Someday I'll clear out the garage and have the space for one of these for my cases. I'll have to adapt it slightly for guitar and bass simultaneously. Right now the wife likes the way everything looks hanging on the entry wall so the cases don't get much use. I grab either my mono bag or my inCase bag and take a bass (except for ol big blue, still need a bag for that one).Thanks. Feel free to build one yourself. Here is a quick description of what to do. I used Baltic Birch, but it can be built with lower grade plywood or MDF for a lot less money.
