Ships from our factory near Salt Lake City Utah
We are proud to have our factory located in the heart of the Rocky Mountains, which was the original inspiration for combining adventure with guitars. We are proud to do the design, assembly, and most of the building in our own factory in Utah, and we buy parts and materials from world renowned factories overseas. A big question we ask ourselves is: which part of the guitar building process requires the most skill, and impacts the player the most? The first half or the second half? Our answer: the second half. So we outsource some parts and materials (the first half), and keep the second half of the manufacturing process in house, and do it ourselves. This allows us to scale as a company and focus on building quality instruments that are incredible to play and listen to, which is our main goal.

Designed to stay out of the case
While most high end basses need to be kept in a case and babied, this bass was designed to stay out of the case, ready to play at all times. The KLOS Bass guitar is durable, with temperature and humidity having no effect.
Carbon Neck
Durable, reliable, and carefree. This carbon fiber neck is the ultimate bass guitar neck, with a composite ebony fretboard, minimalistic light weight headstock, fully adjustable truss rod, thin heel, detachable for travel, and perfectly shaped profile, it’s hard to think of anything more you could ask for.


Detachable neck
The bolt-on detachable neck is not the primary purpose of the bass, but it is a nice feature that is great in those moments when you need to put it in a suitcase or you are in a crunch for space. This bass is not designed to be a travel bass, it’s designed to be your go-to bass guitar. Since bass guitars in general are very portable, making them durable and easy to travel with is naturally the best solution.
Carbon Fiber Pickguard
While plastic pickguards have been reliable and used for decades by many bass brands, the KLOS carbon fiber pickguard takes the concept of a pickguard to a whole new level. Having a fully loaded pickguard has a lot of benefits. With all the knobs, switches, and pickups, wired together, it makes it easier to manufacture, and allows the end user to make future customizations a breeze. Now with having the KLOS pickguard being carbon fiber, we introduce the best of both worlds, being convenient, and having the superior look and feel.


Playability
Achieving the perfect playability is an art. The nut, fretboard, frets, truss rod, body, and bridge, all have an influence on the string playability, getting them all to work together perfectly is what makes a bass feel like home. Here at KLOS we take playability very seriously, that’s why we put a lot of attention into leveling the frets, filing the nuts, and adjusting the saddles. Each bass then gets played up and down the neck by our inspectors to confirm it’s worthy to go have a KLOS logo and go out the door.
KLOS Pro Aluminum/Brass Bridge
The perfect blend of performance and light weight. The aluminum body is machined from a solid block making it lightweight with precision quality. The saddles are individually machined out of brass to give the optimal sustain and sound transfer. The hardtail, string through bridge design also can be made to be string through body. For those who don’t mind the extra weight, we also have the option to have a solid brass bridge block. This bridge is as premium as it gets.


KLOS Pro Aluminum Knobs
The KLOS Pro Knobs are individually machined out of lightweight aluminum, resulting in a premium feel and unique style.
Body Wood
The KLOS bass body comes in 2 wood options, Okoume, and Ash, both of which are superior choices for a solid body bass.
Ash is used for it’s high density, strength, and the beauty of it’s wood grain.
Okoume is used because of its extreme similarities to mahogany, and while mahogany is currently becoming an endangered species of wood, Okoume is an excellent choice for it being a lightweight hardwood, and being unbelievably similar to mahogany for both tone and looks. Okoume, like mahogany, is less heavy than Ash, and is often chosen by many guitarists for this reason.


The KLOS Convert Gig Bag
The patented KLOS Convert Gig Bag, has the unique feature of having 2 modes of operation. It works as a standard gig bag when the bass is fully assembled, and also when the neck is detached, unbolted and collapsed. That’s right, the same bag works for when the bass is folded and when it’s fully assembled. When the neck is detached, the neck goes in the neck sleeve, on the side of the folded gig bag. The gig bag materials are made from the same stuff that camping backpacks are made out of, making it durable and reliable. With the bass itself being very durable, a traditional hard case is not as necessary for most day to day use, making the KLOS soft case gig bag is the perfect choice for the KLOS Bass.
KLOS Custom Shop Blackout Pickups (Passive Humbuckers)
These humbuckers blackout pickups have a flavor of traditional humbuckers with a modern touch. Durable injection molded casing with epoxy sealed internals, these pickups produce an articulate sound with a responsive feel. They can easily handle a wide range of tone from clean and quiet, to aggressive drive.
Standard is 3 knob setup with 1 neck Vol, 1 bridge Vol, 1 Tone. (Passive refers to no battery)


Active KLOS Custom Shop Blackout Pickups
Taking our premium KLOS humbucker pickups and wiring them with a 3 EQ pre-amp. This feature is available as an add-on, making it active with a 9 volt battery. The 5 knob configuration for this is 1 Vol, 1 Blend, 1 Bass EQ, 1 Mid EQ, 1 Treb EQ. This active pre-amplifier allows you to shape your tone even more to a wider range of sounds.
Fishman Fluence Soapbar (Active Humbuckers)
Original and totally re-imagined, Fishman Fluence pickups have 3 voicings with a coil split, which is like having 6 basses packed into 1, resulting in a wide range of tones that can play any genre. It’s thanks to the patented new technology that doesn’t use wire coils. The Fishman Fluence are free from hum and noise, even with the single coil voicing. The controls have the Push Pull the knobs to go to single coil, and a 3 way switch to choose the voicing. Standard wiring is with 4 knobs (1 volume, 1 blend, 1 bass EQ, 1 treb EQ).


