Let's also be honest here:
If your drummer came in with new expensive cymbals, how many would notice?
" " snare " ?
if the saxophonist / trombonist / trumpets came in with a new horn of the same colour, how many would notice?
if the guitarist came in with a new guitar of the same type (sold body, hollow body, acoustic etc) how many would notice?
if the keyboardist came in with a new keyboard, of the same colour, how many would notice?
If people do notice, how many would actually say anything?

I do remember the first time I brought a Warwick Corvette to a rehearsal I was previously bringing a Fender Jazz fretless too:
Guitarist, " Are you playing a new bass?"
Me, "Yeah. Warwick"
Guitarist, "It sounds amazing, has a great modern edge." (paraphrasing, don't remember the actual words)
Me, "Thanks!"
Of course, he had to ask, because he's blind. So some folks do hear it!
Some.
Oh.. to add in: I've had other groups not like my bass tone but could not explain why. Switched the Warwick for the Fender and they liked the bass tone.
Ohh another. play the bass through a guitar amp, and folks will ask questions about what's wrong with the bass tone pretty quickly.
