Collecting guitars has a demographic concern. As boomers age out, the market may sag. Also, collecting them requires expertise, which means one will be in tough competition with savy collectors and unscrupulous forgers.
I have a number of guitars (doesn’t every player?) but only one collectable. It makes me nervous owning it, wondering about value, theft, insurance…
But I get the greatest value from doing what I was told when it was given to me, “Just play it.”
