Bst ever!!
May 23, 2021
These r the best ever! Once they stretch out, they really stay in tune and r the best sounding strings I ever tried (even better than the Savarez 500's) The trebles really sing out - my guitar sounds like a VERY expensive guitar with these strings! (I have a Kremona Fiesta F65-CW) ($1100) made in Bulgaria - beautiful sounding even without the Aquila strings but these strings really make it sound beautiful! I think I will no longer be trying other strings!

Greatly improved the sound and feel of a pretty good guitar
April 10, 2021
Bought a used popular low-end classical cutaway to have something on which to practice Samba and Bossa Nova. The strings on it were gratingly bad and not responsive. I dressed the frets, put the Alabastros on, and the guitar immediately had more of a voice, greater response, and dynamic range, and even a little bit of presence, so it is much more fun to play!

I am done with heavy gauge
April 27, 2019
I have used offerings from D'Addario, Luthier, Savarez and Aquila. I was introduced to Nylgut on a ukulele, which produces a clear, chimey rounded treble. Initially I bought the heavy gauge - "Superior" - Alabastro set which performed well on my Alhambra 8P. I have seen occasional comments about using lighter gauge strings, and have discussed the topic with a local luthier who no longer uses heavy strings on his hand-built guitars. After trying these - Aquila's "Normal" tension - I am sold and won't be returning to heavy gauge strings. Nylgut has a nice feel - a bit of texture - and is a little different than other nylon strings which feel to me like fishing line. The basses are clear and lack the noise produced by other brands. Initial break-in was very fast. The lower tension has been very kind to my left hand, and has improved my technique. Slurs up and down are much clearer and cleaner. The slightly smaller gauge (only about .003 smaller than the heavy set by my measurement) feels right under my fingers. High B at the 19th fret does not choke. A small adjustment in my right hand technique - playing a bit lighter - was the only consideration. Overall volume is only slightly less, but I have been rewarded with air on the tone, greater clarity and better stamina when playing. Recommended for any serious player.
ProsFast break-in. Dense tone on the trebles. Little noise on the basses. Easy on the left hand!
ConsVery slightly reduced volume.

Alabastro Mediums
June 11, 2011
I have used the higher tensions offered by Aquila before but this is the first time trying the mediums. None of the other reviewers seem to have long break in times or at least if they do it is not mentioned. I noticed this with the high tensions on two different guitars. The mediums took nearly four weeks of daily (~1 hr/day) playing to settle enough to produce a clear harmonic at either VII or XII, During that same period there was a noticeable deadness of the 4th string in the seventh position. Aquila suggests pulling on the strings to speed break in and perhaps I did not pull enough by hand but long break in is something to consider.

Now that the strings are pretty stable intonation is quite good, harmonics sing and when used in a drop D bass tuning they just seem to come alive.

Also the bass windings are of a fairly soft alloy of what appears to be a somewhat smaller diameter wire than most other strings. This means very quiet transitions and slides.

In use, I think these sound very good with lute transcriptions and period pieces as a solo instrument. Not sure how they would stand up in a chamber situation especially with quintet.

full set alabastro

The tonality of the strings is impressive to me. I have not owned a classical long, but it's a cedar top w/ rosewood back and sides (all solid wood). the previous strings were d'addario pro'arte mediums and these had a much fuller sound compared to those, especially when played fortissimo. I would not recommend the basses particularly because the packing is quite minimal and not even sealed. the basses came to me with corrosion on all strings in at least 2 or 3 places.

Great strings
March 24, 2011
I've used Aquila's on all my ukes and was very pleased to try these on my classical guitar. They bring out the sound of the guitar in the same way the ukulele strings do the uke. They are brilliant. Feel great, and sound wonderful.

I am very pleased with the sound these strings have given my guitar (Pavan TP-30. Spruce soundboard). The basses were always nice but the trebles have just come alive.

Wonderful tone and stability that endures heavy use show after show. Follow proper installation procedures and stretching time for best results. I use Aquila Nylgut strings exclusively on my ukuleles and classical guitars.

Aquila Alabastro Strings
December 13, 2009
These are by far the best classical guitar strings I have ever found. The only ones better are the Alabastro heavy set, or superior tension. I find the Alchemia set to be of the same quality sound, but not worth the price difference for silver wound insted of silver plated. I highly recommend Aquila Alabastro strings, in both medium and heavy.

Nylgut is a completely different material than Nylon and needs a bit of extra care during installation because of its soft surface and different molecular structure.

First check that the string channels in the nut are rounded and have no sharp edges, especially the lower edges facing the fingerboard. Because the string approaches from a slightly downward angle, if that edge is sharp the string can hang up on it, create a burr and break. It needs to be just slightly radiused, and this procedure can be done with very fine sand paper and an old string, or a small round file. Some makers ignore this because Nylon strings are very hard and can withstand a poor set up. Sometimes bridge saddle edges on the tying side are sharp as well and should be radiused slightly with fine sandpaper.

It is good to help the strings over the nut by lifting them slightly right at the nut as you tune up. Plain Nylgut trebles stretch like crazy so you should also cinch the strings up tight on the barrels before winding. Be sure not to overlap wound strings on the tuning barrels. The preferred method is to put a set on an instrument in the evening, bring them just up to pitch, let them sit overnight, and finish tuning in the morning. This allows the molecules some time to adjust to being stretched. Give them a week or so to stretch in fully (less for ukulele strings) before passing any judgment on tone as it takes a while for them to develop their best sound.

Set with two degrees of tension. The first three strings use monofilaments of rounded, polished Nylgut® "synthetic gut". Its features include promptness of attack, acoustic projection, excellent timbre and a truly remarkable stability of intonation, not to mention an admirable evenness of tone with the overspun basses.

The basses, overspun with silver-plated copper, consist of a core of Nylgut® multifilament that ensures not only a high resistance to tensile stress but also a low absorption of both atmospheric humidity and sweat. This makes for rapid and stable intonation, as well as greater durability.
