D'Addario EJ45FF strings

A few months ago when stocking up on strings (I'm sorry Local Music Shop, but I buy my strings online, because I always get exactly what I want and it is half the price even with delivery) I noticed my normal string of choice - D'Addario EJ45 - now come in a "Carbon" version. I finally wound them on and observed a few points:
  • The trebles are transparent. For some reason I thought they be non-transparent!
  • The trebles are thinner. In fact the 3rd string is about the same thickness as a normal 2nd string. But then on the basses, the 4th string is a tiny bit thinner, the 6th string is a tiny bit thicker, neither enough to notice, the 5th string remains the same:
String     | Nylon  | Carbon
1st string | 0.71mm | 0.61mm
2nd string | 0.82mm | 0.69mm
3rd string | 1.02mm | 0.84mm
4th string | 0.74mm | 0.71mm
5th string | 0.89mm | 0.89mm
6th string | 1.09mm | 1.12mm
  • The thinner trebles are noticeable, but did not cause me any issues.
  • The trebles a brighter tone than nylon. Note the "carbon" in carbon strings means that the filament is made from fluorocarbon, which is essentially a hydrocarbon where all the hydrogens have been replaced with Fluorine. The Carbon-Fluorine bond is apparently the second strongest bond known next to Silicone-Fluorine. Interesting. Nylon on the other hand is a synthetic long-chain polymer which makes more sense as a fibre, but we've just run out of my chemistry knowledge.
  • The basses are about the same tone as the standard EJ45's. Maybe slightly brighter, hard to say, you'd have to do a control test.
  • The trebles feel "silkier", maybe "slipperier" might even be a better way to describe them. The basses have the same touch and feel as nylon wound, I didn't detect any difference.
  • The trebles bedded in faster than nylon, as in, they stopped stretching and held their tune[1] in less time. The basses maybe the same too, I find the nylon wound basses bed in reasonably quickly anyway. Note that I have been re-stringing the same way for a while - basses one twist at the bridge, 2nd/3rd treble two twists, 1st treble three twists. At the tuner I pull the string tight and loop it over itself so a minimum amount of turns to reach tune. This has always been the best way to get a fast bed-in for me.
  • The tone lasted long enough, not double the time considering the double the price.
I played a few long gigs on this set of strings which deadened them quicker than if they were just in a practise rotation.  So the dynacore basses have a slightly better tone than the standard basses, and the tone hangs in there a little bit longer.  The carbon trebles have a nice bright tone that lasts but over time I found I disliked the thinner strings.  Will I use them again?  No, but in the future I will try the "dynacore" and the EXP coated sets. There's a web page showing all the D'Addario string variants here
[1] No classical guitar ever holds its tune. Just you holding the guitar for a few minutes is enough to put a bit of body heat into it which changes the tuning...which you re-tune compensate...and then when done pack away...and then next time it is out of tune again because it is cold again...



  1. Been a while. I'll a;ways keep coming back though. Circumstances beyond my control (nothing sad) have prevented me from playing guitar or piano for months now... listening to your teen spirit and shine as i write this. beautiful stuff! Never quit Mr. Robot!

  2. Good to hear from you RG! Don't stay away from your music too long if possible! Funny, just uploaded Teen Spirit, got "dressed up" for it too, ha ha :-) Would have recorded a few more songs ready to go but had places to be. Life is busy, but there is always time for at least a little bit of guitar.
