My wife is a nurse, not a musician. She can't understand my fascination with (and tendency to accumulate) musical toys. She once said that, should I predecease, all that junk would be on the curb the following Thursday for the trash man.
So, last time we updated our wills, we added a special paragraph saying that, when I die, all my musical gear goes to our number-three son, the starving musician of the family. The rationale is that he'll know best what to do with it all.
