Thomastik-Infeld CF127 Classic N Superlona NT Guitar Strings, Full Set

Really great feel. Rich. Resonant with A+ sustain.

These are very strong, clear sounding strings with a serious sound; however, on my guitar, the trebles aren't quite as strong as the bass strings. The trebles get drowned out by the bass strings very easily. The trebles also don't bring out as much color as I'd like; of course, this is all in the context of my guitar. These could be great on other guitars perhaps, but overall excellent strings!

Thanks for sending this Thomastik guitar strings.
I'm really enjoying them.
Excellent sound. Not so brilliant, but strong.
These strings are the most perfect to play "Asturias" and other Latinamerican works.

Excellent in my guitar.

I purchased these strings for my Yamaha SLG200n hoping they would solve a few of the issues I was having, and they have FAR exceeded my expectations!!

The basses sound rich and deep. A strong fundamental with beautiful, subtle overtones. The trebles sound sweet and clear with a great balance between all 6 strings. The difference in tone and feel between the wound and plain nylon strings is almost unnoticeable now!
They also almost completely eliminated the annoying "buzzy" quality regular roundwounds have with piezo pickups, as well as the slightly boomy/muddy sound I was getting on the low E and A strings before.

With regular roundwounds the tone of the Yamaha was a bit on the sterile/dead side of things. Now she sings with a lively richness I never imagined I'd get! Really incredible.

Now, the best part of these strings: THE FEEL!!! If there's one thing Thomastik does well, its flatwounds.
The basses are buttery smooth under the fingers and allow me to get a nice, low action. A real pleasure to play! (they also have the added bonus of completely eliminating the borderline obnoxious string noise I was getting with regular roundwounds on the SLG.)

I'd imagine results will be similar on any electric/electro-acoustic, piezo driven, nylon strung guitar. Really a perfect match for these kinds of guitars.
As for traditional acoustic instruments, I can see these being lovely too on the right guitar. I plan to try them on my acoustic next.

Overall These were well worth the money, and I'd imagine if they're anything like their steel string counterparts, they'll last significantly longer than roundwounds as well!
