The wood in most of our basses was once alive, somewhat like the aforementioned bone. The plastic, by a slight stretch, was once dinosaurs. BFD.
And I would not suggest offing a whale for a bass, but if I came across a beached whale bone large enough to harvest as a neck or w/e, I'd bring it home & PM the OP. EIEIO
"I was alive in the forest
I was cut by the cruel axe
In life I was silent
I death I sweetly sing"
Inscription on the face frets of an Elizabethan lute (original in Latin).
Seems recycling "dead" objects in a way honors what was once living as well as enhances those who are alive and able to use it. Like organ/tissue donation, really. Or food....
