When you’re not here who will inherit your system?

I have been planning to give my system to my son-in-law who is a commercial electrician and plays bass in a heavy metal band. I hope there’s a chance that he will understand how my system works and will appreciate the gear selections I made. A faint hope. But he’s 3000 miles away, their place would not accommodate all this stuff, and he’s probably going to have job/band hearing loss. I need a plan B.

How about the rest of you: any plans?
