Full Carbon Tenor Ukulele B-Stock (Soundport & Low G Upgrade)

Regular price $1,409.00 Sale price$1,309.00 Save $100.00

Our B-Stock instruments are merely cosmetically flawed. They are just as durable and sound just as good as a mint condition instrument. At some point in the production process, a component on the instrument was blemished. This could show up as a scuff, dent, a slight wave in the carbon fiber weave, or another minor blemish. We put the same care and attention to detail into assembling all of our instruments, regardless of condition. We will never compromise on build quality. 


Our Carbon Fiber Tenor ukulele is durable, lightweight, and sounds great. Features a carbon fiber neck for extra durability. This uke is guaranteed to delight with its' sweet tones and delicate sustain.

A Uke for You

A harmonic blend of portability and performance, the KLŌS Tenor Ukulele ensures perfect playability and stunning stability.

Discover Carbon Fiber


Carbon fiber is extremely resistant to temperature and humidity, so our ukuleles stay in-tune longer and won't warp, bend or crack in different climates. You'll never have to tune in-between songs for the rest of your life.


Carbon fiber's stability coupled with our state-of-the-art PLEK machine creates an unmatched play experience. Glide on a smooth fretboard that has impossibly low action and no fret buzzing.


Carbon fiber's unique structure lets sound carry more cleanly through the material. Which means, you'll have a full-bodied sound with impressive projection and sustain on every strum and pluck.


Perfectly Playable

Low action and precision filed frets make a uke that's fun to pick-up-and-play.

Stunning Sound

Incredible action and perfect playability compose a beautiful sound. Hear the KLŌS difference for yourself.



Built from Tradition

We're taking classic instrument design philosophy and injecting vision of the future, making instruments you won't want to leave behind.


Your choice between two expertly crafted carbon fiber materials.


Our traditional black bi-lateral carbon fiber weave that you can see across all of our instruments since the beginning of KLOS. The sleek and defining "carbon fiber" style.

Carbon Timber

Like the look of wood but want the benefits of carbon fiber? Nickel-infused carbon fiber that's made to emulate the look of a wooden instrument with each instrument having their own one-of-a-kind pattern. Ideal for the traditionalist on the outside, but innovator on the inside.


Plug in and unlock your instrument's potential.
