Haven't seen an upright bass with frets, but then I haven't looked very hard. I always thought of a bass like a trombone; One either has to be very accurate, or very lucky.
It's not that long ago that I erased the magic marker dots from the white keys of my keyboard. I can read music, and know where middle C is on a keyboard or piano, but have to mentally count to find all the other notes

I envisioned having to "draw frets" on the neck of an upright bass
