I've tended to be the guy in our band (and past bands as well) that carries most of the essentials and spares for the band. Lots of mic cables, speaker cables, power strips, extension cords, mics, spare instrument cables, DIs, etc. I find nothing worse than showing up to a gig and not having what we need (long enough extension cords to reach the stage area!). My most recent bag is this one. Cablephyle-CFB-02 Cable and Accessory Organizer Bag The problem I have with it is the construction is sub par (granted it's fairly inexpensive, but it does organize well) and, given the weight it will contain, is soft bottomed and wheelless. In the past I've used multiple milk crates, which tend to loose small stuff and ruin cable ends that end up poking through. Big open boxes/bags tend to be a pain since you have to remove everything to get to that one thing you need at the bottom. Any great recommendations for cable/gear organizing bags?
