Very different strings. Players either fall in love with them and don't want to play anything else, or they don't care for them and can't bear the price tag. They are expensive, but may be worth it. because if you like them there is nothing else like them on the market. I think these are made primarily for a nylon string guitar; they make a nylon string sound a "little" more like a steel string guitar. Stands to reason since they have very fine steel rope strands as the core. That said, it is still a much softer and mellower tone than any set of phosphor bronze or 80/20 strings. The strings are very low tension, I think about 90lbs total across the set, which is more like a set of medium-to-hard tension nylon strings; that compared to 130-160lbs and more from conventional steel string sets. So you should never put steel strings on a classical nylon string guitar, it will damage the top, may even rip the saddle off the top. Nylon string guitars are braced lighter and have thinner more delicate tops because they don't have as much string tension. But you can safely put these on the most delicate classical nylon string guitar -- that is the real intent of Thomastik-Infeld with these strings.Vice versa, the opposite is also true: nylon strings do not work on a standard acoustic guitar that is meant to have the tension of steel strings to move the top, however I have used these on my steel string acoustic guitars. It may require a little neck adjustment and though they may not have as much volume, they do work and give a nice mellow tone. What is surprising with the soft feel of the strings is that they have such good sustain and a wonderful low end from the bass strings. The tension from string to string is very balanced and they are a pleasure to play once you get used to the slack feeling of the strings. It feels a little like if you take a steel string acoustic and tune it down a full step or more. If you don't like that loose feeling, you won't like these strings. If you do, you will love them, because you'll get that loose feeling with your guitar up at concert pitch.These strings are good for older guitars that you would prefer not string up to the full tension of conventional steel strings, because you're afraid of damage. More than the sound of these strings, for a standard acoustic steel string guitar, you'll like how comfortable they are on the hands and fingers. If you have arthritis or any condition that has made playing acoustic guitar really rough on your hands, these strings may be just the ticket to keep you playing. Keep in mind they are going to feel loose and will have to learn to fret with a much lighter touch. To me, it's exactly like when a player of steel strings picks up a nylon string guitar for the first time.They are beautifully made strings, very unique, and as with many of the offerings from Thomastik-Infeld you may think, "I love these strings, I wish they weren't so damn expensive, but I love these strings."

I really like these strings. These strings are very smooth and make no squeaking noise when playing the guitar. They feel like silk and are very easy on the fingers. The sound is bright and clear and crisp with wonderful bass tones coming from the lower end strings. Excellent quality. I highly recommend these strings.

Calidad y buen sonido
