The Apollo Series is the perfect harmony between old and new. With a wooden body and carbon fiber neck, you’ll get an experience unlike any electric bass on the market.

  • Angled Headstock

    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 guitar 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.

  • Neck Features

    The bolt-on detachable neck is not the primary purpose of the guitar, 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 guitar is not designed to be a travel guitar, it’s designed to be your go-to electric guitar. Since guitars in general are very portable, making them durable and easy to travel with is naturally the best solution.

  • Neck Design

    An electric guitar neck 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 Heel of the neck is the same thickness of the neck itself which is not possible with wood. 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.

    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.

Designed to stay out of the case

While most high end guitars need to be kept in a case and babied, this guitar 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. is durable, with temperature and humidity having no effect. 

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.

Crafted With Care

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.
