I have never been through anything similar, even tho several people I've jammed with have passed.. I've never had anyone I was in a serious band with pass away, yet, although I know its coming, either for me or for them..
Its gotta be difficult to let things go that have so much personal meaning to you, but are only another piece of equipment to a potential buyer - until they add their memories to that same item.. I kind of hope I never go through that.. I feel sorry for whoever has to go through my stuff..
Friendship is like peeing your pants.. Everybody can see it, but only you can feel the warmth..
