I've got 3 - a Jerry Jones single cut wearing flats, a Neptune shorthorn with roundwounds and a Neptune longhorn getting ready to wear tapewounds. Great tones, deep and thumpy but yet still focused. I really find them to fit in a lot of music styles and genre's. Super high quality and the necks feel wonderful. My only complaint has been the rather sharp radius on the edges but my local luthier has fashioned me a maple armrest that is really comfortable so these are my go-to basses right now.
Don, could you post a picture of the armrests your luthier made?
