NKU-
Please reconsider.
You auditioned and passed. Are they a working band = gigs & money? If so, you might want to be available to work for them. If you want to be out playing, you have to say Yes (even if it's with a bunch of old farts who are my age). You might not want to hang with them, but you could be working.

If they were indeed a working band and would provide a consistent revenue stream, who gives a rat's behind that they didn't recognize your gear?
I suppose its human nature to be defensive of the gear that
you were sold on enough to sink a big chunk of money into, but come on people,
why on earth would anyone get their panties in a wad because someone questioned their gear quality?
Life is too short!
Reading these posts, it seems that a lot of the
posters are a lot more hung up on gear labels than the modern gear ignorant dinosaurs that NKU auditioned for. Its pretty easy to tell the working players from the hobbyists.
Truthfully this bias goes a lot deeper than a bunch of geezers jamming in Cincinnati; there are plenty of top notch, 1st line professional studios doing work for major labels that will send you home if you show up for a session without a Fender.
Search this forum and see what working players have already posted about this, Im not making it up.

Is it "right"? Not by a long shot IMO, I've got some boutique gear, some fairly obscure. I like it, play it when I can, and as far as I can tell it sounds tremendous.
But... it is what it is. Whether or not it's morally or ethically right or wrong, in the play for pay world if you want the money, you pretty much have to have the right tool for the job and in a whole bunch of peoples (ignorant as well as cutting edge knowledgeable) minds for a bass player the
"right" tool are the tried and true big brands.
All of the righteous indignation in the world probably wont change it either.
Getting upset with the geezers is just being petty in my book. If nothing else, hopefully NKU opened their eyes to bass rigs other than Ampeg, and the next time they see an Aggie or other non mainstream brand they wont be so quick to judge!
