Carbon fiber is used to build airplanes, car parts, hockey sticks, tennis rackets, high-end bicycles, golf clubs, and many more parts that undergo much more stress than a guitar ever experiences. Carbon fiber is a combination of the most durable weave fabric and the strongest epoxy glue. Together, the two combine to create an incredibly hard, solid, strong and light material. Watch our video where a car runs over our carbon fiber ukulele if you want to see how strong our instruments are!

Sound is very subjective. We don't claim that carbon fiber sounds better or worse than wood, it just sounds different. Our customers have told us consistently that their KLŌS travel guitar is much louder than they would have expected given its small size. Because carbon fiber is so strong, it requires less internal bracing, which allows it to resonate more freely.  We recommend reading our customers' reviews on Google or Facebook, or on our guitar product pages, as well as watching some of our demos in our Videos section. Smaller guitars should not be compared to normal size (ie full size) guitars because the smaller cubic volume of the body itself has limitations, independent of material composition.   

On our Hybrid Series models, the body and soundboard are made from carbon fiber, and the neck and bridge are made from mahogany and walnut.

Our Full Carbon Series models are made completely from composite materials such as carbon fiber and richlite.

Our hybrid models are made with a mahogany neck and bridge, with a carbon fiber body. What sets our wooden necks apart are the two carbon fiber stiffening rods that run alongside the truss rod. These help the neck be more resistant to warping and bending than an average wooden guitar.

Our full carbon series takes wood out of the equation, with a carbon fiber composite neck, fretboard, and bridge on our carbon fiber body. This full carbon build is extremely damage resistant, nearly weather-proof, and won't ever bend, warp, or crack on you. They also have a better sound to them as well. This is due to the guitar being one uniform material, which allows for everything to vibrate at the same frequency. The composite bridge especially helps to bring a fuller, richer, and warmer tone.

Which one is better for you may vary, however. Both are durable, but the full carbon series is much better if you plan on taking your KLOS in a hot or cold car for long periods of time, or on long outdoor trips. They are also best if you are looking for the best sound quality out of your KLOS! However, some players just like the feel of a wooden neck, or need a more affordable option, in which our hybrid series can still provide you the durability and longevity that KLOS is known for!

First and foremost, the wooden neck feels familiar in your hand. It also helps reduce the production cost, allowing them to be half the price of other carbon fiber guitars. The wooden neck is still incredibly durable because of the wood we use and the carbon stiffening rods we add to resist warping and twisting.

We also want to offer customers the ability to have a more affordable option, while still having the opportunity to take advantage of the durability KLOS is known for!

Our Hybrid Series guitars feature carbon fiber stiffening rods in their necks. Most guitar necks have a truss rod which allows the player to adjust the relief of the neck. In various environments, dry vs humid, hot vs cold, wooden necks expand or contract differently and the curve of the neck can change slightly. When you adjust the relief with the truss rod, you can offset some of these changes. Carbon fiber stiffening rods provide a constant and unchanging element that runs the length of the neck. This can minimize the effect of temperature and humidity changes. So once you have the truss rod set correctly, environmental changes will not affect the neck as much.

Please note that all wooden necks, including ours, are inherently susceptible to warping and twisting over time if exposed to temperature or humidity extremes.

No! The carbon rods weigh less than the wood they replace, so they make the neck slightly lighter.

Unfortunately, we don't offer the ability to solely upgrade the neck on your hybrid guitar to carbon fiber. However, we would love to get a full carbon series instrument in your hands, so be sure to reach out to us at info@klosguitars.com for more info on how to get that upgrade done!

The composite ebony fretboards featured on KLOS instruments does not need to be conditioned in order to be maintained. If your fretboard does get dirty, just some butcher block conditioner on a clean microfiber cloth should do the trick!

We are partnered with physical retailers in these locations.

We're expanding our dealer network every day, so please let us know if you have a favorite music shop that you'd like to see carry KLOS guitars and ukuleles!

Yes! We currently ship to all countries apart from Russia and Ukraine until further notice.

Shipping varies on location, and may be more or less than any general estimate we can make here. We recommend adding a guitar to cart and putting in your information so that our website can tell you exactly how much shipping costs.

You will also have the option to pay your country's required duties and fees at checkout, or upon your order's arrival!

Don't panic! Your bolts, saddle, and screwdriver set should all have come with your guitar. Be sure to take a look at the vertical pocket on the front of the gig bag. This pocket will be on the same side as our logo on the neck portion of the bag. Inside, there will be a ziploc bag with all the items you need to assemble your KLOS Guitar!

You won’t find a better guitar to travel with by plane! While in backpack mode, a KLOS travel guitar can not only be stored in the overhead compartment, but also be taken aboard as a personal item and placed under the seat. The screwdriver to assemble and disassemble is also TSA approved, so you won’t have any issues taking your travel guitar with you on your next flight!

Our travel guitars have all the benefits of your standard acoustic dreadnought, but in a smaller, more portable package! The KLOS travel guitar has a ¾ scale body of our full size, but still has a full size neck and 24.75” scale length. They are also substantially slimmer, at about 3.5 inches on the lower bout.

