Carbon vs. Nylon Classical Guitar String Comparison. (D'Addario EJ46 vs EJ46FF)

Amateur-style comparisons of D'Addario EJ46 nylon core and EJ46FF carbon strings on my Cordoba C7 guitar. I also added samples of the 6-week-old strings (EJ46) that were previously on my guitar for reference. Here are some of my observations:

The EJ46FF strings include carbon trebles and Dynacore basses. The EJ46 strings have nylon core basses and nylon trebles.

I tested each set two days after stringing the guitar.

The packaging states that the EJ46's are "warm, full-bodied tone and consistent intonation." The packaging of the EJ46FF's says "vibrant modern tone" with "bold powerful sound, responsive feel, & improved intonation."

I would agree with both of these assessments! I found the carbon strings to be quite loud and lively with lots of sustain. My first impression was that they almost reminded me of steel strings. They have a higher tension, and the treble strings are thinner than the nylon trebles. When strumming these strings, the fret-buzz sounds more pronounced...almost metallic.

The nylon strings have more of a rounded and warmer tone. They settle-in quickly and last a long time. I thought the 6-week old set sounded good when I took them off to do this comparison.

The thinner carbon trebles take a little getting used to, and my first impression is that the high E string feels too thin and high tension. They are fun to play, however, as the sustain gives almost an electric vibe.

I would like to try the Dynacore bass strings with the nylon trebles.
