I don't see where I'm fueling any fires at all. "As is" is very common whenever selling something used. You'd be kind of crazy not to include it these days with so many people playing games when they buy things.
I don't know many people who describe in meticulous detail every single tiny thing about something they're selling. Besides, your definition of "like new" or "very good" or "shows signs of normal wear and tear" may be very different than mine. So you post a bunch of pictures, give a description that says enough, calls out any
major issue such as something (i.e. pickup, electrinics, etc.) that isn't functioning, and tack on "as is" to cover any minor things that may or may not bug somebody, and (most)
experienced used buyers are good with that.
To be honest, if you took it to a court or mediator, the most they'd do is have the seller give you $50 or so off IF you could establish the seller was doing something deliberately dishonest. On something as minor as that, they'd most likely tell you to "get real - it's a used bass" and dismiss it out of hand.
And as I said, I'm not passing any judgement here. Everything I ever bought new is close to as mint as it comes no matter how long I've owned it. So I can understand you not being happy since you obviously take as good care of your stuff as I do mine. My point was that "used" is used. And even "like new" isn't the same thing as new.
If that somehow offends you, I guess I'll have to live with that.
