Aquila Strings at Kirstein
Aquila Corde Armoniche was founded in Italy in 1991 and specialises in strings for modern and historical instruments. One of its key areas of focus is developing materials that combine certain tonal and mechanical characteristics of traditional gut strings with the practicality of modern synthetic materials. Nylgut, developed by Aquila in the 1990s, has become particularly characteristic of the brand.
Within the current Aquila range at Kirstein, the main focus is on strings for ukuleles. Strings for guitarlele are also available. Aquila covers different scale lengths, tunings and tonal preferences – from classic soprano and concert models through to bass ukuleles.
New Nylgut, Super Nylgut and Red Series – What Are the Differences?
New Nylgut is one of Aquilas characteristic materials. The New Nylgut sets available at Kirstein for soprano, concert and tenor ukuleles offer a defined, singing tone and clear response. Compared with regular nylon, Aquila and the respective product descriptions also specify a shorter stretching phase and better tuning stability. For anyone looking for a balanced Aquila string set for a classic ukulele, this is a useful starting point.
Super Nylgut is another material Aquila uses for ukuleles. It is designed to deliver a singing tone with more brilliance than conventional nylon. In the Kirstein range, Super Nylgut is used, among other applications, for multicoloured ukulele strings suitable for soprano, concert and tenor ukuleles.
The Red Series takes a different approach. In the ukulele sets available at Kirstein, Aquila combines Nylgut with red copper powder to achieve a higher material density. This allows the strings to remain relatively slim even for lower notes. In terms of sound, Red Series strings are designed for bright, defined reproduction and fast response. At Kirstein, you can find versions for concert, tenor and baritone ukuleles.
Aquila Strings for Soprano, Concert, Tenor and Baritone Ukuleles
When choosing a string set, you should first consider the ukulele size, scale length and tuning. For soprano, concert and tenor ukuleles, Aquila offers sets for the widely used GCEA tuning, for example. Depending on the set, either a high or low G string is used. A Low G version noticeably changes the character of the instrument and extends its range downwards, while High G retains the typical re-entrant tuning characteristic of the ukulele.
Baritone ukuleles, on the other hand, require suitable sets for their different tuning. Aquila offers Red Series strings for DGBE, among others. Your preferred material should therefore not be the only deciding factor: before changing strings, always check whether the set, tuning and scale length are suitable for your instrument. You can find an overview of instruments and sizes in the ukuleles category.
Thundergut for Bass Ukulele
For bass ukuleles, Aquila uses Thundergut. The Thundergut strings available at Kirstein are designed for EADG tuning and a 20-inch scale length and, according to the product information, are also suitable for U-Bass and Ashbory Bass. This makes the material a specialised solution within the Aquila range that differs significantly from the thinner string sets for soprano, concert and tenor ukuleles.
Aquila and the Tradition of Gut Strings
The study of historical strings is an integral part of Aquilas brand identity. Alongside its current ukulele range, the company manufactures and develops strings for classical guitars as well as historical plucked instruments and harps. In addition to Nylgut and Super Nylgut, the manufacturers wider range includes other materials and product lines such as Sugar as well as genuine gut strings. This combination of historical string making and material research shapes the direction of the brand.
If you are generally looking for suitable replacement strings for different instruments, the Kirstein Strings range provides an overview of the available string types. When making your choice, important factors include not only the instrument itself but also the scale length, tuning, desired tonal character and the intended application of the respective string set.
Why Buy Aquila at Kirstein?
At Kirstein, you can select Aquila strings according to their intended application and compare them with other string options. With ukuleles in particular, it is worth taking a close look at instrument size, tuning and material, as changing strings can noticeably affect tone, response and playing feel. If you have any questions about choosing the right strings, Kirsteins expert advice is available to help. The 3 Year Kirstein Warranty also applies in accordance with the applicable terms and conditions.
