they will sound even better on a higher-end instrument. I did notice the wire wound on the 3 lower strings get worn relatively quickly (you see pressure marks. However thats not a big deal for me. I actually periodically sand my wire wound strings with high grit sand paper, and very soon they do not exhibit any finger noise anymore, plus you stop seeing fret pressure marks on them as the wire gets flatter - that without any noticeable deterioration of the sound, and quite the opposite, the sound gets richer.

These strings have the most wonderful sound when comoared to the next lowest priced D'Addario set. I will continue to purchase these strings.

You might need to use light sand paper to scuff the ends of the smaller strings, as no matter how I tied them they continued to slip. After some slight scuffing to increase the friction around the bridge and tuners, they held perfectly. I'm only slightly above average, so the best opinion on sound is that it's "good." The carbon series does deliver the best tone in my opinion, and for flamenco guitar I love normal tension, but of course that's all a matter of personal preference. Nevertheless, you won't be disappointed these, but if you don't have a sharp ear D'Addario's cheaper classical strings will provide you an almost identical experience.

I am a casual hobby player, not a classical guitarist. I have a Breedlove Discovery nylon string “crossover” guitar — not a true classical guitar — with a solid cedar top, that came with extra-hard tension D’addario nylon strings. For my taste, the stout strings sounded dull on the heavily braced cedar Breedlove. On a whim, I tried these carbon strings. Their sound is brighter and more resonant on my guitar. I went with NORMAL tension because the carbon strings’ total tension in Normal is 92 lbs (the same as extra-hard tension regular nylons). The total tension of the HARD carbons is 102 lbs. (The back of the package lists the total tension.) My guitar is heavily braced and could probably withstand 102 lbs of tension, but why chance it. Carbon strings are a bit stiffer than nylon, so NORMAL tension allows my strings to vibrate freely. Of note, the G string in this pack seemed SHORT and was an absolute bear to attach to the headstock after it was secured to the bridge with two loops. I hope that was just a QC thing, because I would not want that struggle again!

My go to strings

Installed these about a week ago on my classical guitar. Guitar is keep at constant 45% humidity. Have bought and used many other D'Addariostrings on my acoustic and electric guitard. However these strings have been impossible to keep in tune, but I figured thats normal for nylons in first few days. The sound is kind a deep dark character with dull finish. I was hoping for more brilliant quality. This morning I came downstairs to see the G and high E strings had snapped overnight. $19 in the trash. 😡 Will not be buying these again.

Recently bought a Cordoba c3 because of the solid cedar top and low price. The strings the guitar came with are ok but sounded plastic-y in the higher ranges and a little on the thick side with the dreaded muffled g string pronounced Imo. So i ordered D'addario ej45 normal tension and the feel and sound was good but again was too muffled and i was starting to think it was the Guitar and filed for a return. Just as a long shot i ordered these D'Addario EJ45FF ProArte Carbon Classical Guitar Strings, Dynacore Basses, Normal Tension and i'm in heaven, even the g string i have to keep looking at it as i play because the sound is so good i think i'm on the b or d. this guitar sings now and the return has been canceled. (For those who have trouble with the e string being too slippery and coming undone) when you tie off the small e string go through the bridge hole twice and then go around the e string , finish with the double over under pinching the last bit of string behind the bridge block and tighten no slipping that way.

Nach Thomasik (davor Hannabach, Augustin) Nylon-Saiten, die mir etwas zu leise und weich waren, hab ich jetzt diese Carbon-Saiten aufgezogen. Auf der Elektroakustik Yamaha CGX 171CCA klingen sie wirklich super. Die Gitarre singt. Sogar die G-Saite ist nicht dumpf. Sie reagieren sehr dynamisch auf verschiedene Anschlagstärke. Die Bässe sind kräftig und auch nicht dumpf. Angeblich sind sie Normal-Tension, was aber zumindest subjektiv gar nicht stimmt. Die Saiten haben eine sehr hohe Spannung. Vibrato ist vor allem auf den Bass Saiten kaum realisierbar. Glissando ist sehr laut. Ich bin mir nicht sicher, ob ich diese Saiten auch auf eine zarte teure Konzertgitarre spannen würde, aber für mein Modell sind es bislang die mit Abstand besten Saiten. Sind hier auch bundrein. Bin begeistert vor allem von der G-Saite. Edit: Am 2. Tag, beim Üben von Läufen, also eher mäßige Beanspruchung, ist die Hohe E-Saite mittendrin (nicht am Sattel oder am Steg) gerissen. Vermutlich ein Fabrikations-Fehler.

Tuned the strings to standard tuning, but the treble strings wouldn't stay in tune. About a week later I woke up to find the strings had snapped overnight and had left a gash on my guitar's top where the strings hit the top. I regret trying these. They damaged my instrument, and were a waste of money. I've never had the treble strings snap on me before in maybe over 17 years of using D'Addario nylon strings. I cannot recommend these carbon strings. On the sound, they are brighter than the regular nylon strings I've used before. If you prefer a rounder, mellower classical sound, these won't do. If you like the brighter sound, closer to a steel string acoustic, then maybe these will work if they don't snap like mine did. They look thinner than regular nylons, and they appear to have higher tension (I bought normal tension ones), which is perhaps why they broke. Perhaps because of the higher tension, they also feel a bit louder and punchier, but not as deep.

I bought this in September (2022) but only got to string one of my classical guitars with it last Sunday (201122), looking forward to a beautiful rich sound. When I opened the packet, I noticed that the G string had a flaw in; kind of like little fray. I decided to go ahead anyway. Immediately after stringing the guitar, the sound was indeed beautiful; warm harmonics. However, the very next morning, after retuning, I discovered that all the treble strings were completely flat - dead - no harmonics whatsoever. A snare drum has a great deal more than those strings. A few minutes later… twang! The B string of all strings snaps. I restrung the guitar with Hannabachs and now my 1970 Yairi Gakki sounds beautiful again. Please note, this is not a dis of all Daddario strings. I like them and use them all the time, but this particular Carbon set is definitely a dud. Fortunately Amazon immediately reimbursed me following the return of the dud set. I would definitely NOT recommend this carbon set to my worst enemy.

Very clear, bright tone and excellent projection. The carbon trebles feel smooth and responsive, and the tension is comfortable for long practice sessions. Easy to tune and stay in tune well. Fantastic upgrade for classical guitar players – highly recommended

É uma corda muito boa. Tem um som maravilhoso. De todas as que espremerei esta foi a melhor. Vou usá-la por muito tempo
