Aquila 155C Sugar 6 strings Classical Guitar Normal Tension

Designed in three degrees of tension normal 155C, superior 156C and extra 157C (the latter 157C to be used only for flamenco) and with a trasparent look that resembles crystal glass, the Sugar Guitar Trebles are made using a recently discovered Italian blend of a plastic material derived from sugar-cane.

The sound of these strings is clearly brilliant, clean and prompt, and provide great acoustic power. Unlike Fluorocarbon strings, these strings have an excellent vibrato and a remarkable timbre variation when played very close to the bridge and then up over the sound hole. Laboratory tests showed that Sugar strings have a projection of sound (measured in Joules) and a sustain respectively 24% and 18% more than fluorocarbon strings.

These strings have, in their extremes, the sweetness and singability of gut and the clearness and promptness typical of Fluorocarbon. Another important property is the characteristic sustain, which by scientific measurements is superior to any type of string currently available in the market. Another measured feature is the sound projection: our scientific tests have shown that it is superior to Fluorocarbon strings. Although the surface is extremely smooth, the grip on the fingers is remarkable; in other words it is never slippery.


In the event of a squeaking sound that appears at the beginning under the right hand fingers, it is suggested to use a hand lotion, or even better a softening paste used to adhere to sheets of paper

Love/Hate: Superior tone & projection: Beware the "squeak" and short life.
February 22, 2020
I have a love/hate relationship with these strings. First of all, they are LOUD! Equipping a concert instrument with these will (finally!) give a player a fighting chance of matching the projection of our arco cousins. But beyond volume, the tone is simply incredible; beautiful and complex. The basses have tremendous layers of harmonics that compliment their strong fundamentals, and their even tension means intonation is quite good up the neck. The treble strings are what give the product its name, though, Made from a sugarcane polymer (a bio-derived polyethylene), the trebles each carry their own personality. Uniformity was apparently not the goal here- and that is not a complaint! The 3rd (G) string is shockingly clear and vibrant- far superior to the lifelessness tone usually attributed to this string in their nylon and carbon varieties. You will definitely want to re-voice melodic material to exploit this clarity (and welcome the reduction in position shifting). The 2nd (B) string shares the 3rd's clarity, and matches well while giving the notes a noticeably lighter personality. The 1st (E) string can be a bit temperamental; even a small kink introduced when stringing will keep the string from ringing clear and introduce profound ghost harmonics. But assuming stringing goes perfectly, the 1st string rewards with a snappy and percussive character that sacrifices a touch of sustain for vibrancy, as well as effortless, vocal-like vibrato.

But alas, nothing is perfect. While I already mentioned the fragility of the 1st string, it must be noted that all the strings in this set are incredibly soft (in terms of their resistance to wear) and unless you are playing on perfectly smooth and polished frets, you can expect de-lamination of the basses to occur within a month, and noticeable wear on the trebles as well. Granted, this may be a symptom of the unfortunate trend to use (ghastly!) stainless steel frets on modern instruments as opposed to more traditional materials, so if you have frets made of softer metal (e.g., nickel/copper) this may be a non issue.

But the greatest issue with these strings is, without doubt, the dreaded "squeak." Yes, the trebles squeak terribly while they are settling in, and sometimes even longer. This can be mitigated to an extent by constant playing and using hand lotion. Some players have suggested using very gentle buffing of the strings (1000 grit or higher sand paper) in order to remove the squeak, but given the fragility of the 1st string, this requires great caution.

Buffing the strings does, however, improve purchase of the fingers, which is another area where this string set has shortcomings. Appoyando feels very slick- perhaps too slick!- and does take some adjusting not to over articulate. Tirando is fine up to a point, but considering the aforementioned lack of finger purchase, this could make faster passages impossible without conditioning the strings (not to mention immaculate fingernail grooming).

But alas, the tone is the thing! If you are willing to treat these strings with far more care and consideration than a typical nylon or carbon set (venturing into the same gnatty level of detail and ritual usually reserved for authentic gut) you will be rewarded with a richness and variety of tone unmatched by other sets. Particularly, the profound variation from sul tasto to sul pont. is profound; even a slight change in positioning will reveal new colors. Pair that with the individual characteristics of the treble strings, and you get a set of strings that rewards the diligent player willing to explore where they can take their music.
ProsPhenomenal TONE Responsive, with wide tonal variations Individual string characteristics Impressively LOUD
ConsSoft and prone to wear Trebles will squeak without proper conditioning Finger purchase could be better, inhibiting speed

Great bright sounding strings
August 22, 2019
Made out of sugar cane, these strings are bright and powerfull. The bass strings are red in color and last longer than traditional silver coated strings. The treble string do have a squeaky sound that goes away with usage.

Sugar more fragile than nylon?
March 13, 2019
Strings have a very interesting sound. Nice sustain and plenty of volume, but is sugar more delicate/fragile than nylon? First string broke after only 6 days. Not at the nut or saddle, but right around the 3rd fret. Bought a few sets so I will try again and give it another chance. Maybe just got a bad set? Now with the new 50% increase (from $7.99) in price after the first 25% increase I'm not sure I'd buy them again if they keep breaking.
ProsLoud strings. Very nice sustain.
ConsSqueaks start happening out of nowhere but are minimized with any lotion applied to your hands. Trebles don't seem to last very long. You might need to change the compensation at the saddle as they are very good with intonation, or you might end up with flat notes past the 8th fret or so.
