The gear matters far less to the audience than you think it does.
We can't tell how they sound from the photos. I'd take a great sounding band wearing street clothes over a spiffy-looking mediocre-sounding group.
I know/have seen a hell of a lot of cover bands who cant play in the same key together get great reactions from people who aren't musicians because they play 1) heavier than the original, 2) slightly faster than the original and 3) have a singer who thinks he is the next Axl/Lee Roth/Bono.
I've also seen some of the finest bands/groups you are likely to hear be slated by other musicians. Ignorance,it seems, is bliss!
Oh yea, I'd have no problem using a squire. I played a Hohner LX90B live for years.