Our full sizes are still great for traveling, and can be disassembled to make for better portability. While in backpack mode, a KLOS full size guitar can be stored in the overhead compartment. The screwdriver to assemble and disassemble is also TSA approved, so you won’t have any issues taking your guitar with you on your next flight!

Our full size guitars are just a hair shorter than the standard dreadnought, and a bit slimmer at about 4 inches on the lower bout. They still pack the same great volume of a dreadnought, however.

There are a few main differences between our standard and deluxe ukuleles:

• Our standard ukulele will be acoustic, while our deluxe will have a Fishman Kula pickup installed. This is an active preamp pickup with a piezo system. It also has an onboard tuner and some EQ options!
• The standard ukulele will have our KLOS machine heads, while the deluxe will have upgraded Graphtech Ratio tuners.
• The hardware will also be upgraded from the standard Nubone nut and saddle to the Graphtech TUSQ saddle and nut.
• The strings will also be upgraded from the D’addario EJ65T clear nylons, to D’addario EJ99T fluorocarbon strings.

Yes we do! You can find that option on our full carbon ukes, both for tenor and concert. It will be on the instrument page alongside our other custom shop options.

Unlike our guitars, and basses, our ukuleles have set necks. Our hybrid ukes have a glued neck, and our full carbon ukes are one piece.

Though our guitars and basses have radius fretboards, our ukulele fretboards are completely flat with no radius.

Yes, you are able to get custom pickups in your Apollo guitar! Just be sure to select our “Custom pickup, knob, or tremolo configuration” option on the Apollo page before checkout. Once your order is placed, we will reach out to you within 1 business day to see what pickup/pickguard you were looking to have installed!

When you select the custom pickup option for your electric guitar build, we will reach to you by email and work out how you are wanting to set up your guitar!

We will typically have you send in your preferred pickups and a wiring diagram for custom builds.

Our custom series electrics will have a 25.5” scale length, with both 22 and 24-fret neck options.

Our Vector and old-style Artemis electrics will be 24.75" by default, with a 24-fret 25.5" scale length neck option as an upgrade.

We have the option to put either a true Floyd Rose on your electric guitar, or a Wilkinson Tremolo system. You can find that upgrade in the add-ons section of our custom series electrics.

Yes, you are able to get custom pickups in your Apollo bass! Just be sure to select our “Custom pickup, knob, or bridge configuration” option on the Apollo page before checkout.

Unfortunately, we only have one scale length for our basses at this time. However, if you are interested in seeing a short scale version of our Apollo basses, be sure to fill out an instrument interest form here.

Unfortunately, at this time we aren't offering a steel string option for our Baritone ukes.

Currently, the baritone only comes in the Full Carbon series.

We don't have an f-style mandolin in production yet, but hope to have one launched in late 2025 / early 2026. Be sure to keep up with our mailing list so you know when that release happens!

The front strap button is going to be an optional button at the base of the neck. Every mandolin will come with a strap button at the bottom of the instrument by default.

We are able to accommodate some custom hardware. If you are interested, reach out to us at info@klosguitars.com.

While we don't have any other nut widths available, we do have three string spacing options to help you get your desired playability. Those will be Traditional (24.8 mm) / Wide (26.5 mm) / Narrow (23.8 mm).

Traditional is default, while wide and narrow are availble as a $40 upgrade.

As of right now, we only have our Fender replacement necks that are made to match their exact specifications. To test the compatibility of your guitar with our necks, you'll have to check on its neck pocket dimensions and make sure they line up with the ones over on our site (Fender's neck pocket dimensions). With that said, we are considering doing necks for other brands in the future, but we're going to see how this one goes first for the Fender electrics. You can sign up for any other neck here: https://forms.gle/mDbdoEcKPERVP9hW6. We'll use this information when deciding what necks to make in the future! 

Yes! While the heel thickness will be the same, the Strat heel is rounded, while the Tele heel is flat.

The Strat neck has a 9.5” radius with a rounded bottom, while the Tele neck has a 12” radius and a flat bottom. However, we offer Strat 12", Tele 9.5", and 10-14" compound radius options as well.

Yes! You’ll also be able to mix and match heel and fretboard styles to find your perfect fit. For example: you can get a neck with the rounded Strat heel, and fretboard option 2: the 12” radius fretboard with a flat Tele end. These customizations will come at an additional cost.

All of our F-Series electric necks have 22 frets.

The frets will be made out of stainless steel and be medium jumbo sized with a width of 2.7mm.

The necks will only come with Medium Jumbo stainless steel frets.

You sure can! Because the fretboard will overhang, you will be able to replace a 21 fret neck with our 22 fret necks.

Both! Each neck will be drilled for both plate styles. So, whether you have a rectangular plate or an offset plate, the carbon fiber neck will fit snug and secure.

Both the Strat and Tele necks have a 25.5” scale length.

