New!   Aquila SUPERNYLGUT®


supernylgut bulk


January 2014:  We are proud to launch the upgraded, ultimate  version of our famous white Nylgut® strings.

The SUPERNYLGUT® ukulele string have a charming natural pearl color instead the old milky white one and a very very smooth and polished surface feels like wax.  They are also pretty pliable but less stretchy than any previous Nylgut® version , this resulting in a faster setting to proper tune when new and in a tendency of easily maintaining the intonation when reached.

This help to do the tuning operation faster  dropping the general  production  costs

On top of this, Supernylgut is stronger and does not suffer from eventually sharp edges of the nuts, marks from frets or hard nail playing. And you can get all these upgrades together with the wonderful richness of tone which made our Nylgut® a success. Suitable for Ukulele & Guitar

                                                                                               SUPERNYLGUT® strings will replace, step-by step- the  traditional  white Aquila strings



New Nylgut logo

The New Nylgut® is the first product developed and patented by Aquila.

The New Nylgut® is nor common Nylon or Carbon (Fluocarbon fishing line or PVDF), or a mix of them. It is a plastic compound of three different components

Compared to Nylon, the New Nylgut® produces a better sound and stays in tune better, this because the moisture absorption is less of .1% against the 2.0% of Nylon normally employed for the musical strings (i.e. Du Pont Tynex® polyammide 6-12).

Due to the higher density, similar to that of pure gut (1.30 gr/cm3), the New Nylgut® produces a better sound than Nylon and it is not so metallic like those of the so- called ‘Carbon’ (Fluorocarbon) PVDF strings.

In other words, the New Nylgut® is probably the first genuine syntetic gut in the world.

The New Nylgut® assures:

1) a better sound than Nylon or PVDF, similar to the genuine gut strings

2) a more accurated fret-intonation due to the well gauged material

3) a very stable intonation under moisture changes

Colour: white

Bio Nylon logo

Bionylon® is a musical polyamide developed recently by us and extruded at our headquarter.

It is  a  100%  a natural plant’s derivate (castor oil). This assure less of 50%  carbon dioxide emission during the production.

The moisture absorption is very low, comparable to those of PA 6-12 (the common classical guitar’s Nylon). The performances are excellents.

Ukulele strings: vegetal green colour

Guitar strings: natural pearl colour.

Bionylon® strings are the first eco-friendly musical strings in the world!

Aquila RED SERIES® strings (the first alternative to the metal wound  strings)

cartellino pendente RED-SERIES scelta def


Who never dreamed of tuning the ukulele in low G, without  expensive and  fast rusty metal  wound strings?

Wound strings shows problems that on  ukulele are very considered:

  • shorter lifetime than the treble strings
  • sound power too bright and intrusive compared to the plastic treble strings
  • excessive sustain
  • noise caused by the fingers of the left hand
  • rapid oxidation of the metal wire during the storage & after a certain time

We are happy to announce that  the unwound fourth strings now finally exist. From now, you will finally be able to install ukulele in Low G ensuring sound power,sound quality and intonation on frets fully integrated with that of the upper treble strings.

Granted: no oxidation of the metal wire in case of acid sweat!

  • Color: red-brown
  • Surface: slightly rough; this texture has eliminated the squeak that sometime hapen with the Nylguts.
  • Elasticity/Elongation: like Nylgut & Supernylgut strings
  • Performances:  They do not breacks under stretching. fast and stable tuning
  • Intonation: accurate past the 12th fret
  • Pressing strongly the string on the frets, the note does not became sharper
  • It is not necessary to file the nut slot wider to accommodate it like hapen with the fluocarbon G strings

Silkgut logo

We can define Silkgut® like a cousin of the New Nylgut®.

The difference between New Nylgut® and Silkgut® is that the Silkgut® is a bit stiffer than New Nylgut®.

In other therms it last longer under the finger nails of guitar- players.

Silkgut® is suitable for classical guitar Trebles and modern Harp’s strings.

Colour: silked.

…ok, your loaded long gut string is the best from long time.So am am waiting until you can…
Kreg Viesselman – Norway
My luthier, Leonardo Michelin-Salomon of LMS guitars, gave me a set of your strings to try on the guitar he made for me. Simply put, I love them.
Thank you for your wonderful customer service, I cannot speak highly enough of your fantastic follow up and I will continue to use Aquila strings and a lot of that has to do with the treatment I have received from you and your Company.
Vi vorrei rivolgere i miei più sentiti complimenti per il lavoro che svolgete, e il senso di orgoglio che mi compisce nel pensare che un’azienda italiana lavori in questo modo. Ho iniziato a suonare anche grazie a Voi, e questo ve lo devo.

