My new house was built in 1970's. It's interesting how much smaller closets and stuff were back then. I'm guessing because people didn't own so much stuff. If at all possible, I WILL keep them inside. However, I have them in 2 big plastic totes (the pedals that are not on my boards) and the totes are just sitting in the middle of the floor right now. The room that is going to be my music room is the last room of the house we are setting up. My wife is VERY OCD and so she wants everything in a proper place and out of sight is preferred for her.
We are going to buy a set of shelves that she wants me to put all the CDs on. Right now they are all in little plastic storage containers that hold about 15-20 and they are piled up. That will take up most of one wall; The amps and stuff take up a wall, one wall has a small closet in the middle of it and the last wall is where she wants to hang the guitars. So, doesnt leave me much (if any) place to put them.
So, we will see how it works out, but she isnt going to want those plastic totes sitting out in the room .
