Review: Excellent strings! - Just as a background, I'm an amateur guitarist, I've only played for about a year, but before that I played piano for a few years when I was 8 or so, and played violin for 6 years, up through 7th grade. (I'm 18 and a graduate now). So while I may not be the go-to guy, for guitar, I have a fairly musical background. I originally bought these strings, just because they were one of the cheapest set I could find on desertcart that were made by a reputable company. I've mainly only used D'addario strings up to this point, but decided to try a different brand on a whim. My main concern with these was the string composition. I had only used Phosphor-bronze strings because I really enjoy a mellow tone. What I had heard of string composition was basically there are: 1) silk-wound strings: which play like classical and are really soft but wear out very fast 2) phosphor bronze: generally heralded as the go-to string for guitarists. Nice mellow sound 3) 80/20 mix (these): with a "brighter" sound Because I have always enjoyed a sweet sounding, mellow tone (like piano) vs a brighter tone, think more like harpsichord, or violin, I was steered away from these strings. But what I found was that these strings teased some of the most beautiful sounds from my cheap, starter guitar. The "bright" element isn't really so much the sharp unpleasant sound I had assumed, but more like a chime on top of the normal range of sounds. After 3 days or so, the sound mellowed out even more, and I think the end result is even smoother than D'addario Phosphor-Bronze. If you play any music with artificial harmonics (think Tommy Emmanuel), my God, these strings sing. The harmonics come out bell-like and have incredible sustain. Also, these strings produce a lot of volume. I switched from D'addario mediums, to Martin lights, and I didn't notice a volume drop. Granted those strings were old, but I think I had only put about a month on them, which is probably the shortest I've gone between string changes. I'm pretty sure these beat out the more expensive D'addario EJ-16 (phosphor bronze, lights) in the volume and clarity category. It might not be fair to compare different string compositions, apples to oranges, but out of the strings I've tried , I like the sound of these best. Finally, perhaps most importantly: playability. These strings are the "softest" metal strings I've played. They're gentle on the finger, and I feel like there is less tension than D'addario. These take a pretty minimal amount of pressure to fret without buzzing. I play mostly fingerstyle, so this is extremely important. So bottom line, these strings have fantastic tone and clarity. If you're a fingerstyle guitarist, then I would definitely get these. I'm still trying out new strings for my guitar, but up to this point, these are my favorites. If you don't want to switch from phosphor bronze to 80/20s in fear of losing that mellow sound, don't be! These strings sound just as mellow after a few days of breaking in. Love these strings! Will buy again.

### ⭐⭐⭐⭐⭐ Clean Old School

Old school sound. The strings I’ve been looking for. Highly recommend! Clean sound

### ⭐⭐⭐⭐ Good strings in a pinch!
*by K***R on March 5, 2012*

Easy to restring using these strings. These replaced my classical/nylon strings and I was pleased that I did not have to spend the time to loop them at the bottom. However, they are a different animal than the nylon strings they replaced. Lucky for me I did purchased them just in time because one of my strings broke and I was forced to be bothered with the task of replacing the strings but that went surprisingly easy. Sounds way tonier (almost like a harpsichord) than the old strings and my fingertips have to get used to the change, but the new strings have an incredible resonance that the old strings lacked. Could not beat the price or the convenience. Plan to order another set soon although might try an upgraded set. Still, a good buy and convenient.