…My first reaction, when I installed this strings, was to tell myself to send Aquila a message and proclaim the guy who came up with these red label strings to be a genius! (Probably tired of hearing that by now…)
M° Domenico Lafasciano
Ho avuto il piacere di provare le corde armoniche Aquila.
Ottimo prodotto, con perfetta intonazione, bellissima cantabilità, prontezza d’attacco,
fascino nel vibrato.
Inoltre la loro lunghezza e morbidezza, rendono anche piacevole il noioso lavoro del cambio
di corde.
Le userò e le raccomando vivamente !
Phil Doleman – UK
…Anyway, as a user of your uke strings for as long as I can remember (at least 10 years I’m sure)….I’m not asking for free products, simply to share the fact that I love your strings!
Taro Tamura – Japan
I have web shop ”Spain Guitar Online Shop” in Japan. I have sell mainly Classical guitars,Flamenco guitars and Ukes. I am interested in your ukuleles strings. It’s fantastic.
Seoung Don Min
We’re so satisfied with your product.
Thank you for everything and honored I like this nice bright tone and rapid attack response.
also I think (as you written down the back of the pack) tone stability is quite nice
David Stanley – UK
…My set of Alchemia lasted over four months without losing their tone or their volume. That is a big compliment to the strings. Other strings would occasionally last me six weeks, other strings normally only last me about two weeks!
Eventually I got my banjo tuned to standard G tuning….
I had to shorten a couple of the strings because of too many wraps around the tuner post, but now it stays in tune.
I love these Nylgut strings…
Julian Roach – UK
… After two weeks of playing on them every day I am still delighted with them….I find them molto cantabile, with excellent sustain, quick in their response and highly responsive to variation in touch. They bring a new kind of sound out of my Sakurai-Kohno, a very ’alive’ kind of sound. I normally play on D’Addario Pro Arte, which I regard both as excellent strings and good value. Alabastros cost a lot more, but I will pay the difference for their distinctive charm. I thought you might like to know that you have a customer in the UK who is very pleased with your strings…
James Everhart – USA
…I thank you very much for your service. As well as the quality of your product. I am a fan of Aquila strings for life.My ukulele says thank you very much! Have a Great Day!
Andre Hendriks – NL
A ukuleleshop is not complete whitout Aquila strings
M° Stefano Aruta – Italy
… ieri ho ricevuto le 12 mute di AMBRA che avevo richiesto, ho montato una nuova muta e sento il bisogno di ripeterti quanto detto al telefono a mio parere sono le migliori corde oggi reperibili.
…il mio parere è frutto di una esperienza quarantacinquennale …
Innanzi tutto ho sempre insegnato ai miei allievi che la musica è l’arte di organizzare i suoni ma la matrice di tutto è il suono in sè come mero epifenomeno ed al di la di ogni banale considerazione su potenza , durata , sustain ed altre simili amenità ti ringrazio perché attraverso la tua ricerca hai ridato nobiltà al suono della chitarra , si vede che dietro al tuo lavoro non vi è solo una mera ricerca commerciale , ma un affanno teso alla ricerca del bello in modo da mettere noi musicisti in condizione di dare il meglio…
Michael Malley – USA
…I love the low g red series for the Ukulele. On my concert uke it works great…
George Charalampidis – Greece
…I love the sound of Aquila’s Nylgut for Oud and I do not want to buy strings from another company…
Michael Curry – USA
Alabastro, basses were nice and round, with plenty of edge to cut through, a very good string with lots of volume….
Nylgut- Extremely dynamic string, these are loud with better tone than carbon strings, all the brightness one would ever wantI would keep them on 2 of my 5 guitars though, because the grip on them is amazing, the unbelievable dynamic range, and they are warmer than carbon…. I must admit, I have been using very clear nylon strings over the yearsso nylgut was a nice in-between alternative, I think I will buy more in the future for sure..
The Bionylon felt great under my fingers, and I loved the sustain when I would do a glissando.

…I have used your strings for years and love them…
M° Massimo Gasbarroni – Italy
Come le accennavo frettolosamente, anch’io come, credo, tutti i chitarristi di questo mondo, abbiamo sempre avuto il problema di reperire delle corde di chitarra con delle prestazioni meccaniche e sonore accettabili.
Quando ero studente, fine anni quaranta-cinquanta ho provato anche le corde di budello e di seta naturalmente.
Ma se andavano bene per piccoli spazi non erano certo adatte ad una moderna sala da concerto, come ad esempio il Teatro Petruzzelli, 3000 posti, dove tenni un concerto senza problemi.
Sembrerebbe, a meno di un colossale abbaglio, che con le sue corde io possa aver finito di soffrire…
Salvatore Pinto – ITALY
…sono bellissime, grazie. siete stati molto gentili continuerò a usare queste corde.
Steve Paull – Australia
The new Red Aquila strings have arrived.
I have tightened the lower G string up to the B above G with no problems.
Many thanks for your kindness and great service.
David Stanley – UK
On Nylgut strings…Many listeners have commented on their beautiful clear sound.
These are the best strings I have used in over 50 years of performing & teaching.
