Tenor Bass makes sense to me, since the instrument has some of the characteristics of a bass, but doesn't go low enough to sufficiently qualify as a bass. Ron Carter played one before Stanley or Victor.
I think that your supposedly improved tone from tuning this way is just a fluke related to your bass being not properly set up for EADG originally.
