The KLŌS Concert Ukulele was built for musicians who want a reliable, great-sounding instrument without the constant maintenance that often comes with traditional wood ukuleles. We designed this carbon fiber concert ukulele to deliver a crisp, balanced tone while staying stable through humidity, temperature changes, and real-world use. Whether you’re writing songs at home, performing on stage, or recording in the studio, this is an instrument that’s always ready when you are.
Our Concert Ukulele is a one-piece carbon fiber construction that sets it apart from traditional options. Unlike wood instruments that can warp, crack, or require careful humidity control, carbon fiber is incredibly stable. That means you don’t have to worry about seasonal changes affecting your setup, tuning, or playability. For musicians who travel, play outdoors, or simply want a low-maintenance instrument, this level of durability is a game-changer. Compared to many concert ukuleles from brands like Fender, Córdoba, or Martin—which typically use laminated or solid wood construction—our approach prioritizes long-term reliability without sacrificing tone.

Despite its rugged build, the KLŌS Concert Ukulele remains lightweight and comfortable, coming in at just around 1 lb 11 oz with a 15.25" scale length and 19 frets. The feel is familiar and approachable, making it easy for beginners to pick up while still offering the responsiveness and precision that experienced players expect. With a 1.40" nut width and smooth composite ebony fingerboard, the instrument feels natural for both strumming and fingerpicking styles. Combined with our PLEK-based setup process, we focus on delivering low action and clean playability across the fretboard, so you can spend more time playing and less time adjusting.
We designed the Concert Ukulele to be bright, articulate, and balanced. Carbon fiber allows for efficient energy transfer, which results in clear note definition and impressive sustain. Players often describe the sound as crisp and “bell-like,” with enough warmth to support vocals while still cutting through in a mix. The concert size sits in a sweet spot for many musicians—it offers a slightly fuller voice than a soprano while maintaining a lighter, more nimble feel than a tenor. That makes it an ideal choice for singer-songwriters, casual players, and performers who want a versatile, expressive instrument.
For musicians who need to plug in, we offer an acoustic-electric configuration that includes our KLŌS Concert Pickup system with an integrated tuner. This active piezo system captures both string and body vibration, producing a bright, clear amplified tone that works well in live and recording environments. The onboard tuner keeps your setup simple and efficient, eliminating the need for extra gear. Whether you’re going straight into a PA system or recording through an interface, the plug-and-play design helps streamline your workflow so you can focus on the performance.

When it comes to value, the KLŌS Concert Ukulele sits in a premium category, and that’s intentional. Entry-level models from brands like Fender or Córdoba may come in at lower price points, while options like Martin offer more durable laminate builds, but these instruments still rely on traditional materials that can be sensitive to environmental conditions. With KLŌS, you’re investing in a carbon fiber concert ukulele that’s built to last, perform consistently, and reduce the long-term costs and frustrations of maintenance. It’s not just about the initial purchase—it’s about having an instrument you can depend on for years.
We also back that philosophy with practical ownership benefits. Each ukulele includes a durable gig bag designed for everyday use, along with upgraded components like a Graph Tech nut and saddle for improved tone and stability. Our limited lifetime warranty reinforces our commitment to quality, giving you confidence that your instrument is built for the long haul.

Ultimately, we created the KLŌS Concert Ukulele for musicians who want freedom—freedom from climate concerns, from constant adjustments, and from fragile construction. It’s a durable travel ukulele, a reliable stage instrument, and a studio-ready tool all in one. If you’re looking for a carbon fiber concert ukulele that delivers bright tone, effortless playability, and long-term value, this is exactly what we built it for.
