Great sounding strings, especially for drop d or open d major tunings.

In short, outstanding strings. Like any other string, they too need to be changed. However, my guitar(Sand-RS model) sounds better with them on than the regular extra hard tension with the nylon core. I recommend them.
D'Addario EJ44C
September 24, 2014
I just completed an extensive classical guitar string review with my family and friends. I used D'Addario EJ44Cs, Savarez 520PIs, and Thomastik-Infeld KR116s. I combined each brand of string into the basses and the trebles. I repeated the sound tests three times for the basses by rotating which string I used by brand. I repeated the test seven times for the trebles because the D'Addario set came with both a nylon and a carbon treble (I realise that I would need twenty four tests to truly test the D'Addario trebles, but as a trophy husband I only have so much time and patience available for this). No one chose a Thomastik-Infeld KR116 as their favourite bass or treble. The Savarez 520PIs were the favorite overall, however, the D'Addario EJ44C basses were selected more often than the Savarez 520PI basses.

In conclusion, in my test the D'Addario EJ44C basses and the Savarez 520PI trebles were the favorites. I just completed an order for D'Addario sets and separate Savarez 520PI trebles; I will not use the D'Addario trebles. I ordered the three plastic-wound types of g string available from Savarez. I will repeat my testing with those three when I receive them, although without head-to-head testing it will be more subjective.

In your own testing, remember that your guitar sounds different to a listener in front of the guitar than it sounds to you when playing.

These strings are my absolute favorite for my Nylon string beauties. I have tried about every Brand, strength and price of nylon strings available. IMHO you can not buy a better set of strings at any price for dependability, projection, articulation or warmth no matter what style or styles of music you play!

In the 20 years I have used D'Addario strings I have only had two individual strings that weren't absolutely pitch perfect, and those two were usable. The tone is fantastic, and these composites are very long lasting.

D'Addario Composite classical super high tension

Among the very best strings I've used. I play many hours a day professionally and they sound good and last a long while.

They do eventually lose their "punch" but they never fray or break.

Highly recommended.

"Pro·Arté classic guitar strings are just that -- classics. The treble strings are made from a harder formulation of nylon, and are precision extruded to guarantee a string that's even in diameter from one end to the other. And as an added quality-control measure, every single Pro·Arté treble string is hand-fed through a laser micrometer and sorting station to ensure that the string in your package tunes to the exact playing tension you're looking for.

Nylon is extruded in molten form; this process yields material that can vary in diameter by plus or minimum one thousandth of an inch. Though this difference is only about one fourth the thickness of a human hair, professionally trained classical guitarists can sense the contrast in string tension when the diameter varies by small amounts. The solution to the problem presented by this tension variable was to apply the latest technological advancements to the building of a sorting station, which utilizes a laser micrometer and a high-speed computer. The laser takes nearly 200 measurements on each string, compares and averages the data, and drops the measured string into the proper tension bin.

What's the end result? Every time you purchase your favorite tension of Pro·Arté  classics, you get the same exact string diameter to within four ten-thousandths of an inch.

The wound strings in the Pro·Arté line are wound with silver-plated copper or 80/20 bronze wires on D'Addario's own computer-controlled automatic winding machinery and are available in 4 different tensions for classic guitar.
