A B-Stock instrument is merely cosmetically flawed. It is just as durable and beautiful sounding as a brand new instrument, however, throughout the manufacturing process, it has an imperfection that does not allow us to sell it as a perfect instrument. These imperfections are minor, ranging from a small scratch, a wave in the carbon fiber weave, a slight ding in the soundboard or neck, etc. Most people can’t even tell that there is an imperfection, but because we pay such careful attention to each detail, we are aware of them.

Tenor Uke, B stock, Wood neck, LOVE IT!

Love your website, easy to order. Got my Uke a day ahead of scheduled delivery. I love the sound and action. Changed the high G string to low G. My neighbor has a travel guitar, which he loves and when I saw Stu Fuchs, Ukulele Zen on u-tube playing one of your Ukes, I was sold on the idea of a carbon fibre uke.

What a beautiful item! I’m already enjoying its resonance and plan to practice more to justify its purchase. Just holding it makes me smile. It’s living on a stand right beside me to facilitate the grab and play experience. Communication with KLOS was a delightful experience. I’m very happy I invested in this item. My hedgehog is jealous.

Semi custom B stock

Ordered one with upgraded nut and bridge, the black tusk. A low G was also switched out. Impressed with the neck and spot on intonation which should not change due to the carbon fiber rods. Sounds good but even better when I changed the stock strings to Oasis brand, more separation of tones for picking and strumming. It’s a fun ukulele to play and the B stock rocks! No one can see the flaws, most are inside the uke. Now I can go to the beach in 80 degree sun and strum away without fear of warping the ukulele! The only drawback is changing strings, it must be done through the sound hole.

Very nice neck on carbon fiber body, B stock

Ordered the black tusk saddle and nut upgrade to improve string acoustics. I found all the areas that make this a B stock, but the flaws did not affect sound or function. I changed strings to a type that provides more definition and clearer sound, as I found the stock strings a little muddy. The action, intonation and sound volume, all good, were not affected by the string change,. Ukulele is very playable for the price range, frets are smooth at edge. Only inconvenience happens when you change strings, as the bridge is not the usual tie type, but through the saddle and out the soundhole, tie knot, then pull string up and secure as usual, (glad I could get my hand into the soundhole) hence one star off. Overall, it’s definitely a great travel / beach ukulele!


Like driving a Ferrari everywhere I take my KLOS electric ⚡️I get a WHOA Of admiration. Like a new baby I hand-it-over for admiring hands to strum and cuddle. They are amazed at the clear tone, solid heft and feel of the real deal. So far two friends have ordered their own! I am enjoying making music with my KLOS , I've named it SOLKie and carry it with me everywhere including outside events ( the beach even) and s(he) holds her tune and luster. Solkie and I make jubilant music and are not intimidated by any of the "K" models. Get a KLOS it's BOSS hmmm.. that should've been my headline
