Daddario NYS013 Single String

s a player of a guitar-like instrument with unique specifications, I needed to create my own string sets, and I chose to build mine entirely from D'Addario NYXL strings. Initially, the sound was a bit too metallic for my taste-bright and sharp, almost edgy. However, after some playing time, the tone mellowed nicely, becoming smoother without losing that essential brightness. It never turned dull, which is a rare and welcome balance.

Tuning stability has been excellent; I haven’t experienced any tuning issues despite daily use. Additionally, after a month of consistent playing, there are no signs of corrosion or wear, which speaks volumes about the durability and quality of these strings.

Overall, for anyone customizing string sets or experimenting with different instruments, the NYXLs offer a fantastic combination of bright, clear tone, durability, and tuning reliability. I especially appreciate that D'Addario offers unusual string gauges, like the 0.019 gauge, which makes it much easier to find exactly what I need for my custom setup. For me, that’s a definite win!

When testing this set of strings I discovered the following:
1) Very nice tone !
2) More output compared to other nickel-wound strings of same gauge
3) More stretch for extreme bends
4) Keeps retention better over time compared to other strings
5) Easy to play and nice feel
6) Improved tuning stability
7) A pretty long-lasting "new-string-sound"
8) Keeps that "I just changed my strings feel" much longer than regular strings
My conclusion: Going forward the NYXL series will be my favorite set of strings for most of my electric guitars.
Yes, they are considerably more expensive than the standard D'Addario EXL series or similar brands, so it's up to the customer to decide whether those differences or improvements are worth it.
Bought the single as it is nice to have the option of a spare strings!
