True story: I was recently at a jam, and there was another bassist there. I opened my case, and before I even played a note, he said "I'm not as good a bassist as you". I asked him why he would say that, and he said it was because I played a sixer. Then he opened his case and pulled out a 4-string. An unlined fretless 4-string. And then it was my turn to sweat.

If bringing the six to the audition costs you the gig, consider that a bullet dodged, because there's probably plenty more stupid where that comes from.
