Aquila B-Blacks Ukulele Strings: The Dark Side of Tone (In the Best Possible Way)

If you've been searching for ukulele strings that deliver something a little different — richer, warmer, and with a depth that standard nylon strings simply can't match — the Aquila B-Blacks series deserves your full attention.

Aquila is one of the most respected names in ukulele strings worldwide, and the B-Blacks range represents one of their most exciting innovations in recent years. Available across soprano, concert, tenor, and baritone sizes, these strings have quickly become a favourite among players who want more from their instrument.

What Makes Aquila B-Blacks Different?

The B-Blacks are made from Aquila's proprietary black nylgut compound — a synthetic material developed to replicate the acoustic properties of traditional gut strings, but with far greater consistency, durability, and resistance to humidity changes. The distinctive black colouring isn't just for aesthetics (though they do look stunning on any uke). The black pigment is integrated into the material itself, which subtly alters the density and tonal character of the string.

The result? A tone that sits somewhere between the brightness of standard nylgut and the warmth of fluorocarbon — with a slightly fuller midrange, excellent sustain, and a satisfying depth that suits everything from fingerpicking to strumming.

The Full B-Blacks Range

🎵 Aquila B-Blacks Soprano or Concert Ukulele String Set GCEA – 180U

The entry point to the B-Blacks family. The 180U is a standard GCEA tuning set designed for soprano and concert ukuleles. If you're used to the bright, punchy tone of standard Aquila Nylgut strings, the B-Blacks will immediately feel more refined — still articulate and responsive, but with a rounder, more complex tone. Ideal for players who want to add a little character to a soprano or concert uke without sacrificing playability.

🎵 Aquila B-Blacks Soprano or Concert Ukulele Low-G String Set – 181U

For players who prefer the extended range of a low-G tuning, the 181U delivers. The low G string adds a full, guitar-like bass note that opens up chord voicings and makes fingerstyle arrangements sing. The B-Blacks compound keeps the low G balanced with the upper strings — no muddy or overpowering bass, just a smooth, even response across all four strings. A superb choice for solo ukulele players and those exploring more complex repertoire.

🎵 Aquila B-Blacks Tenor Ukulele High G String Set – 182U

The tenor ukulele has a naturally larger body and longer scale length, which gives it more projection and sustain than a soprano or concert. Pair that with the B-Blacks 182U in high-G tuning and you get a tone that is genuinely impressive — clear, warm, and with a resonance that fills a room. Whether you're playing jazz chords, classical arrangements, or contemporary fingerstyle, the 182U brings out the best in a tenor uke.

🎵 Aquila B-Blacks Tenor Ukulele Low G String Set – 183U

The 183U brings the low-G experience to the tenor platform. With the extra scale length of a tenor, the low G string has even more room to breathe, producing a rich, resonant bass note that complements the warmth of the B-Blacks compound beautifully. If you play a tenor uke and haven't tried low-G tuning yet, this set is the perfect introduction. And if you're already a low-G convert, the B-Blacks will take your tone to the next level.

🎵 Aquila B-Blacks Baritone Ukulele String Set Wound D&G – 184U

The baritone ukulele is tuned DGBE — the same as the top four strings of a guitar — and it demands strings that can handle the lower register with authority. The 184U features wound D and G strings alongside plain B-Blacks upper strings, delivering a balanced, full-bodied tone that suits the baritone's deeper voice perfectly. Whether you're a guitarist making the transition to ukulele or a seasoned baritone player looking for an upgrade, the 184U is a revelation.

Who Are the B-Blacks For?

The Aquila B-Blacks are a brilliant choice for:

• Intermediate to advanced players who want to explore more nuanced tone from their instrument
• Fingerstyle and solo players who benefit from the added warmth and sustain
• Players upgrading from factory strings — the B-Blacks are a significant step up from the strings most ukuleles ship with
• Anyone who finds standard nylgut too bright and wants something with more body
• Performers and recording musicians who need consistent, reliable strings that hold their tone under pressure

How Do They Feel to Play?

One of the most common questions about any new string set is how they feel under the fingers. The B-Blacks have a smooth, slightly matte texture that feels comfortable from the first note. They settle in quickly — typically within a day or two of regular playing — and once they're up to pitch, they hold their tuning reliably. The tension is well-balanced across the range, making them comfortable for extended playing sessions without fatigue.

Changing Your Strings: A Quick Tip

When fitting any new ukulele strings, stretch them gently after installation and retune several times before your first session. This accelerates the settling-in process and gets you to stable tuning faster. With the B-Blacks, you'll notice the tone opening up and becoming richer over the first few hours of play — they genuinely improve as they bed in.
