with the buying/selling power that GC has it seems to me that they could make a deal with a sting company that would allow them to restring, when needed, all in-house guitars and basses with that brand. that would help with maintenance costs. plus the labor costs could/should be covered under warranty considering the guitars are new-unsold units.
i came from the auto industry and if we had a new car on the lot with a flat tire we didn't wait until someone wanted to test drive it before we fixed the tire. we would pull that car off the lot so no customer could see it and made sure it was right before we put it back on the lot. why should we expect any less when we are looking at instruments?
to me it doesn't matter if it's a $200 bass guitar or a $40,000 car i expect them to be right. if a certain bass is junk knocking $50 off of the price doesn't fix it, that just makes it cheaper junk. we shouldn't expect a $200 bass to play like a $10,000 hand built bass either but warped necks, dead electronics, dead strings and terrible set-ups should not be tolerated on either one.
we as consumers are the only ones who can fix this situation. anything that sounds like " good enough" should never be used when any purchases are being made. if GC, or other sellers, saw their bass sales drop by a large % changes would be made. it's up to us to start the changes
