D'Addario Guitar Strings - Pro-Arte Classical Guitar Strings - EJ44C - Nylon Guitar Strings - Silver Plated Wrap, Composite Core, Clear Nylon Trebles - Extra-Hard Tension

I have a Breedlove nylon string acoustic. Not a classical but a hybrid. It was a little thin on the lows and a bit too bright in the treble. These strings do exactly what they say. Elevated, commanding lows and smooth mellow highs. Much better projection and string balance. I like the added string tension. Great strings!

Just changed my dad's fine Classical strings which were muddy and lifeless after only a month...These have totally transformed the sound of this very expensive instrument...Excellent purchase...

These are decent strings with good projection. The composite G is quite good. Tuning stability overall is subpar though, as I have to retune after every song, so I think I will switch to a different set.

I've used the D'Addario Composites on and off since they debuted in the early 1990s. There are more strings choices on the market than back in the day but I always come back to the Composites. The tone is a traditional mellow timbre, similar to Dynacore and the standard EJ44, but with a brighter sounding G. The problem with nylon 3rd strings is they tend to be too mellow—even dull and tubby—and this tan colored monofilament has more bite. So better for lyric solos up and down the 3rd (G) string and a smoother transition between bass and treble timbre. A nice thing about the monofilament 3rd string is it almost lasts forever. The other trebles will be scratched and worn, losing tone and sustain after a couple weeks of hard playing but I can leave the 3rd string on through many changes of basses and trebles.Be careful when winding up to pitch as both the bass and monofilament 3rd string require about 75% fewer turns to hit pitch than standard nylons. If you simply turn the tuning key the amount of turns standard strings need, you'll be an octave high and break a string. Finally, the both the bass and monofilament 3rd string stretch out quickly, holding their pitch much sooner than regular nylon strings. The two upper trebles are just standard nylon so they stretch forever.

I’m using these on a crossover guitar as I’m mostly a fingerstyle steel string player. I previously tried medium and hard tension conventional nylon strings. I much prefer these extra hard composite strings. I especially like the composite G string—it really helps the transition from wound to unwound strings. The tone and intonation are improved. I don’t find extra hard tension more difficult to play, but I’m used to 012 steel strings. The extra tension may allow me to lower the action a bit without buzzing. Or I might leave the action where it is and tune down a whole step—which could be nice for playing solo.

I put these on a $81 Harley Benton classical acoustic. These pro arte strings are far superior to the stock strings. I really dig the composite G string. I play self taught fingers style guitar with no nails, I can still make these sing loudly and sweetly. It did take too long for them to stretch, sounds amazing.

Popped a string, opened the new pack of strings, and I see a short coiled piece of cooper???? Also, a duplicate high E string. Grabbed a second package, the D string snapped before it reached proper tuning. Reconsidering buying somewhere else. Knock off? These are typically solid strings.

This review focuses on the fourth composite string.The fourth string has the unfortunate problem of increasing slightly in frequency (roughly 0.5hz) with larger amplitude, or in other words, the pitch changes extremely slightly with higher volume. When you try to tune the string, this is particularly annoying. You can tune easily the other five strings, but that composite g-string is very difficult to tune. You pluck it, and you can hear the frequency trying to settle for about a second. I need strings to have good pitch vs volume stability. This new composite material is not up to the task, I believe.If you play without any vibrato frequently, and you need the strings to be in strict harmony, it is frustrating. In the future, I would stick to 3clear/3wound strings, or 2/4.
