They want you to show up with pro gear because it's a filter that will weed out a lot of scrubs that can't play well. If you're taking the low end seriously, you'll have pro gear. They say "Fender" because it cuts out the guys with 7 string coffee table basses that just want to solo over everything. Everyone wants justification that their Squier is just as good as a Fodera, but it's not. And everyone with a Fodera isn't a lawyer that only plays in his music room. Maybe it's the hipster retro revival thing, but cheap basses are usually not as good as more expensive basses. Period. Squiers are nice instruments and you get a lot of bang for your buck. Be happy. Enjoy it. But I really don't get this need for everyone to think that Squiers are just as good as American Fenders. My Scion tC isn't as good as a Ferrari. I understand that and accept it.
I think it goes both ways there, You don't think some people play Foderas and Sadowskys cause of the name is less well known to a casual person (IE someone who isn't super into bass)