Specifications for Fluence Bass Soapbar Pickups

Like all Fluence pickups, the Bass Soapbar pickups are multi-voice and are powered with a standard 9-Volt battery.
Custom Pickups! Choose your own pickups and wiring
One of the greatest design features of the KLOS electric and bass, is that you can easily customize the pickguard to fit any pickups and any knob configuration you want, and we will cut the pickguard and do the wiring. For musicians that are very set on a certain type of pickup, or knob configuration, we will cut the pickguard on our CNC, and solder all the wires and pots, and build you exactly what you want. If you ever want a new pickguard setup in the future, the KLOS carbon pickguard can be easily swapped out for a custom cut pickguard to fit any pickup shape, position, and number of knobs. No need to buy a completely new bass, just because you want different pickups and knobs. (With this option, you provide the pickups, pots, switch, and exact wiring diagram)


Ratio Multi-Gear Tuning Machines
Ratio Tuners, made by Graph Tech Guitar Labs, have a different gear ratio for each string. Thicker strings have more teeth, thinner strings have less teeth. Makes tuning your bass feel and perform like a dream.
HipShot Bass Xtender for Drop Tuning
Upgrade your 4th string tuner on your bass to have the famous Bass Xtender, which allows you to instantly drop the tuning of your low string and then back up again with the flip of a lever. You can adjust the limit screw to precisely and consistently have the tuning you prefer. If you add this to your order we will install it for you.

About the design of the Carbon neck
A bass guitar neck is long and thin, which is why it is even more important that it is more strong, lighter and reliable than any wood neck.
The most common place for a wood neck to break is where the neck meets the headstock. With a carbon neck, this position is equally as strong as any other part of the neck, so you can rest assured that you have the strongest neck in the world.
The carbon neck has a truss rod like most wood bass necks, but it’s not for the purpose of strength, it’s for the purpose of adjusting the bow of the neck to the exact preference of every player. We adjust the truss rod to the most popular neck relief in our factory , but it can be easily adjusted by every musician with the included wrench.
The neck is a detachable neck that makes it easy to disassemble into a carry-on bag or suitcase. It is attached with 4 screws, like most bolt-on wood necks, but the KLOS carbon neck has metal threaded inserts, and uses machine screws specifically designed to make the neck removable. With a removable neck, traveling with the bass as a carry on, or putting the bass in a standard size suitcase is more easy than ever.
The fretboard on the neck is a composite synthetic ebony which does not expand or contract with temperature or humidity changes, or with time, which means You will never have sharp fret issues, and your great great grand children won’t either. The beautiful ebony-like fretboard is dense, durable and smooth.
The headstock is a compact shape, making the overall length of the neck shorter, with a 2+2 tuner pattern that still has the same spacing as a 4 in a row, making tuning your strings just as comfortable, yet feel lighter. The tuners are the heaviest part of the neck, so keeping the weight of the tuners as close to the body as possible, and having a lightweight carbon neck will make bass playing for hours even more enjoyable.


The headstock break angle is 11 degrees, making it the optimal angle to have the perfect string force on the nut. This lowers the friction of the string on the nut, which lowers the chances of your strings going out of tune on their own, and makes tuning your strings more precise. When you look at the neck from a front view, you will also see that the strings go in almost a straight line, which also lowers the friction on the nut, which also helps create optimal tuning.
The Heel of the neck is the same thickness of the neck itself which is not possible with a wood bolt on neck. This makes the neck feel the same as you play in the higher frets. This design achieves that seamless feel similar to a one piece body and neck.

Apollo Pro Bass
I got my apollo pro in golden brown (transparent ash) with solid brass bridge and saddles, and fishman fluence pickups. I have played out with it several times. The sound and sustain are so good and the action is like butter. I love this instrument!

Apollo bass
Fantastic basses and an incredible price!!!


Excellent!
Oh man, what a beauty! This guitar looks fantastic with it's deep blood red body and snazzy carbon fiber neck and pickguard. The all black hardware looks super as well. It is short and surprisingly light, just a very comfortable and well balanced instrument. It sounds great and plays wonderfully. A very nice addition to my collection and one which will be getting a ton of playing time this year.

carbon at a wood price
totally happy, it all went super smooth

A Valuable Addition
I had to wait quite a while for it to arrive, and then the screws to assemble it were missing. I finally got it assembled and started playing. It took a few sessions before it would hold the tune. Once I got that worked out, I found it very easy and enjoyable to play. Once I get this off, I think I’ll play it some more!
