I don't know who is worse; people like the seller, or any potential buyers...
I'm all for being conscientious about tone. But I'd like to think there's a limit somewhere, a line, if you will, and on the other side of it, well, you're insane.
I've heard hilarious yet terrifying stories about Eric Johnson's OCD making for six hour soundchecks. We're talking speaker cabinet backplate screws getting 1/4 turns or swapping out 1 brass screw for nickel, etc. And for what?
I play my Warmoths through Line 6 Gearbox and my computer at home. On the rare occasions I gig, the backline is provided by the club. There's no sense getting anal (I said it) about my tone. If it's audible and in tune, I've got 90% of taken care of. The people out front may or may not like the band or the music.
But no one has ever come up to me after a gig admonishing me about my poor awareness of picofarads, choice of wire covering, or the absolute necessity of nitro finishes.
It's usually more along the lines of "You rock!" or "You suck!", and more than occasionally both coming from the same (drunk) person.
If a seller can get a buyer to fork over money for this kind of idiocy, then God bless them. I'm just not going to be one of the people holding the flatware.
I'm also not going to be holding back my opinion on what a bunch of self-important, idiotic horsesh*t is getting shoveled by the sellers.
These people deserve each other.