The necks come with a black GraphTech TUSQ nut and our KLOS chrome tuners. The option to upgrade to locking tuners will be available at an additional cost in the add-ons section.

We are open to customizing the nut string spacing for those who prefer more distance between their strings. Contact info@klosguitars.com for pricing and fulfillment.

We offer a "Hendrix style" lefty orientation for our necks. This means the bolt holes, inlays and logo will be in the correct orientation for a lefty, but the headstock will be in the right orientation.

We are able to make necks without front facing dots on the fretboard. Reach out to info@klosguitars.com for pricing and fulfillment.

Yes! We also offer chrome, black, and satin locking tuners. You can find those in the add-ons section.

The pick-guards will have have standard Fender shapes. Only the pickup, knob, and switch orientation will change, depending on your instrument.

Yes! You can upgrade to a lefty pickguard for your strat or tele for $50. An additional lead time will be necessary.

You can make modifications using standard tools to get your ideal pickguard. However, any modifications made will void the return policy.

Yes! We offer neck replacements for both 4 and 5 string basses.

We offer 20, 21 and 22 fret options. Each of these necks have a different heel length, but will match standard Fender heel sizes corresponding to the number of frets.

No, the width at the 20th fret and heel thickness is the same between the 20, 21 and 22 fret necks.

Unlike our F-series guitar necks, our F-series bass necks will ship without threaded inserts. Customers will be provided instructions on how to tap the aluminum plate in the heel and create a thread to match their bass body.

Yes, our necks work for 4 and 5 bolt patterns.

The frets will be made out of stainless steel and be medium jumbo sized with a width of 2.7mm.

We do have a fretless option available in the add-ons section. By default, these will still have front-facing fretboard markers, and will be lined.

The bass necks will have a 34” scale length.

The necks come with a black GraphTech TUSQ nut and our KLOS chrome tuners.

We are open to customizing the nut string spacing for those who prefer more distance between their strings. Contact info@klosguitars.com for pricing and fulfillment.

There are 2 options: Jazz nut width (38.1 mm), and Precision nut width (41.3 mm). The heel on both these necks are exactly the same, so the necks are interchangeable.

All necks will come with a 12" radius by default. We also provide a 10-14" compound radius upgrade option.

The 5-string replacement necks will have a 48 mm.

We offer a "Hendrix style" lefty orientation for our necks. This means the bolt holes, inlays and logo will be in the correct orientation for a lefty, but the headstock will be in the right orientation.

We do sell factory second guitars at a reduced price. You can find those here.

A factory second guitar is merely cosmetically flawed. It is just as durable and beautiful sounding as a brand new guitar, however, throughout the manufacturing process, it has an imperfection that does not allow us to sell it as a perfect guitar. 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.

Please read our return policy.

Read about our warranty here.

This will depend largely on what model you have, and what model you are looking to get. We are unable to exchange any instruments from customers that have custom shop options at this time.

Be sure to reach out to info@klosguitars.com for more info if you are interested in exchanging your instrument. Restocking fees may apply.

We use standard nickel silver fret wire for the majority of our necks. While some necks have stainless steel frets, we are currently not able to offer stainless steel frets on instruments that have nickel silver frets. Please refer to each instrument's specifications for more details on neck materials.

The side sound port is a second sound port (1.75" diameter) in the upper bout on the side of the guitar. It helps get the sound from the strings more directly to your ear. It doesn't replace the main soundhole. 

Check out our info page about the side sound port here

It is very easy to attach and detach, check out this tutorial video.

You only have to detune the strings and remove four screws. Since our guitars are so small, it's pretty easy to take it with you without detaching the neck.

Our guitars are assembled by hand in Provo, Utah by our team of luthiers.

We've made a video about how and how often to maintain your KLOS guitar. 

You can find our shop's default string set for each instrument in its respective Product Specs section. If you are interested in further recommendations, feel free to reach out to us at info@klosguitars.com

Our standard action on a guitar will be 6/64 on the low E, and 4/64 on the high E, as measured at the 12th fret.

There is a battery pack above the low E string (same side as the volume and tone knobs). The best way to change the battery is to loosen the strings, reach in the soundhole, find and open the Velcro battery pack, and replace the 9V battery. The battery has an estimated lifetime of 100 hours before it should need to be replaced. 

Our acoustic-electric and deluxe models are similar, but there are some key differences that make our deluxe a higher-end product:

Our deluxe has a complete hardware overhaul, including an upgraded nut, saddle, bridge pins, and machine heads! There is also a Graph Tech TUSQ nut and saddle installed, with upgraded bridge pins. Finally, instead of our standard KLOS tuners, the deluxe model will have GraphTech Ratio machine heads. All these combine to make a greatly improved model over our already awesome standard instruments!

Yes! We wouldn’t want to forget our lefty players out there. Any non-cutaway acoustic instrument is available in a lefty build for deluxe hybrid / full carbon models.

We also have lefty options for our electric guitars and basses!

Yes! You can find a nylon string upgrade for all our full carbon guitars in the Add-Ons section.
