F-STYLE SOUND DEMO

WHAT PLAYERS HAVE TO SAY ABOUT OUR MANDOLINS

★★★★★
This is a great mandolin all on its own. Sounds great, plays easily, plenty of volume, bark, and can be played sweetly and quietly when needed. Set up perfectly out of the box. The KLOS pickup is great, sounds extremely natural just plugged into an amp.
So it becomes a bonus that the mandolin is nearly indestructible. I can take it anywhere I want to go without worry.
Dave B.
United States

★★★★★
I was expecting to lose a little something not being wood but WOW was I wrong. This is truly an excellent instrument. You won’t be disappointed.
Rick B.
Canada

★★★★★
I realized that most mandolins up until now have been made with a 100-year-old perspective in mind. However, this mandolin is based on instruments from 100 years ago, but by incorporating everything that is currently possible, it has dramatically improved the level of perfection of the instrument.
Takashi U.
Japan

★★★★★
I’ve played my KLŌS carbon fiber mandolin every day since it arrived two months ago. It sounds, plays and looks so good it’s hard to put it down. It’s everything I had hoped for in a carbon fiber mandolin, only better.
Tom F
United States

★★★★★
The acoustic Klos Mandolin stays in tune with all the extremes on my road trip, humidity and heat, etc. It's fun and easy to play.
I just love the sound! Thank you for developing and delivering this product!

TRADITION X INNOVATION

ATTACHED SCROLL + SOUND PORT

The KLŌS F-Style Mandolin features an attached scroll that offers both the unique look and feel iconic to the F5 shape, while also providing an extra sound port that projects the balanced tone of an F-Style even more.

Unique Contours

Elevated contour lines adorn the scroll and points of the body. This unique shape makes the KLŌS F-Style stand out with an intricate beauty.

Perfect Playability

A slim neck profile combined with our PLEK machine and stainless steel frets offers a modern, sleek and faster playing experience.

Iconic Headstock

The KLŌS F-Style keeps tradition where it counts, boasting precise and machined headstock curls embodying the F5 legacy

PASSIVE

KLOS Transducer

The same transducer pickups as our active option, just without the preamp. We glue the transducers to the inside of the body for a clean look and worry-free play. Clearly amplify your own talent with this simple plug-and-play option.

K&K Mandolin Twin

The K&K Twin is a dual-head transducer pickup that is designed to be installed in the mandolin bridge. The two heads allow for a more accurate sound reproduction and a more balanced tone. The K&K Twin is passive and does not require a battery.

ACTIVE

KLOS Mandolin EQ

Specifically designed for the KLOS Mandolin, fully control your sound and tone with this easy to access active transducer pre-amp. Featuring an on-board tuner, a phase button to mitigate feedback, a low battery indicator and a quick-replacement battery box.

$250.00

Protect your mandolin with confidence using this premium fiberglass hard case, designed for exceptional durability and secure travel. The rigid fiberglass shell shields your instrument from impacts, pressure, and environmental changes, while the plush-lined interior cradles your mandolin in a soft, protective fit that prevents scratches and unwanted movement.

FAQs

The starting price of the F-Style Mandolin will be $3,799 USD to account for the extra complexity it takes to nail the F5 shape. Variations on material components and pickups will be priced differently. Be sure to checkout the link to the webpage above and click around the different variants to see exact pricing.

Check out the sound demos available on this page, as well as on our YouTube channel

We'll be able to ship the F-Style to most countries worldwide (including the UK and Canada).

Every F-Style Mandolin will be made with stainless steel frets. We want the consistency and durability of the frets to mirror the carbon fiber construction.

You'll be able to pick one of the following:

KLŌS Transducer (which is the default Acoustic-Electric pickup)

KLŌS EQ (uses the KLŌS Transducer as a base, but adds the ability to switch back and forth from active to passive)

K&K Mini Pure (a tried and true pickup for mandolin players)

The default tuners and tailpiece will be silver, and we'll be offering a gold plated tailpiece and tuners for an additional $200 USD.

Music Moves You

Where will it take you?
