They feel and sound very different from typical classical guitar strings, but their intonation is perfect, they quickly come up to pitch and stay there, and harmonics jump off of these strings.
They almost sound a bit like steel-string acoustic strings (of couse, they should given their construction), but they are not overly bright. They also last an incredibly long time (like all of the Thomastik-Infeld strings I have used), and they are, at least to me, well worth the expense.
With a seven-octave stroboscopic tuner try precise Pythagorean tuning. Everything is ready for a clear six string chord. Open strings, ethnic music, even dissonance is more interesting. Get above the 12th fret and find the range of tiny volume control.
But do be careful putting them on. They are very easy to mount - but if you bend the silverplated copper string it will remember.
Wow! is my review. At least for this guitar.
They are bright and full and feel great. The basses are thinner than standard nylon, so your set-up might need a touch up. The ball ends are not strictly nylon. But I think they are required because stringing them the classic way may lead to early breakage at the saddle.
Haven't tried them on a standard classical acoustic yet.
These are the worst classical guitar strings I have ever encountered.
1) They don't fit on the instrument. The low E-string is so thick it only fits through the standard hole size with great effort
2) The strings have a metal cylinder on the bridge end which are not used on classical guitars. This mechanism is for acoustic guitars only.
3) Once on the guitar there are several evident problems. For one they are out of tune by .1 to .25 cents!!
4) I'm not recalling the term for this but due to their un-eveness they actually don't have a consistent pitch the pitch wanders
5) Talking about tone quality is irrelevant at this point these string are unusable.
I called justforstrings and asked about their satisfaction guarantee policy: "You can't just return them if you don't 'like' them. If you think they are defective call the manufacturer."
The one caveat I have not seen here is that you may need to have a new nut cut. Although the bridge was fine, I got a lot of string buzz on the open string until I replaced the nut.
What a night! After that, can I put anything other than Thomastik-Infeld metal strings on my Ventura Bruno? Never.
I have a Cordoba C7 and these strings make it sound beautiful it has a great electrical sound plug it in the amp.I'm very happy with my guitar now. Thank you Juststrings.
The first thing you notice is the high tech flat windings in nylon and in silvered copper. Like 3D chains. Then you find they tune up and stay in tune right away. Amazing. The sustain is incredible, the volume is all you want, there is no break in timbre between the basses and trebles, yet the top strings sound much like a velvety nylon or PVF, and the basses ring rich and harmonic. It's true to the ideal sound of a Spanish guitar, that nobody else quite reaches. It's hard to grasp how they do it. With a little EQ, you can bring out a huge range of tones, because there is so much there. The tension is perfectly balanced, and neither too light nor too heavy. These are not wimpy super low tension strings, they are both sensitive enough for fingertips and rigid enough for nails. They ooze such aesthetic and technical perfection that I spend time just staring at them. Absolutely the best strings I have ever played on a Spanish guitar. Well worth every penny, so much so that I'm willing to buy two sets to try on an (11 string) oud.
