Yes, I read every word of it, more than once, and still see no correlation AT ALL between "groove" and the number of strings on your bass. {"Less notes" is about attention to rhythm, being very aware of AND APPRECIATING the space in the music, and FAR more interested in the combined result of the efforts of the ensemble than making sure you get in your licks.} None of this has to do with the number of strings on your instrument. Nor do I understand what is literal or implied about "sensibility"?
Players groove, basses don't.
I have no need or interest in defending my position for what I play. Nor should you.
In the right setting, I could play a four all night and be as happy as a bug in a rug. I do it all the time on my DB gigs. But, if I am playing a Gospel number in Eb or D, there's no getting around not having those root notes in the "bass" range without alternate tuning, which I absolutely despise. So, I bought a five.
If I am coming off strong, forgive me.{ But,this discussion has been done ad nauseam at TB and seldom with any merit.}
