I just hand my guits over to ChanMin for cleaning. haha.
ok, seriously, I only have 2 guits, but I keep them in a gig bag and hardcase respectively. I typically don't like leaving the guits in the open, cos the strings'll just blacken sooner than I'd expect.
Eventually I'd like to have a mini guitar chamber, but that's when I have enough dough to own enough guitars.
To make the construction of the chamber affordable, I'll just ask ChanMin to help me build it, can hor?
If you're more particular abt humidity, get a dehumidifier for your room in which you leave your guits.
