Stunning Sound

Carbon Fiber Pickguard

The KLOS carbon fiber pickguard takes the concept of a pickguard to a whole new level. Highly modular as well as resistant to dents and scratches. Plus, let's be honest, it looks cool.

KLŌS Blackouts (3-Knob)

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. 

Fishman Soapbars (4-Knob)

The Fishman Fluence Soapbars are multi-voiced active pickups. Get a range of sounds from classic, funk and jazz all in one bass. Use both pickups, or switch to just one, with just a push or pull of the volume knob. 


KLŌS Blackouts (5-Knob)

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.

Custom Pickups

Because the Apollo bass is so easy to customize, you can choose which pickups you'd like on your bass, ship them to us, and we will cut the pickguard as well as do the wiring. If you start with the pickups we have, but find that they don't quite fit your style, you don't need to buy a new bass. Contact info@klosguitars.com, and we'll find a solution that works for you.

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. 

A look at the two wood types used to make Apollo instruments (ash and okoume wood)
Wood Body

The KLOS electric and bass body comes in 2 wood options, Okoume, and Ash, both of which are superior choices for a solid body guitar. 

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. 

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 saddle screws are precisely designed shorter so they feel comfortable and don’t dig into your palm. The hardtail, string through body design provides the downward string pressure for the saddles, bridge, and body. This bridge is as premium as it gets. 

Simple graphic showing the KLŌS gigbag converting into a backpack
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 guitar is fully assembled, and also when the neck is detached, unbolted and collapsed. That’s right, the same bag works for when the guitar 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 guitar 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 guitar.

Ratio Multi-Gear Locking 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. 

A look at the different ratios the Graphtech Ratio tuners offer
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.
