Yes. The dot markers on the neck were removed with the frets and filled in with matching rosewood. The fret spaces filled with maple.
The whole neck was stripped, sanded and refinished, then coated in epoxy, to protect the wood from potential damage as you press the (metal) strings into it.
The markers on the side of the neck *the little white dots you see when you look down at the neck from a playing position, were also removed and filled in. Then new larger bright-white dots drilled and placed in the correct position.
Remember, with fretted basses, these markers are between frets, because that's where you put your fingers to play a note... but on fretless, you have to put your fingers where the frets are (or would have been) to get the correct note.
It was a brilliant job done by a master luthier. I'll post photos for you guys to see in a few.
