I think I said it earlier though, or maybe on another thread, but unfortunately in this business your reputation is everything. Walk into a studio with a Squier and they are immediately not going to take you seriously. Unless, of course, you are already a known commodity. Then, they are still going to hand you the studio MIA J bass.
I don't judge a player by what he plays, but it happens. People judge you, we are human. What you look like is the very first, and often most powerful, impression you make. Since players in the biz know that SX, Squier, Schecter, etc. are all mostly beginner bassist instruments, with limited tonal variety, walk in with one and show off that headstock and first impression is that they are beginners or not that experienced and skilled. Or, not a serious musician. Sorry, but that is what happens. If that were not the case then there wouldn't be soooooo many basses out there that are not Fenders but someone has placed a Fender decal on it.
Most audiences in the bar or on stage could care less. I think most of the time I get comments and compliments on the color, style or shape of my basses, not what brand. I had a girl recently tell me how sexy my bass was and how cool I looked with it. It was my Seafoam Vaccaro Gen X. Forget the fact that the bass sounds killer, and also she didn't notice I really f'd up that night (too much tequila) just how sexy my bass was.
I'm not a gear snob, I play and own what I like. Which, as most of you know, are headless basses primarily. The design always resonated with me, and the fact that they have tones I enjoy just made it so much better.
I own custom Brubaker and import Brubaker. Never been judged on that yet, but the time I'm sure is coming....
