Interesting thread... I personally have always been amazed (I'm 69) how many times a new acquisition would be "the one" - - so perfect in tone and playability, so cool, that there's no way it would ever get sold. Bonded for life. But then at some point I'm tired of it, the neck's not so ideal, the tone's not killing me anymore, you all know the drill. And it's gone. Some I deeply regret and wish I had back, but I got tired of them once... I've owned about 300 guitars (most for flipping), many acquired sight unseen, and only 15-20 were special like this. Maybe humans are just inconstant by nature. Maybe the old blues guys were right, have one guitar and get dangerous with it.
