As far as punters are concerned they have not the slightest clue. Most of 'em can't tell the difference between a bass and a guitar at two paces, let alone what type/brand it is. And anyway, by the time they engage you in conversation they're likely to be, er... 'not at their best'.
I don't care if another bass player mocks my bass, either. If he doesn't understand that a *insert name of budget or unusual brand* can be a good sounding, playable bass then what kind of bass player is he anyway!? The half-witted, suppurating pile of pus!
