My gigging days are over due to a hand injury, but I never did and never would gig with a Squier for the simple reason it would be a distraction for someone.
The first time somebody asks himself, "Why is that guy gigging with a Squier?" I would have achieved an incremental presentation failure.
Same with anything that was non-pro-standard gear of any kind, or otherwise conspicuous, like in some hideous color.
My final "working" basses were a plain-vanilla MIA new sunburst P and a plain-vanilla new MIA sunburst J.
Pro-standard stuff nobody would give a second thought to, one way or the other. Nobody's going to love it or hate it.
I have much more valuable and impressive gear, but I wouldn't use it any more than I would a Squier.
The music is important and you're the show, as the performing musician. The gear's presentation should not distract focus from that in any way, unless you're some kind of clown act with wretched excess in everything [cough! Bootsy! cough!].
If you're a young act, though, uber-nice gear will convince people you are somewhat better than you are. Always has, always will. Deal with it.
You are dealing with bass player trainspotters. A rough estimation is that of 1000 people attending a show, one or two are such things. And one thinks it's bad and the other that it is cool if someone plays a Squier. As for the general audience, they have a hard time even figuring out that a bass has four strings, not six.
And if you are into that kind of nit-picking, avoid the MIM Fenders as trainspotters will also zoom in on those...
