The F King of Fretless.
More than just a bass without frets, the F is a creative weapon that takes you beyond the limits of the traditional fretless bass. An instrument endowed with amazing resonance and incredible clarity, attack, sustain. Impossibly light, comfortable, and balanced in a way you've never experienced before, the F was uncompromisingly designed to be only fretless and uniquely so.


The F gives you a consistent feel at any plucking position, so that nothing gets in the way with your creativity. Quite a little design (r)evolution had to happen for all this to work and it's pretty amazing how well it does.
The F is available as Hybrid-Headless (pictured), true headless or with traditional tuners at headstock; in any scale length and number of strings. As with every MüB, the list of available options is virtually endless.

First things first: The MüB-F is darn pretty. Minimalism at its best. Slim, sensual, perfectly ergonomic curves. Light as feather. Stiffer than the Salvation Army.

Fingerboard and top wood combos are, Gabon ebony, Asian ebony, Macassar ebony, blackwood, purpleheart, bloodwood, zericote, some acrylic impregnated wood. Basically any wood that works well as fretless fingerboard.

Here's a cool option: Due to their different gauges, strings bend on the saddles each at a different angle and the MüB-F self-adjusting tuners abide. No stress on the string. No stress on the tuners. Everything just works.

Like every MüB, the F is available in our Headless-Hybrid tuning system; with standard tuners at headstock and bridge by Hipshot, or as a true headless with MüB/ETS hardware.
