I was perusing my local Home Depot and came across this tool backpack. Husky 18 in. Rubber Bottom Tool Backpack in Red-68000H-18 - The Home Depot I have used this backpack and it works great for carrying accessories (cords, pedals, books, strings, straps, clothes, tools, etc.) It is very rugged and has lots of pockets. I really like that fact that it stands up and does not flop over. The downside is the weight. It is a bit heavy even when empty.
