When I heard that Gibson was going to replace their ebony fretboards with richlite, I decided it was time to replace my old wine red Les Paul Deluxe that had been stolen years ago while I still could get an ebony one.
Musician's Friend had two gorgeous and virtually identical tiger-stripped wine red LPs for sale online, but one had a satanic "666" serial number, so I bought the other one. I have the receipt to prove it.
When it finally arrived, in perfect shape, btw, they had sent the one with the satanic serial number. I was not happy.
I have bought a few other guitars and things since then, but not from Musician's Friend. That sale cost them quite a few other sales. Sweetwater, Wildwood and Dave's Guitar got that business instead.
I disagree about electrics being easier to hide mistakes than an acoustic, though. Not if you're playing it clean. Everything gets amplified, mistakes and all. My little Taylor mini is remarkably loud for such a little guitar, but very forgiving with my screw ups. The LP? Not at all.
You probably would have been able to sell that LP at quite a profit to some idiot precisely because of that serial number :-)
