At least they're electrics.
When I see acoustic musical instruments locked away in vaults or behind glass I shudder. If you leave them unplayed in a quiet environment for a long time they lose their sound as the varnish re-settles. A guitar stored for years will sound dead until it's played for about a week. The only way around this is to store them near stereo speakers so the vibrations keep them alive.

I saw Libby Cotton's Martin guitar at the Smithsonian, locked behind glass, and almost wept.
