BUT.
Yeah, there it is, the "but".
It has a minor-to-moderate dead spot on the 5th fret of the A STRING which is really deterring my enjoyment. Dead spots on the G string, I don't care that much unless they are very noticeable. The D note on the A string, however, is another story...
I'm sure that Sadowsky flats, being somewhat vintage in tone and vibe, are amplifying the issue. But, I really like these strings. I'm quite sure they are mounted correctly, also.
Anyway, adding some mass to the headstock seems to help with it, so I'm going to order a Fat Finger and give some feedback about it later, I don't want to give up on a bass I bought new for a special occasion. It's perfect, otherwise.
Can't really blame Sadowsky as well, since dead spots are a fact of life. Just got unlucky I guess.
