Convertable bass?

[Proletarian]

No doubt I am entirely behind the times on this, but it showed up on suggested Youtube today and found it quite interesting


YouTube - ‪Convertable bass (fretted/fretless)‬‏

This bass pops up from time to time on Talkbass, but ultimately, it generally costs about as much as a nice fretted and fretless bass. It's a nice concept, but the fretless ends up having high action due to the fret height plus the fingerboard height.
