I live in California so all basses in cases - in case the next big one (earthquake) hits. When the 1989 earthquake hit San Francisco I was at work trying to remember what basses I had out, I was under a table, duct work was falling out of the ceiling. My wife and kids were back east visiting family so of course I worried about the basses. On the drive through city streets home the shops storefront glass was bending back and forth this was maybe 20 min. after the quake. Came home and everything that was in a cabinet was on the floor. Went to the music room and everything was in a case but my stacked Gallien Krueger amp. and cabinets fell down like they were thrown. On the GK 400B the steel panel at the back of head was dented in about a 1 inch from the impact. Later I opened it up found a few loose items & plugged them back in, it worked then and still is a distant back up head today. After this long story the message is: if in earthquake country, keep them in cases. I have a Squire Jazz bass on a stand in the bed room, this bass get all the play time. I know it's kind of dumb.
